odd error?

[thomasstambaugh]

Before you yell at me for bad variable names, this is just one random practice assignment in school >_>

Okay here is the code:


#include "stdafx.h"

#include <iostream>
#include <iomanip>
using namespace std;

void main()
{
int x[100];
int y,z,l;
float sum,avg; // y is for the first loop, z count the amount of numbers, l is the second loop, sum is the sum
char quit; // are you quiting or not

for (y=1;y<=100;y++) {
x[y]=0;
}

z=0;

for (y=1;y<=100;y++) {
z=z+1;
cout << "Enter a number: ";
cin >> x[y];
cout << endl << "Was that the last number? (y for YES): ";
cin >> quit;
if (quit=='y' || quit=='Y')
break;
}


sum = 0;

for (l=1;l<=z;l++) {
sum = sum + x[l];
}

avg = sum / z;

cout << endl;
cout << "You entered " << z << " integers";
cout << endl << sum << " is the sum";
cout << endl << avg << " is the average";

cout << endl;
system ("pause");
}



Now here is my problem. It works, so I'm not super worried, but it keeps saying the stack around variable x is corrupted after the program ran. I don't know why, and the teacher said he's never seen that before. Any ideas? Was I using the variables wrong or something?

Yet again, sorry for the bad variable names

Isn't this a Windows program?

[maheshgupta024]

You have declared variable x of size 100
and using the variable from 1 to 100, plz note index starts from 0 to 99 only
change the index from 1-100 to 0 - 99 it should work

I'm working in windows right now simply because I'm at school.

Would it be different if I was in Ubuntu? I use Ubuntu at home and Java seems to be the same

[maheshgupta024]

In linux it works well when the memory is alloted for you. When you are accessing any location is out of your memory location. It gives you a segmentation fault.
I think in your small program it should not create any problem.
