What’s wrong with the following code?

[minuss273]

I have stumbled upon an exercise on Michael Dawson's book: Beginning C++ Game Programming. It asks to find what is wrong with the following code. I think it is the <= operator, but i have my doubts. Any ideas? Here is the code:

for (int i = 0; i <= phrase.size(); ++i)
   cout << “Character at position “ << i << “ is: “ << phrase[i] << endl;

Yes, the size() function gives the number of elements in that array, since arrays count from 0 and not 1, there will be no n'th element for an array of size n.

Quick test...

code...

#include <iostream>
using namespace std;

int count = 0, input;
int main()
{
    string phrase;
    cout << "Please input a phrase: " << endl;
    cin >> phrase;

      cout << endl << "With phrase.size() " << endl;

    for (int i = 0; i <= phrase.size(); ++i)
        cout << "Character at position" << i << " is: " << phrase[i] << endl;

    cout << endl << "With phrase.size() - 1 " << endl ;


    for (int i = 0; i <= phrase.size() - 1; i++)
        cout << "Character at position" << i << " is: " << phrase[i] << endl;
        return 0;
}

output..

Please input a phrase: 
test

With phrase.size() 
Character at position0 is: t
Character at position1 is: e
Character at position2 is: s
Character at position3 is: t
Character at position4 is: ?

With phrase.size() - 1 
Character at position0 is: t
Character at position1 is: e
Character at position2 is: s
Character at position3 is: t
