I need help with part B for this lab completed below is the starter code given to help us:

	// Ohms law structure assignment - part a starter code
	//
	// This code solves the basic case of one resistor and one voltage source
	//
	// Please convert this starter code to use functions as much as possible
	// It will become part A of the laboratory
	//
	// You need to create at least 5-functions
	#include iostream>
	#include string>
	#include vector>
	using namespace std;
	// You must use this structure
	struct node {
	string name;
	double resistance;
	double voltage_across;
	double power_across;
	};
	// An Example of the type of function you may want to create
	string nodeName() {
	string node_name;
	cout "Enter Node Name: ";
	cin >> node_name;
	return node_name;
	}
	//
	// The comments indicate good places to covvert code to short functions
	//
	int main() {
	node N1;
	// Enter source voltage
	double source_voltage;
	cout "Enter Source Voltage: ";
	cin >> source_voltage;
	// Enter basic Node Information
	N1.name = nodeName();
	cout "Resistor Value: ";
	cin >> N1.resistance;
	// Calculate series current for the one-node network
	double total_resistance = N1.resistance;
	double series_current = source_voltage/ total_resistance;
	// Calculate voltage across the restistor
	N1.voltage_across = series_current * N1.resistance;
	// Calculate the power across the resistor
	N1.power_across = N1.voltage_across * series_current;
	// Display Network Information
	cout "Series Network: "
	cout "Source Voltage: " "-Volts"
	cout "Total Resistance: " "-Ohms"
	cout "Series Current: " "-Amperes"
	// Display Node information
	cout "Node Name: " name
	cout "Node Voltage: " voltage_across "-Volts"
	cout "Node Resistance: " resistance "-Ohms"
	cout "Node Power: " power_across "-Watts"
	return 0;
	}

Obiective: To create a series DC circuit solver that involves voltage, current, resistance, and power. It will use Ohm's law to determine the voltage, power, and current through individual resistors Laboratorv Checklist: Review Ohm's law. See last page in the document . Review C++ Functions o Review C++ Vector class Read Problem Specification Download the starter code Please create and implement a simple series circuit solver for one resistor. Use the filename of ohms-part-a.cpp for GITHUB.UC.EDU submission. Please create and implement a series circuit solver that can take an "unlimited" number of resistors by utilizing the C++ "vector" class. Use the filename of ohms-part-b.cpp for GITHUB.UC.EDU submission Parts B needs to be checked by Teaching assistant or instructor during your assigned laboratory session Please add a menu to your series circuit solver to allow for deleting nodes (resistors) in your circuit, display the calculated results, allow for adding nodes (resistors) to your circuit, and changing input voltage. Use the filename of ohms-part-c.cpp for GITHUB.UC.EDU submission When complete push assignment related files to GITHUB under lab folder containing ohms-part-a.cpp, ohms-part-b.cpp and ohms-part-c.cpp . . Specification This assignment is divided into three parts one is a simple implementation of a series DC circuit (a voltage source, resistance, and current plus power calculation). Part B will use the vector class to "unlimit" the number of resistors in the circuit. Part C is to create an edit menu so you can make changes to vour circuit Please use this structure to store the information related to each node in your series DC network
