System("pause"); not working corectly
Well i'm having a very hard time with just one simple little issue and i haven't been able to get around this problem at all..
I wrote a program where the user inputs info and then the computer prints results back to the command prompt window.. Well here is the code i hope that someone can figure this out for me.. or help me figure it out...
Two files for reference::
//file1.cpp
//List the include files
#include<stdio.h>
#include<iostream.h>
#include<stdlib.h>
//the struct that is being made is being used outside this source.. Look at the linked file strudent_record.h
#include"student_record.h"
//Define an array of student records using the Student_Record struct
struct Student_Record students[3];
//How to compute the grade and a way to find out which student you are on
void compute_grade(int j) //index was int to keep track of which student was being tested
{
float average = (students[j].labAverage + students[j].testAverage) / 2;
// give test results on what grade the student should recieve
if (average >= 89.5)
students[j].grade='A';
else if (average >= 79.5)
students[j].grade='B';
else if (average >= 69.5)
students[j].grade='C';
else if (average >= 59.5)
students[j].grade='D';
else
students[j].grade='F';
j++;
}
//Define a function to input a student record, which consists of all the elements of the Student_Record struct
//This function should take the subscript of the student array as input.
void input_record(int i)
{
cout << "\t\t\t\t--------------\n\t\t\t\t| |\n\t\t\t\t| Input Info |\n\t\t\t\t| |\n\t\t\t\t--------------\n\n\n";
cout << "\t\t\t\t Student " << i + 1 << "\n\n";
cout << "Please Enter Student's " << i + 1 << " Last Name:\n";
cin >> students[i].lastName;
cout << "\nPlease Enter Student's " << i + 1<< " First Name:\n";
cin >> students[i].firstName;
cout << "\nPlease Enter Student's " << i + 1<< " Id#:\n";
cin >> students[i].studentId;
cout << "\nPlease Enter Student's " << i + 1<< " Lab Average\n";
cin >> students[i].labAverage;
cout << "\nPlease Enter Studen's " << i + 1<< " Test Average\n";
cin >> students[i].testAverage;
system("cls");
}
void output_record(int i)
{
system("cls");
cout << "\t\t\t\t---------------\n\t\t\t\t| |\n\t\t\t\t| Report Card |\n\t\t\t\t| |\n\t\t\t\t---------------\n\n\n";
cout << "\t\t\t\t Student " << i << "\n\n";
cout << "\nLast Name: \t" << students[i].lastName;
cout << "\nFirst Name: \t" << students[i].firstName;
cout << "\nStudent ID#: \t" << students[i].studentId;
cout << "\nLab Average: \t" << students[i].labAverage;
cout << "\nTest Average: \t" << students[i].testAverage;
cout << "\nStudents Grade: \t" << students[i].grade;
system("pause") // here is where i have my problem it will pause but only after you hit it twice and it doesn't do it when it should..
//These are a few things i have tried to do to go around this problem. inputting what i just call a stepper by using an int of x and then placing in a cin > x; so that you type a key and press enter to move on.. that hasn't worked.. i have also tried to force a print before the pause.. that hadn't worked.. there has been many more things but i just can't think of what else to do to fix my problem..
}
void main(void)
{
int i;
for (i=0; i < 3; i++)
{
input_record(i);
compute_grade(i);
}
for (i=0; i < 3; i++)
