    How do you input the Hex value? From a file/user? In what format?
    If it not from file/user or other IO, then it is in the memory. That means it is in binary format. If it is then it just characters.

    first figure out which end is high and which end is low, then read a reference for bitwise operators.

    Not sure what you mean, but if your values are stored in memory, then AND'ing will get you the desired effect.

    Code:
    //check if 8th bit is set
    if(randomValue & 0x80)
    { //do stuff }

    hey look at that, the top hit for "c++ bitwise operators" is a link on this very site!
