I want to reinitiate my selection menu

[apox01]

Hello, I am doing a project mainly using functions and the if else statement (its what I have learned so far) and I am to get user input and simply do some math depending on what operators they picked. The code below seems a bit redundant but I am using everything I have covered up until now, so excuse my noobish ways.

So far I have like a menu
1) Add
2) Subtract
3) Divide
4) Multiply

User selects an option, they input 2 numbers, I calculate and print it on the screen. My code works fine, and I got it to do what I wanted but once the calculation is over, I want to clear all the text on the prompt and have the user see only the menu selection again incase they want to process another option. Thing is I have no idea how to reinitiate these menus, do I have to call main again?

Here is my code

// Project1.cpp - main focus is calling functions and if else statement

//Header files
#include "stdafx.h"
#include <iostream>
using namespace std;

void funcDiv()
{
	//Variables declared
	int firstNum;
	int secondNum;
	int totalAmt;

	 //DIV header display
	cout << "//////////" << endl;
	cout << "//Divide//" << endl;
	cout << "//////////" << endl;
	cout << endl;
	
	//user input - DIV
	cout << "Enter the 1st number you want to divide: ";
	cin >> firstNum;
	cout << "Enter the 2nd number you want to divide: ";
	cin >> secondNum;

	//calculate user input and print
	totalAmt = firstNum / secondNum;
	cout << firstNum << " / " << secondNum << " = " << totalAmt;
}

void funcMulti()
{
	//Variables declared
	int firstNum;
	int secondNum;
	int totalAmt;

	 //Multi header display
	cout << "////////////" << endl;
	cout << "//Multiply//" << endl;
	cout << "////////////" << endl;
	cout << endl;
	
	//user input - Multi
	cout << "Enter the 1st number you want to multiply: ";
	cin >> firstNum;
	cout << "Enter the 2nd number you want to multiply: ";
	cin >> secondNum;

	//calculate user input and print
	totalAmt = firstNum * secondNum;
	cout << firstNum << " * " << secondNum << " = " << totalAmt;
}

void funcSub()
{
	//Variables declared
	int firstNum;
	int secondNum;
	int totalAmt;

	 //SUB header display
	cout << "////////////" << endl;
	cout << "//Subtract//" << endl;
	cout << "////////////" << endl;
	cout << endl;
	
	//user input - SUB
	cout << "Enter the 1st number you want to subtract: ";
	cin >> firstNum;
	cout << "Enter the 2nd number you want to subtract: ";
	cin >> secondNum;

	//calculate user input and print
	totalAmt = firstNum - secondNum;
	cout << firstNum << " - " << secondNum << " = " << totalAmt;
}


void funcAdd()
{
	//Variables declared
	int firstNum;
	int secondNum;
	int totalAmt;

	//ADD header display
	cout << "///////" << endl;
	cout << "//Add//" << endl;
	cout << "///////" << endl;
	cout << endl;
	
	//user input - ADD
	cout << "Enter the 1st number you want to add: ";
	cin >> firstNum;
	cout << "Enter the 2nd number you want to add: ";
	cin >> secondNum;

	//calculate user input and print
	totalAmt = firstNum + secondNum;
	cout << firstNum << " + " << secondNum << " = " << totalAmt;
}

int main()
{
	//Variables declared
	int operatorSelect;

	//setting bg and text color
	system("color 02");

       //Main header display
	cout << "//////////////////////" << endl;
	cout << "//Calculator Program//" << "    Programmed by: Dee" << endl;
	cout << "//////////////////////" << endl;
	//selection menu
	cout << endl;
        cout << "[1]Add" << endl;
	cout << "[2]Subtract" << endl;
	cout << "[3]Multiply" << endl;
	cout << "[4]Divide" << endl;
	cout << "What would you like to do? (1-4) ";
	cin >> operatorSelect;

	//function calls according to user selection
	if (operatorSelect == 1)
		funcAdd();
	else
		if (operatorSelect == 2)
			funcSub();
		else
			if (operatorSelect == 3)
				funcMulti();
			else
				if (operatorSelect == 4)
					funcDiv();

	char ps;
	cin >> ps;
	return 0;
}

take a look at loops, you should be able to figure it out from that, you could call main if your compiler allows doesn't stop it, but it isn't standard c++ and shouldn't be used.

[long double main]

About clearing the screen, see this:
http://www.cplusplus.com/articles/4z18T05o/

You're technically not allowed to call main() anywhere in your program.
So don't do it!

If you want to go back to displaying the menu, you'll have to use a loop. (I hope you learned those?)

I see, its something extra I wanted to add to the project but it wasn't asked for. The next couple videos I am watching do go into the loops but I am still messing around with functions till I feel positive to go on to the rest. At least I know I will soon be able to code this into my program if I learn loops.

Thanks for the link to the article about clearing the screen, much appreciated!
