A couple C symbols I don't understand......

[couch potato]

First off, I learned that a % is a modulus?? whats a modulus do?

Another thing, I know what it means to, say, put this:

score++;

in a program, but what does this:

score += 10;

mean?

thanks

Modulus is the remainder doing integer division.

5 % 3 = 2 (since 5/3 = 1 remainder 2)

variable += x;
is just "shorthand" for variable = variable + x;

sooo score += 10; is score = score + 10;
