One of the best books for ppl new to C is "Learn C on the Macintosh" by Dave Mark. He takes baby steps and explains all the basic concepts first even if you plan to use C in other platforms.

Modulus ( the absolute value ) of a real number is its numerical value without regard to its sign.

abs(5)=5
abs(-5)=5


And the modulo operation (%) finds the remainder of division of one number by another.

5%2=1
