I'm studying for an exam and this is on my practice test. The question is "Which type of error does the following code fragment cause?"
I was pretty sure there would be no errors, but I also can't get it to compile in VS13, I get the error:
Run-Time Check Failure #2 - Stack around the variable 'foo' was corrupted.
const int MAX = 500;
int main(void)
{
int foo[MAX];
for (int i = 0; i <= MAX; i++)
{
foo[i] = i * 2;
cout << foo[i] << endl;
}
cout << "Press any key to exit." << endl;
cin.ignore(2);
return 0;
}
Valid indexes for foo are from 0 to MAX-1 inclusive. MAX is past the end of the array.
Your loop runs up to, and including, MAX. This writes beyond the end of the array, corrupting the stack.
Either increase the array size to MAX+1 so that MAX is in range; or change the loop condition to i < MAX to stop before reaching MAX.
