Can't stop endless loop...

Hello, I have this problem and I can't stop it looping only 'A'...it won't print 'A' through 'Z'?...

Code:

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



int main()
{
    cout << "here is a list" << endl;
    char letter = 'A';

    while (letter <= 'Z')
    {
        cout << letter << '\t' << static_cast<int>(letter) << endl;
    }

    return 0;

}

 

letter is always equal to 'A' that's why it never stops.
you must increase its value by one inside the while.

change this

Code:

        cout << letter << '\t' << static_cast<int>(letter[COLOR=Red]++[/COLOR]) << endl;
