Question

Please, I need help, I cannot figure out how to scan variables in to the function prototypes!

Input Pararmeters: 3 real numbers Output: float Task: Compute the resistance of a serial cicuit with 3 resistors and return it as main should be the first function in your program maini Declare variables as needed. -Invoke the function to display your info in a box of stars. - Prompt the user to enter 3 resistor values, read them into three float variables, r function's output. The formula is Serial Resistance = R1 + R2 R3 Assume R1, R2. R are the resistance values of three resistors: r2. 13 Prompt the user to enter the resistor value, R and the current I in a circuit. -Invoke the function to display the menu of options. a. Input Parameters: 3 real numbers b. Output: float c. Task: Compute and return the resistance of a parallel circuit with 3 resistors o Prompt the user to choose an option. Read it into an variable. Use a switc statement to process the selected option *Invoke somnuSsricaRcaistans0 passing rl, r2, r3 as input "Display the total resistance in main). *Invoke samauteParallcRcsistan0 passing rl, r2, r3 as input "Display the output in mainO. · Invoke computeVoltage 0 to compute the voltage, passng R and "Display the voltage in main. o Option-1 and return it as output. The formula is: Resistance-T R1 R2 R3 o Option-2 The Ohm's formula for calculating voltage across the resistor is: V IR. Where V is the voltage: I is the current and R is the resistance. o Option-3 a. b. c. Input Parameters: current as a whole number; resistance as a real number Output: float Task: Compute the voltage using Ohm's formula: V-IR 1nput arguments. o Option-4 Display "Program will end now." o Default: a. Input Parameters: none b. Output: void c. Task: Display Display: "Invalid Option, try again. programmer's info in a box of stars in Grading chart: Function Prototypes(0.5 a. b. c. Input Parameters: none Output: void Task: Display the menu of options. The menu is as follows: Mini Electrical Circuit Intro comments (-1 if missing) display mem Function 1) Equivalent series resistance 2) Equivalent parallel resistance 3) Ohm's Law 4) Exit

******This is what the program should look like as it runs but I cannot figure out how to successfully build the code to do such.******

Made changes to your code. so once check and run.
