int c=- -2;

main()

{

    int c=- -2;

    printf("c=%d",c);

}

Answer:

                      c=2;

             Explanation:

Here unary minus (or negation) operator is used twice. Same maths  rules applies, i.e. minus * minus= plus.

Note: However you cannot give like --2. Because -- operator can  only be applied to variables as a decrement operator (eg., i--). 2 is a constant and not a variable.
