cpp

char letter1 = 'a'
char letter2 = 'B';

letter1 = letter1 - 32; //will convert 'a' to 'A'
letter2 = letter2 + 32; // will convert 'B' to 'b'

Whenever this topic (converting case) comes up I send people over to www.asciitable.com.

There are several ways that you can convert cases, one way is your use a conditional block (if-else-if or switch etc). The other way is to use a little math (see letthecolorsrumble post).

I agree. This is the easiest way to do it. Just don't forget to #include <ctype.h> in your preprocessor directives.

So store the result somewhere else.

CODE

char foo = 'a';
char bar;

bar = toupper(foo);

cout << foo << endl << bar << endl;


First week of CS kind of stuff.

missy if you want to change an uppercase letter to lowercase just use the tolower function()...okie
i hope i may gonna help you...
goodluck!!!

CODE
//Example reads in a character and makes up lowercase
#include <iostream>//library for cout
#include <cctype>//librabry

using namespace std;//standard

int main()
{
    char x;//declaration variable for x
    cin>>x;//input the x
    x=tolower(x);//it will lowercase the uppercase letter
    cout<<x;//it will display the lowercase letter
}

Mod Edit: added code tags: code.gif
