    Well, each char is 1 byte, and you asked it to calculate the size of two chars

    @alwaysmpe just assume there is no returns statement in above program , then also it show same output for "" size of(a+b+c+d+e); ""

    Because although a and a are each of type char, the expression a + a is of type int. So is a + b + c + d + e. Anytime you do math with char types, they are converted to int before doing the actual calculations.
