Question

Problem: Design and write a C language program that can be used to calculate Voltage, Current and Total Resistance for a Series or Parallel or a Series Parallel circuit. The program should display the main menu that contains the three types of circuit calculations that are available and then the user will be prompted to select a circuit first. After the circuit has been selected the program should then display another menu (i.e., a submenu) requesting the necessary data for the particular circuit calculation. EXAMPLE: For a series circuit, given the voltage and the individual resistors you will calculate the total resistance, the total current and the voltage across each resistor. The program will compute and display the results. The program will then prompt the user to return to the main menu and repeat the same process, or terminate the program. Program requirements: You must use separate user-defined functions for your • program explanation (for the user) • menu • to receive the data • to calculate your results • to print your results You must also include a programmer's block at the top of your code and your program must include: • Loops • Decisions Hand in the following: Program documentation should contain the following: · Signed cover page . Problem description (This document) • Program algorithm (pseudocode or Structure Diagram(preferred)/flowchart) · Printout of the source code Samples of the program output
