C++ :: Multiple Quiz Program - Adding High Score For Each User Stored In Binary File
Jul 11, 2014
I am making a multiple quiz program. So everything is working fine, except for the part where i'm trying to add a highscore for each user which is being stored in a binary file. I have added a sample of the program containing the error. This isn't the actual program, which is very long.
class user { //The collection of all info pertaining to the users
char user_id[50];
public:
int hscore1;
user() {
strcpy(user_id,"NULL");
hscore=0;

I've made a game and a dialogbox to show up asking to enter a nickname.
The problem is After entering the nickname, it won't show on the highscore list below (textbox)
Where can the problem be? Below is my code:
private void btnPlay_Click(object sender, EventArgs e) {
if (txtName.Text != "") {
Settings.Name = txtName.Text.ToString();

I need to create a program which could create text files of the bits stored in avi file/binary file. My first requirement is to show 0s and 1s in the text representation . My second requirement is to create an avi file from this text file. I have tried few codings but either they give me error or they not playing the reconverted binary files.

You are to write a C program that grades a true-false quiz. The quiz data will be available in a text file; here is an example:
Quiz #8 (09/22/14) (corrected version)
TTFTTFTFTF
0080 TTFTTFTFTF
0340 TTFTFFTFTF
The first line in the data file is a comment that you may assume can be up to 80 charac- ters long; it cannot be blank. The second line contains the answer key for the 10-question true-false quiz. The following lines in the data file contain a student's id number in column 1 followed by their answers for the quiz in column 2. A 0 (zero) on a line by itself indicates that there are no more students to process.
Write a program that first reads in (from standard input; more on this in a moment) the comment line and answer key as strings followed by each student's data. Store the student's id numbers in an array. You are to "grade" each student's quiz using the key provided fol- lowed by recording their scores (in a second array) in order to be able to print them out later. You do not need to use an array of strings or characters in your program. Write your program allowing for up to 100 students, and you may assume that at least 1 student will have taken the quiz.
You should create test data text files and provide the data to your program using redirection from the command line (see the sample run below). Your program should output the number of students who took the quiz, the average score, the best score, and a table showing each student's id, score, and grade. The formatting, spacing, and labels in your output should 1 match the sample run below exactly.
Your program should determine each student's grade as follows: if the score is equal to the best score b or b−1, give an A. If it is b−2, award a B. Give C's for any score that is equal to b−3 or b−4, a D for b−5 and an F for all others.
Alright So I'm just stuck at comparing the key answer with student answer here is my code comparing one student's answer with the answer key . is that right ?? One more thing for some reason when i try to print answer[0] the result is nothing why is that
Code:
#include<stdio.h>
int main(void) {
char comment[80];
char answer [10];
char studentans [10];
int n=0,i=0,x=0;
int ID[10];

Currently in development of a cookie clicker clone (for fun)
I am stuck at the idea of the "Cookies Per Second" thing.
Is there a way to implement a per second adder thing that doesnt actually effect the game play (eg even though the player may not be pressing C every second a cookie (or more) will be added, or if they can press C more than once a second, every second a cookie will be added... If you get what I mean).
Code is below if you would like to look />
MAIN.cpp
#include <iostream>
#include <conio.h>
#include <Windows.h>
#include "Shop.h"
#include "Varis mate.h"

Following is the program I wrote it basically takes 9 inputs and then save them into binary file. then print out the data stored in binary data and find inverse of it then print the inverse out. but its stuck in a loop somewhere.
Code:
#include <stdio.h>
int main() {
int a[3][3],i,j;
float determinant=0;
int x;
FILE *fp = fopen ("file.bin", "wb");

I'm making a quiz game in c++. I've already completed it. But now I've thought of creating a profile and saving the progress for the user so when he enters his name the game continues frm where he had saved it.

I have started using code::blocks for practicing ,(was using bloodshed dev C++ til now). The thing is that m not able to compile multiple programs stored under a single project , as i have created project by the name of a topic and have decided to solve all problems related to that topic under that project.
When there was only one .cpp file in the project it compiled successfully ,but as soon as i created a second file and compiled it it says "main can be declared only once"

When you have to write data on a file in binary mode multiple times (without closing the file), is the put pointer left where you ended writing the last time, or do you have to use tellp() or seekp() again and again to make sure you write at the right place?
I would have the same question about the get pointer, does he stay in place after you're done reading something (without closing the file, of course), or do you have to set it back at the right place with seekg() ??

So, if I'm right, computer store their data as binary values. So if I write int x = 5; , my computer converts the value of x from decimal (5) into binary (101) and stores it in memory as a a binary number. If I print that value on the screen that value is converted(by default) back into a decimal number before being printed on the screen.
Now, my question is if there is any way to print the value of x directly into binary(as it's stored in memory) without it being converted back into a decimal value?

Write a C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.
This is a sample output. Notice how the program prints a counter (1, 2, 3, ) for user keep track of how many numbers were entered so far. Include this feature in your program.
I have tried different ways to get the result from while loops, do while, and if-else statements. We have not done any max/min problem in class and the book was kind of vague. We have not learned arrays yet in class and I can't figure a way to compare the integers the user inputs as it is an infinite(from what I am reading) amount aloud. The problem I am seeing is the loop works and stops with the sentinel value but the INT_MIN is using the sentinel value. I also have not addressed the input of negative numbers yet with the first program I wrote, maybe one of my problems.
Code:
/*File:HW2Q3.c,
A C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.*/
/*header files*/
#include<stdio.h>
#include<limits.h>
/*****start program*****/
int main() {
[Code] ....
I have also tried this way as well, min value still comes back as -1 the sentinel value, and the else statement is being ignored. I am sure it is something silly but I am lost and confused at this point.
Code:
/*File:HW2Q3.c,
A C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.*/
/*header files*/

Making a game of checkers on C++ win32, visual studio
when i want a piece to move, i type:
cout << "What piece do you want to move? (C4)" << endl;
i type in 'cin' after to get the players input, but how do i get it to store the players input in a certain variable? im going to have a list of variables:
string a1
string a2
string a3
etc
so if the user types in a2, it automatically goes to that variable and then asks the user "where do you want the piece to be moved to?".

In class we were asked to create a C++ BTree program that would allow a user to input the following data types and then store said data in a .txt file:
0. ID 8 bytes
1. First name 30 char
2. Last Name 30 char
3. Street Address one 30 char
4. Street Adress two 30 char
5. City 30 char
6. State 20 char
7. Zip 10 char
8. Country 30 char
(I'm not particularly asking for full code, pseudo code would also be great). I had a great deal of my work done, unfortunately, the computer I was working on crashed, corrupting my files.

For my code, I want the user to enter 4 integers, which get stored in an array. Here are the lines I wrote relevant to this part:
Code:
printf("Enter 4 integers:
");
scanf("%d %d %d %d," &a, &b, &c, &d);
z[4] = { a, b, c, d};
Would this be correct?

The program is supposed to have a method called Hitscore that adds a score between 0 and 1000 inputted by the user to the total score and increases level by one and print the score to the screen and which level they last completed after each entry . Have the user continue inputting scores to the program until the gamer has finished all 10 levels. After 10 levels, use a method you create called PassScore to have the program compare the score to avgscore (5000). If the score is less than avgscore, have the code respond "You are not angry at all. " if it is above avgscore, then have it respond "You seem quite angry, calm down. " and if it is exactly 5000, have it respond "Average, just average. "

#ifndef ANGRYBIRD_H
#define ANGRYBIRD_H

So I have an issue with a homework assignment that I am coding. I am attempting to get a function to iterate through an array and search for a number that was stored in an array by the user. So far I can take the number, get the numbers displayed but in my menuChoice2 function, for some reason the program is not confirming whether or not the number is entered, and is only telling me that the number has not been found, instead of confirming that the number is in the array.
Here is my code thusfar:
#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
// Variables that are Globally declared
int menuChoice = 0;
int usernum[1000] = { ' ' };
[Code] .....
To be clear I am not getting any errors but something is telling me that the error is in the formatting of menuChoice2.

i'm trying to write a calculator. the user will enter the terms and they will be stored in arrays. i will be storing those terms in string arrays and then later turn them to double to work with them. but the user should be able to enter terms like sin(252) and the program should be able to recognize it and calculate it.

I've been taking a C++ class, and for a project we need to do, we have to create a simple quiz show game while putting the high scores and names inside a .txt file. We have lessons we can look at to complete it while learning. But at the end there's always a challenge that we should complete to show that we've actually learned the information. For the challenge, we needed to take the information in the .txt file and reset it to its original information. So say there's 5 people preset that have high scores, then a person plays the game and the program asks if they'd like to reset the list. If the user inputted 'y' or any key that needed to be pressed, the program would reset the .txt to its original information.
This is the code that creates the program.
// Include Libraries
#include <iostream>
#include <string>
#include <fstream>
// Include standard namespace
using namespace std;
// Declare Global Variables
int Guess;
int Winnings;
[Code] ....
It works how I need it to and there aren't any problems, necessarily, but I want to know if there's any, more efficient, ways of completing this task. Like if there's any already made function of resetting a file.
This is the code that resets the file. As you can see, it just uses the information earlier in the code inside the if statement. Is there any pre-made function or method of resetting a file?
cout << "Would you like to reset the high scores list? (y or n): ";
cin >> ask;
if (ask == 'y')
{
High_Score[0] = 25000;
High_Score[1] = 12000;
High_Score[2] = 7500;
High_Score[3] = 4000;
High_Score[4] = 2000;

Instead of using:
Code:
x=x+k
y=y+k
z=z+k
Is there a more elegant method of adding the same constant to many variables?
Something like: Code: (x, y, z) = (x, y, z) + k ??

My application requires the user to add sales to images, this is done by displaying the image for the GUI, and then the user would add sales using that images ID which is brought in from the database.
In part this is 2 questions, first question is what is the best way to generate a List for use when adding the sales to the database. The List would need multiple strings for each sale. So for example:
Image 1 (Sale)
- JPG ID
- Product ID
- Product Quantity
So i'm going to assume i'm best creating a new instance of a custom class for each sale, and then add each instance to a List<Sale>?
public class Sale
{
public int SaleID { get; set; }
public int JpgID { get; set; }
public int SaleQty { get; set; }
}
Then I need a decent way to update this List with the GUI controls. So maybe get the JPG ID and set name of the Sale Class Instance to the ID, in this way its unique and I can update that instance when it comes to increasing the sale of a product or decreasing it.
Second part comes to the design of the GUI of adding sales, when I made this using HTML/PHP that was easier. It looked something like this:
If I wrote some code to generate that kind of design again in C# it going to require many Controls, wouldn't that be a bit intensive on the system? I just want something which looks great but also functions good.
At some point I'm going to switch to WPF, but I just need to get a working prototype working now which my client can use, and then update it when I have more time as I have got other Web Related projects that need doing, so at the moment WPF is out of the question.

I have the following code which allows me to add the pdf files if I give the exact name and path of the file. But I have multiple pdf files in a folder which I want to add to each cell in the first column. I am having trouble thinking of the logic to have a for loop for a folder which contains the pdf files.
private void button1_Click(object sender, EventArgs e) {
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
xlApp = new Excel.ApplicationClass();
xlWorkBook = xlApp.Workbooks.Add(true);
[Code] ...
But this is very very rough draft. I have say 20 files in the folder pdf with different names(Title). How can I add all the 20 pdf files in the excel sheet?

I'm writing a program to keep score of a game of bowling. Whenever I run the program, it comes up with the correct starting point, but whenever i type in the first number and click enter, the program stops running and it gives a return value of something similar to 3221225477. Here is my code. I think the problem might be that I'm not using pointers..? but I could be way off..I'm new to programming.
#include <stdio.h>
int main() {
int frame[10][3] = {{0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0,0}};
int frameOutcome[10], frameTotal[10], currentFrame = 0, totalScore = 0;
