as follows:
Create a function named menu that has no parameters and returns a character. The function
displays the following options:
- R to calculate series resistance (R = R1 + R2).
- P to calculate parallel resistance (1/R = 1/R1 + 1/R2).
- T to calculate series capacitance (1/C = 1/C1 + 1/C2).
- S to calculate parallel capacitance (C = C1 + C2).
- V to calculate voltage across a resistor (V = I x R).
- C to exit.
The function menu should be displayed at the beginning of the program and every time a menu
option is carried out (redisplay the menu to do more calculations). The menu function should
return the user choice to main.
Create a function named validate that has no parameters and that returns a float. The function
repeatedly asks the user for a value until a positive nonzero value is entered, then the function
returns that value.
Create a function named superman that accepts two float parameters and returns a float. This
function returns F ( F = F1 + F2).
Create a function named batman that accepts two float parameters and returns a float. This
function returns F ( 1/F = 1/F1 + 1/F2). (Calculate for F)
Create a function named robin that accepts two float parameters and returns a float. This
function returns the product of the two parameters.
After the user selects any of the above options, ask the user for a float value using the function
validate and assign the return of the function to a float variable name v1 in main. Ask the user
for another float value using the function validate and assign the return of the function to a
float variable name v2 in main.
For Option R: Call the appropriate function (either superman or batman) on the values stored in
v1 and v2. Output the return of the function with the values in v1 and v2 in a formatted
statement such as: The series resistance of 2.7 ohms and 5.1 ohms is 7.8 ohms.
