    unsigned int or unsigned long, I'd guess.

    Hexadecimal is just a way to represent a number, as is decimal and binary.

    0x0F == 15 == 00001111

    It's all the same thing. Deep down, the computer treats all numbers as binary, but it doesn't really matter. Numbers are numbers.

    If you want to declare a number in hex, just do it, using any data type that you want.

    Code:
    char c = 0x0A; /* 0x0A = 10 = '\n' */
    Code:
    int x = 0xF0000000; /* Will be taken as a negative number because the sign bit is one.
    				If you declare x as an unsigned variable,
    				then it will be taken as a positive number */
