erm i got a bit problem with toupper();
example:
char ch = 'a';
char upper;
upper = toupper(ch);
if i use cout to show char "upper", it shows the ascii code for uppercase..
in this case, it shows '65' in screen, i know it supposed to show 'A' instead of '65', how to makes it shows 'A' instead of '65' in the screen?
