what is ment by 0xff and 0xaa. i can't understand these type of codes.
so please any one explain me about these type of codes.
In C as in C++ (the actual topic of this newsgroup), the syntax 0x
followed by a hexadecimal digit (or digits) denotes a hexadecimal
literal - a number written in the notation base 16. Similarly, if
there is no 'x' after the leading 0, it's an octal literal, and if
the number does not start with 0, it's a decimal literal.
In your case 0xff is 0377 or 255, 0xaa is 0252 or 170.
