1.5.1 Postfix

Postfix operators are operators that are suffixed to an expression.

operand++;
This causes the value of the operand to be returned. After the result is obtained, the value of the operand is incremented by 1.

operand--;
This is the same but the value of the operand is decremented by 1.

Examples:

int joe=3;
joe++;

The value of joe is now 4.

printf("%i",joe++);

This outputs the number 4. The value of joe is now 5.
