Develop a simple calculator program that reads two positive integer numbers a & b and then prompts the user to enter an operation char as follows:

Calculator operations:

Enter A for addition (a+b)

S for subtraction (a-b)

M for multiplication (a*b)

D for division (a/b)

R for remainder (a%b)

F for factorial of the sum of a and b

W for the power of a to b

Q for square root of the product of a and b.

E. for sum of even numbers in range

O. for sum of odd numbers in range

P   for sum of prime numbers in range

V for reversing digits of the smaller of a and b (ex: 654 reverses to 456)

X for exit

• Program should keep running until user enters X.
• If the user enters any other code, the program should output a message indicating that character entered is not within the list, then it displays the list again.
• If the user enters a negative number for either a or b, the program should use it’s absolute value
• The program should be structured with at least five value returning functions ( F, E,O,P,V) along with main program
