Programming grades

[sean903]

hey guys, I'm making this program which requires the user to enter each grade for each assignment listed so far. What I want to do is, for example..add all the homeworks together and give it a new name, which is going to be "total hw". and so on for the rest(quizes, tests, and extra credit). here's my program. let me know if you understand my question.

#include <iostream>
namespace std;
int main ()
{
int totalhw = 0, int totalquiz = 0, int totaltest = 0, int totalec = 0, int grade = 0;

cout << ("Enter your grade for homework 1: ");
cin >> hw1;
cout << ("Enter your grade for homework 2: ");
cin >> hw2;
cout << ("Enter your grade for homework 3: ");
cin >> hw3;
cout << ("Enter your grade for homework 4: ");
cin >> hw4;
cout << ("Enter your grade for homework 5 ");
cin >> hw 5;
cout << ("Enter your grade for homework 6: ");
cin >> hw 6;

cout << ("Enter your grade for quiz 1: ");
cin >> quiz1
cout << ("Enter your grade for quiz 2: ");
cin >> quiz2;
cout << ("Enter your grade for quiz 3: ");
cin >> quiz3;

cout << ("Enter your grade for test 1: ");
cin >> test1;
cout << ("Enter your grade for test 2: ");
cin >> test 2;

cout << ("Enter your grade for extra credit 1: ");
cin >> ec1;
cout << ("Enter your grade for extra credit 2: ");
cin >> ec2;
cout << ("Enter your grade for extra credit 3: ");
cin >> ec3;
cout << ("Enter your grade for extra credit 4: ");
cin >> ec4;
cout << ("Enter your grade for extra credit 1: ");
cin >> ec5;

I don't really get what you're asking but I have to say that your code is seriously long-winded. Have you read about arrays or loops yet?

I would take the time to study them because if you understand them you can turn all that redundant code into something like this:

int homework[6];  // array 

	for (int i = 0; i < 6; i++) {   // count controlled loop
		cout << "Enter your grade for homework " << i+1 << ": ";
		cin >> homework[i];  // note: arrays start at 0, not 1  
	}

If you merely want to add the homework scores just declare the array int hw[6];

Then fill it up: (arrays start at zero by default)

cout << ("Enter your grade for homework 1: ");
cin >> hw[0];
cout << ("Enter your grade for homework 2: ");
cin >> hw[1];
cout << ("Enter your grade for homework 3: ");
cin >> hw[2];
cout << ("Enter your grade for homework 4: ");
cin >> hw[3];
cout << ("Enter your grade for homework 5 ");
cin >> hw[4];
cout << ("Enter your grade for homework 6: ");
cin >> hw[5];


for (int i = 0; i < 6; i++)
      totalhw += hw[i];    //adds them all up (totalhw += is the same as totalhw = totalhw + ) 

P.S.- you have a typo on the second to last line and it doesn't look like you declared any of the variables you are using to store the grades.
