Himanshu  (9 years ago)

++ and -- are increment and decrement operator respectively...
They can be used with only variables like i .
suppose i=5;
i++ will result in 6
i++ will resullt in 4

But, printf("%d %d",i++,i--); can result in Undefined Behaviour.. So be careful in using ++ and -- oprtaor.
Moreover,
5++ will give Compile error.
