Alternate Solution 2

[remember to indent and comment appropriately]

//credits.cpp

// Programming Assignment #2

// Where Credit is Due

// using string library

#include <iostream>

#include <string>

using namespace std;

int main(){

char endchar;

int n=0, credits;

float sum=0, mean;

string StudentID;

cout << "To stop this program, enter a '000' for Student ID.";

cout << "\n\nEnter Student ID: ";

cin >> StudentID;

while (StudentID != "000") {

cout << "Enter number of credits: ";

cin >> credits;

cout << "\nStudent " << StudentID << " is taking " << credits << " credits.\n";

sum += credits;

n++;

cout << "\n\nEnter Student ID: ";

cin >> StudentID;

}

mean = sum / n;

cout << endl << "=============================================" << endl << endl;

cout << "The average number of credits carried by students in this \n";

cout << "class this semester is " << mean << endl;

cout << "\n\nType any character and press Enter to close this window. ";

cin >> endchar;

return 0;
