User should be prompted to enter two non-negative numbers (say, a and b where a >0 and b > 0) line by line and then press the enter key. Your program should calculate and display the following for these numbers (see sample output below): Sum (a + b) Difference (a - b or b - a, whichever gives a positive value) Product (a x b) Power (ab) OUTPUT Num1: 2 Num2: 10 Sum = 12 Difference = 8 Product = 20 Power = 1024 Num1: a Invalid Number Num1: x End of program
