Thread: How to compare two characters???

i have a question here...
How do I compare two characters?

i.e.

Code:

    char rep1, rep2;

    scanf("%c %c", &rep1, &rep2);
    
    
    if('rep1' == 'rep2')
              printf("Hello\n ");

what's wrong with the statement?

And how do I write that code if i want to print "Hello"
if rep1 == rep2 ??? they are Characters!!

thanks

I've tried....it doesnt work

iMalc is right, lose the single quotes.

Also you should be getting compile warnings with the way you had it originally.

Actually dropping the single quotes is the correct thing to do.

Where do you get the idea that you can't compare char's? It is perfectly legal.

If you still do not have this working? How are you compiling this? Are you actually giving arguments to your executable once compiled and hopefully without any warnings like "multi-character constant" or something like that.

it gives me the warning sign

"multi-character character constant"

are you sure you recompiled?

try
b='b';
a='a';
if (a==b)
