General menu function:

main.cpp

// Nick Fazzolari

#include <iostream>

using namespace std;

void userMenu(char menuSelection);
void printMenu();
void baseUi();
// void baseUi({params for locals in main here});

int main() {
	// My idea is to only store function calls, variables/arrays in main
	// and class objects.
	baseUi();

	return 0;
}

// this function handles the user input
void userMenu(char menuSelection) {

	switch (menuSelection) {
	case '1':
		cout << "Menu Selection '1'" << endl;
		break;
	case '2':
		cout << "Menu Selection '2'" << endl;
		break;
	case '3':
		cout << "Menu Selection '3'" << endl;
		break;
	case 'q':
		cout << "Shutting down..." << endl;
		exit(0);
		break;
	default:
		cout << "Invalid input.";
	}
}

// this function prints the avilable menu options
void printMenu() {
	cout << endl
		<< "Please make a selection: " << endl
		<< "[ 1 ] Menu selection 1: " << endl
		<< "[ 2 ] Menu selection 2: " << endl
		<< "[ 3 ] Menu selection 3: " << endl
		<< "(When done enter 'q' to quit): " << endl
		<< "Make a menu selection: ";
}

// this function gets the menu input and controls its execution
void baseUi() {
	char menuSelection;

	do {

		printMenu();

		cin >> menuSelection;
		cin.clear();
		cin.ignore(100, '\n');

		// parse user input
		userMenu(menuSelection);

	} while (menuSelection != '4');
