Objective-C supports the following compound assignment operators:
Objective-C supports the following compound assignment operators:
−Operator Description
−x += y Add x to y and place result in x
−x -= y Subtract y from x and place result in x
−x *= y Multiply x by y and place result in x
−x /= y Divide x by y and place result in x
−x %= y Perform Modulo on x and y and place result in x
−x &= y Assign to x the result of logical AND operation on x and y
−x |= y Assign to x the result of logical OR operation on x and y
−x ^= y Assign to x the result of logical Exclusive OR on x and y

Another useful shortcut can be achieved using the Objective-C increment and decrement operators (also referred to as unary operators because they operate on a single operand). As with the compound assignment operators described in the previous section, consider the following Objective-C code fragment:

Clearly 10 is less than 20, resulting in a true evaluation of the x < y expression. The following table lists the full set of Objective-C comparison operators:
