How do you compare characters in c plus plus?

Answer 1

Characters are simply character codes, so they can be compared just like any other value. They can also be compared using literal character constants. The compiler will replace character literals with their equivalent character codes.

char c = 'a'; // variable c is 0x61 (hex) or 97 (decimal).

if( c 97 ){...} // true, 'a' is character code 97 decimal.

if( c > 'b' ){...} // false, 'a' is not greater than 'b' (that is, 97 is not greater than 98).
