C++ :: Declaring A Display Function Prototype Only That Displays A Student Test Scores In The Format
Oct 28, 2013
so in declaring a display function prototype only that displays a student test scores in the format (student name tab number of scores tab test scores )
is this right?
#ifndef STUDENTTESTSCORES_H
#define STUDENTTESTSCORES_H
#include <string>
using namespace std;
class StudentTestScores{
private:
[Code]...
and also how do we call the display function if it is in a class from the header file onto the main cpp file.
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.
I'm trying to basically have a user input the amount of test they want averaged, then have the user input the test scores. Send the test scores to a function and have them ordered in ascending then send it to another function that averages it. When I wrote the function I keep getting the address back instead of the actual values.
i have so far, and im having trouble finding a way to store 5 test scores for each student that has been entered. for example: enter name: chaotic enter id number: 12312312
Enter test score 1: Enter test score 2: Enter test score 3 etc.......
I was doing a side programming challenge in my workbook that asked me to dynamically allocate and array for test scores. So far I have an array that will accept an integer to allocate the amount of test scores and then will accept integers to populate the array, however when I try to cout the contents of the array the numbers are absurdly different than what was put in. Here's my code:
#include "stdafx.h" #include <iostream> using namespace std; void main() { cout << "How many test scores?" << endl; int scores(0);
[Code] ....
And this is the output screen: How many test scores? 4 Enter test score 1: 22 Enter test score 2: 33 Enter test score 3: 44 Enter test score 4: 55 -33686019 18472 55656634 201345063 Press any key to continue . . .
Why am I getting these crazy numbers? I've looked back and forth from examples in my book and it doesn't look like I'm doing anything wrong.
I was asked to create a C++ program that allows a user to take a test with series of different questions, and also retake the test if they choose to. I have been able to do that. But the other condition is to display the highest and lowest scores (highest and lowest correct answers) the user got, and in which test they got that score. For example, if the user takes the test 3 times, in which test did they get the highest score, and in which did they get the lowest score.
This is how far I went with the program. The code below only let the user take the test as much as they want, and tell them how many times they took it, and the last score they had. My idea is this, if I can make a variable store each test score, then I can compare them. But since there is no definite number of tests to be taken.
#include <iostream> #include <string> using namespace std; void main() { int correct = 0; int wrong = 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 need to sort these students based on their test scores.
My biggest problem is with my sort function. I am not sure of the syntax to call the items the proper way. I also don't know how to call the function properly as I know that i can't pass a int to a struct. Also not sure about the z malloc. Just threw that one in there.
Code: struct student{ int id; int score; }; void sort(struct student* students, int n){ /*Sort the n students based on their score*/
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'm trying to create a two dimensional array that displays zeroes in a 10 by 10 format. But I don't really know how.I've been playing around and this is what I have so far:
Code:
#include<stdio.h> int main(void) { int my_array[10][10]={0}; int i,j;
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;
I am building a linked list and i need to display function i have. The display function displays all the letters of the word entered instead of the word itself. below is my struct, one of my functions and the display function.
Write a program that a prof can use to enter the test marks of several students and which calculates the average mark of each student. Ask the user how many students he has, then ask him to enter each student's marks. When 999 is entered, calculate the average mark for that student (not counting the 999) and print the average. Then go on to the next students until the marks for all students have been entered, calculated and the average printed.
Code: #include<stdio.h> main() { float student,mark,total=0; float a,b,c; int num = 999; printf("
I have a problem on my program. I want to display the scores on notepad. I can display it but the problem is every time I play the game the previous score got erased and replaced by the new one.Here's my code.
cout<<" Enter your name: "; cin>>a; cout<<endl<<endl; cout<<" Your name is "<<a<<" and your score is "<<right<<endl<<endl; ofstream MyFile ("score.txt"); MyFile << a <<" "<<right; MyFile.close ();
I'm new to C programming and in my first computer science class. Our assignment was to write a program that displays each digit of an integer in English. I wrote the following but cannot figure out why it won't display zeros. When I execute and type in the number 1,000, I get "zero."
Code: #include <stdio.h> int main (void) { int x, y = 0; printf ("This program displays each digit of an integer in English.
i wnt to display student who get highest marks among them...i have code for finding maximum marks from them but don't kne how to print only top 5 student...
Code:
static void Main(string[] args) { Console.WriteLine("Please Enter Number of Students :"); int n = Convert.ToInt32(Console.ReadLine()); StudentDetails[] student = new StudentDetails[n]; for (int row = 0; row < n; row++) { Console.WriteLine("Please Enter Student name :");
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.
I have a project that I am working on and I have gotten stuck. I am getting a couple errors and would like to see how I can complete the program. Not very long of a program at that. My instructions are:
Write a program to calculate averages. Create a method named ReadData that will load a two dimensional array, named scoresArray, with the following data from a file:
Create a method named DisplayAverages that will display the emplyee number (number starting 1324, 4356 etc) and the average of the three test grades. DisplayAverages will have one argument, the scoresArray. Your output should closely resemble the following.
Round averages to one decimal place. Passing arguments is important for this program. No global variables are allowed, except for the streamReader and the streamWriter. The scoresArray must be declared in Main and passed as an argument to the methods ReadData and DisplayAverages.
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using LibUtil; using System.IO; using System.Text.RegularExpressions;
[Code] ....
When I run the following just to see where I am getting I get the following error:
UsersJoeDocumentsVisual Studio 2013ProjectsCIS110Program12Program12Prog ram12Dat.txt was opened Unhandled Exception: System.IndexOutOfRangeException: Index was outside the boun ds of the array. at Program12.Program.ReadData(Double[,] scoresArray) in c:UsersJoeDocument sVisual Studio 2013ProjectsCIS110Program12Program12Program.cs:line 66 at Program12.Program.Main() in c:UsersJoeDocumentsVisual Studio 2013Proj ectsCIS110Program12Program12Program.cs:line 24 Press any key to continue . . .
What am I missing here? I believe I have passed the arguments properly, but I am unable to declair the array within the bounds of the array?
The data source of my grid is a list. Lets call the list list<objectX> listC where objectX is the type. objectX looks like this (this file cannot be edited):
public string otherProp1 { get; set; } public double otherProp2 { get; set; } public TimeFrameV endTimeframe { get; set; } public double otherProp3 { get; set; }
[Code]....
I have 4 columns bound to fields in objectX. Two of which is bound to TimeFrameV objects. Initially endTimeframe and startTimeframe were strings, but not anymore. I have been using "FieldName" property to bind the fields.
I want to access all three fields in TimeFrameV. I have a method FormatTimeFrame(TimeFrameV timeFrame) that takes TimeFrameV object as a parameter and returns the desired string result depending on the variable values in the object. Here is what I want, i want/need to somehow pass Fieldname property value. But it's a string and I am not sure if I can parse into int TimeFrameV object.
I want to display my data in rich-text box in the tree like structure,i fetch the data from the data base MSACCESS & i want to print it on my rich-textbox, what can i do ?
But the output rows are not aligned as shown in the attached picture. There a two problems.
1. Data rows don't align with the header row. 2. When the first element of a row changes to two digits, the other elements are shifted.
According to MSDN [URL] ...., CString::Format() works the same way as printf(). I wrote a small program using printf() to do the same thing, and the output in the console are perfectly aligned.
I am coding in C++ an implementation of BTree Insertion. I want to display the contents of the Tree in a per-level format. After writing functions and trying to run. I get the error Undefined reference.
