string temp is equal to "ZERO:\t.WORD\t1" from my debugger. (the first line of my file)

string temp = RemoveWhiteSpace(data);
int i = 0;
if ( temp.length() > 0 && isalpha(temp[0]) )
    cout << "without true worked" << endl;
if ( temp.length() > 0 && isalpha(temp[0]) == true )
    cout << "with true worked" << endl;

This is my code to check if first character of temp is a a-z,A-Z. The first if statement will evaluate to true and the 2nd to false. WHY?!?!?! I have tried this even without the "temp.length() > 0 &&" and it still evaluates false. It just hates the "== true". The only thing I can think of is that isalpha() returns != 0 and true == 1. Then, you could get isalpha() == 2 != 1. But, I have no idea if C++ is that ... weird.

BTW, I dont need to know that the "== true" is logically pointless. I know.

output was

without true worked
