Write a program to simulate hand-held electronic calculator. Your program should execute as follows: Step 1: display a prompt and wait for the user to enter an instruction code (a single character): ‘+’ for addition ‘-‘ for subtraction ‘*’ for multiplication ‘/’ for division ‘p’ for power ‘c’ to clear the current accumulator ‘s’ for square root ‘l’ for log ‘n’ for ln ‘q’ for quit Step 2: (if needed) display a prompt and wait for the user to enter a type float number (which we will call left-operand) Step 3: (if needed) display a prompt and wait for the user to enter a type float number (which we will call right-operand) Step 4: display the accumulated result at any point during processing and repeat steps 1 through 3 using a GOTO statement (no loops in this assignment). Use a separate function enter_code to prompt the user for instruction code and to ensure that a valid code is entered. Also, use a separate function enter_operand for the entry of the left-operand and the right-operand. Finally, use another function compute to perform the indicated operation. (unless q was entered).
