In Microsoft Visual Studios:

Write a C program that evaluates the equations provided below. The program must prompt the user for inputs to the equations and evaluate them based on the inputs. All variables on the right hand sides of the equations must be inputted by the user. All variables, except for the plaintext_character, encoded_character, and variable a are floating-point values. The plaintext_character and encoded_character variables are characters, and the a variable is an integer. The constants used in the equations must be defined as constant macros (#defined constants). Error checking is not required for your program. You do not need to check for faulty user input or dividing by zero.

result should be simiar to this:
