Visual C++ :: Get Program To Read From File Of 15 Scores?
Dec 10, 2014
I'm trying to get the program to read from a file of 15 scores. 10 are quizzes 5 are exams. I want my program to read from the input file the first name "or" last name and if the user puts a different name, the program Gives off an error screen message
Code:
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
using namespace std;
const int NUM_STUDENTS = 20;
const int NUM_QUIZZES = 10;
const int NUM_EXAMS = 5;
Okay so suppose that a text file grade.txt contains an unspecified number of scores. How would I program that reads the scores from the file and displays all the scores, their total and average? Scores are stored in the format of one score per line. Im having trouble with the whole #include <fstream> file and how to lay it all out in visual studio.
My program reads data from a txt file and it displays the test scores and the sum of the scores, and it also shows the max and min from the scores , so far only one number shows up from the scores instead 10 and i think my sum is wrong too, but i cant get the max and min to work ...
I am currently in a beginner C programming class. I have written most of my code and the problem that I am running into when i compile and run the code. I am able to input more than required scores for input. I think my code is wrong from line 126-136. The program runs fine with no errors. I'm just unable to input the required number of scores allowed.
/************************************************************************* * A program to calculate grade. *************************************************************************/ #include <stdio.h> #include <ctype.h> #include <stdlib.h>
Write a program that scores a blackjack hand. In blackjack, a player receives from two to five cards. The cards 2 through 10 are scored as 2 through 10 points each. The face cards - jack, queen, and king are scored as 10 points. The goal is to come as close to a score of 21 as possible without going over 21. Hence, any score over 21 is called "busted". The ace can count as either 1 or 11, whichever is better for the user. For example, and ace and a 10 can be scored as either 11 or 21. Since 21 is a better score, this hand is scored as 21. An ace and two 8s can be scored as either 17 or 27. Since 27 is a "busted" score, this hand is scored as 17.
The user is asked how many cards she or he has, and the user responds with one of the integers 2,3,4, or 5. The user is then asked for the card values. Card values are 2 through 10, jack, queen, king, and ace. A good way to hande input is to use the type char so that the card input 2, for example, is read as the character '2', rather than as the number 2. Input the values 2 through 9 as the characters '2' through '9'. Input the values 10, jack, queen, king, and ace as the characters 't', 'j', 'q', 'k', and 'a'. (Of course, the user does not type in the single quotes.) Be sure to allow upper - as well as lowercase letters as input.
After reading in the values, the program should convert them from character values to numeric card scores, taking special care for aces. The output is either a number between 2 and 21 (inclusive) or the word Busted. Use fucntions, multiway branches, switch statements or nested if-else statements. Your program should include a loop that lets the user repeat the calculation until they are done doing so.
The code runs properly for the first card but then it asks if the user wishes to repest the program. I need to claculate the value of all cards before it asks for that. Here is my code:
#include <iostream> using namespace std; int main() {
This program is incomplete as I am having difficulty creating the function that needs to find the number of perfect scores entered by the user. I have everything but the function complete ,here is my code:
Code: // Write a modular program that accepts at least 10 integer test scores from the user and stores them in an array. // The main should display how many perfect scores were entered (i.e., scores of 100), using a value-returning countPerfect function. // Input validation: Do not accept scores less than 0 or greater than 100.
#include <iostream> using namespace std; int countPerfect(int intArray[], int); // Function prototype
Below is the program I have written yet I can't seem to get it to work right.
// Purpose: generate a class average for entered test scores // Input: # of tests, test scores // Output: total number of tests, average score of tests
#include <iostream> #include <iomanip> using namespace std; int main() { //declare variables short numberOfTests = 0;
Write a program that prompts for and reads in test scores. You may assume that valid test scores will be integer values between 0 and 100. You may also assume that the user will not enter more than 35 test scores. Use a preprocessor directive to define this value. User input will be complete when the user enters a -1 for the test score. When all of the test scores have been entered, the program will print out the scores. Use a while or do-while loop to read in the values. Use a for loop to print out the values.
Sample output: Enter test score 1: 88 Enter test score 2: 67 Enter test score 3: 74 Enter test score 4: 94 Enter test score 5: 79 Enter test score 6: 56 Enter test score 7: -1 Number of scores entered: 6 Test scores entered : 88 67 74 94 79 56
I have created a program that allows for a user-defined number of test scores as input. After the user enters these scores, the program calculates the average test score. Here is my code:
#include <iostream> #include <iomanip> using namespace std; // Function prototypes double getAverage(double*, int);
[Code] .....
I am having trouble with the final part of my program. How do I pass the array of test scores to a function that calculates how many people got an A (90+) on the test? The final output should look like this:
The average of those scores is: The number of A grades is:
I am writing a class that dynamically allocates an array that holds a user-defined number of test scores (test scores go from 0 to 10 both included). Once all the test scores are entered and validated (values only between 0 and 10, both included), the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates theaverage of all the scores.The main program should display the sorted list of scores and the average of the scores with appropriate headings.
Find the attachment. change the file extension *.lct instead of *.txt. I like to read ASCII Data into Hex, Example : Data "A" as "41" (Refer the jpeg image). How is possible?
I am working to make a translating software from an Urdu sentence into Hindi and vice versa, i am using visual c++ 2010 software with c++ language. i have written an Urdu sentence in a text file. now i want to get a single character one by one from that file so that i can work on it to convert it into its equivalent Hindi character. when i use get() function to get a single character from input file and write this single character on output file, i get some unknown ugly looking character placed in output file. My code is as follows
I have been working on a program to scanfile and whenever it encounters what the user wanted it prints it, and it is all right less the first line of the file that the program jumps,
Write a program that reads several strings from a file. Display the number of words then display each word as shown in the sample below. Assume that the maximum number of string in the file is 100.
Sample Input (.in): Smitty Werbenjagermanjensen. He was number 1!
Sample Output:
Total Number of Words: 6
Word[0] = Smitty Word[1] = Werbenjagermanjensen. Word[2] = He Word[3] = was Word[4] = number Word[5] = 1!
I am trying to get my program to calculate what point goes in what quadrant using a file. But msy program is not reading the values from the file and also it is not running so im not sure what's wrong with it.
//This program uses a fstream object to write data that will read the values of a (x,y) point from a file. //add the appropriate preprocessor #include <fstream> #include <iostream>
I am doing an exercise that reads in a text file and loads the data into a struct. My problem is it doesn't read anything from the text file. I think it's the way I'm loading the data. Oh, it does read in the first record that tells the program how many contributor records to create, but nothing after that. Here it is:
Code: // #include <iostream> #include <fstream> #include <cstdlib> const int strsize = 30; const int SIZE = 60;
I only get like 500 chars, so I tryed a lot of different funcs until I finally realized that they reached the end of file "early" well it thinks that one of the chars in it is an end of file and it's located at the start. So I really don't know what to do with it because every func doesn't see the rest of the file at all.
I am currently writing a password generator in Microsoft Visual Studios 2010 Professional. The section I am having a problem with is the practical password. It is suppose to randomly read 3 words from a text file and then display it in the text box. The program will compile and run but when I hit generate I get "True True True" and not three random words. Then this warning shows up:
Warning C4800: 'char *' : forcing value to bool 'true' or 'false' (performance warning)
//Code is from the form1.h file. I can post the rest of the code if need be but I just included my includes and the problematic section
I am writing a program in which the computer will read a txt file and encypt it. The encryption works fine, but the computer cannot read the file perfectly. If there's a newline, the scanning process stops. For example I have the following text in the txt file.
One two three four five (newline) Six seven eight
The computer will stop reading after 'five'. I assume that is because I use fgets.
So I'm trying to create a program that allows one to read/write on to output.txt. I though I had everything set up right, but its only writing one word to the text file. Heres the code.
#include "stdafx.h" #include <iostream> //Needed for User Input #include <fstream> //needed for ofstream #include <string> // needed for strings #include <windows.h> //needed for Sleep #include <cstdlib> //Needed for return EXIT_SUCCESS;
using namespace std; int main() { ofstream outputfile; //allows to read and write to files

If I type Puppies Are Cute and go to output.txt, the only thing written in the text file is Puppies.
I'm new to programming and i'm trying to do a certain task. I want to use a for loop to read certain data from a txt file and print them to a console. I'm trying to read student names and their grades.
