1. 130 2. 103 3. 100 4. 310. The answer is the option(1). Explanation: Here the expression a**b*a + *b uses pointer in C/C++ concept. Here a**b*a + *b means 5*(value of pointer b that is 5)*5 +(value at pointer b which is 5 again). So the result is 130. 2. What will be the output of following program?
