write a C plus plus program

PROBLEM STATEMENT Wye delta transformation is a one of important tool in basic circuit analysis. Based on circuit in Figure 1, develop a C++ program that uses modular programming approach and capable to perform as described in Table 1. R w R2 RA R R 2 4 (Note: All resistors value are measured in ohm.) Figure 1 Wye Delta Transformation Table 1: Menu in the WyeDelta Transformation program Action taken Selection WD Conversion Wye to Delta Prompt the user to enter each resistor's value in Wye network. Then, perform conversion to compute of each resistor in the network and display the result by calling a programmer-defined function named Wye Delta DW Conversion Delta to Wye. Prompt the user to enter each resistor's value in Delta network. Then, perform conversion to compute of each resistor in the Y network and display the result by calling a programmer-defined function named Delta2 Wye Exit the program. Before the program actually performs the exit, the program should be able to ask the user to confirm their selection. If they choose to proceed with the exit request, then the program exits. Otherwise, the program should be able to display the menu of selection to perform the WyeDelta Transformation program In addition to the above requirements, your program should be: allow to accept selection input in lowercase or combinational-case to perform suitable action. For example, the program is able to execute conversion Wye to Delta if the user enters wd (lowercase) or Wd or WD (combinational-case) for the WD selection. able to detect any invalid selections, inform the user about it and receives new input to replace the invalid input
