1. Prompt the user for one of the arithmetic operators ('op'): +, -, *,/, or ** 2. Prompt the user for two input integers ('a' and'b') 3. The input numbers can be positive or negative 4. Perform the arithmetic operation using the two input numbers 5. The first entered number ('a') is the left side, the second ('b') the right side of the operation For exponentiation, the first number is the base, the second the exponent Print (display) the following messages (but not the quotes), including the prompts Start of Calculator Program" "Enter the desired operation (+,-, *, /, **): "Enter the input number: " "Enter the second input number: - " "End of Calculator Program" 6. -", use the following examples as a guide (the output hould look like the example sin the second column) Calculation (op, a, b +, 12, 9 The print (displav) output: 12 +9-21 18-26--8 25 * 6 150 96/ 32 = 3.0 5**3- 125 18, 26 *, 25, 6 /, 96, 32 Don't worry about the exact spacing and formatting of the output numbers. The floating point umbers, for example, might have more digits to the right of the decimal point. We'll learn how to
