After 2 days of C++

Well my first project after 2 days of C++, any c&c appreciated.

Oh and I know using system() is bad programming.

Code:

/*
========================
-----Calculator V1------
========================
- Created in Visual C++ - 
========================
*/

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

//Multiplication declarations, definitions later in the program
void Adding(int FirstNumber, int SecondNumber);
void Subtracting(int FirstNumber, int SecondNumber);
void Division(int FirstNumber, int SecondNumber);
void Multiplication(int FirstNumber, int SecondNumber);

int main()
{
	int FirstNumber, SecondNumber;
	SecondNumber = FirstNumber = 0; //Must be valued to something
	int ChoiceMenu;
	char PlayAgain;
	do{ //Start of do-loop
		system("CLS"); //Once the loop runs again the previous text will be cleared
		cout<<"====================="<<endl;
		cout<<"--- Calculator V1 ---"<<endl;
		cout<<"====================="<<endl;
		//Startup-Menu
		cout<<"Menu (1-5)"<<endl;
		cout<<"1) Adding"<<endl;
		cout<<"2) Subtracting"<<endl;
		cout<<"3) Division"<<endl;
		cout<<"4) Multiplication"<<endl;
		cout<<"5) Quit"<<endl;
		cin>>ChoiceMenu; 

		switch(ChoiceMenu)
		{
		case 1:
			Adding(FirstNumber,SecondNumber);
			break;
		case 2:
			Subtracting(FirstNumber,SecondNumber);
			break;
		case 3:
			Division(FirstNumber,SecondNumber);
			break;
		case 4:
			Multiplication(FirstNumber,SecondNumber);
			break;
		case 5:
			return 0;
		}
		cout<<"Do you wish to use again (Y/N)?\n";
		cin>>PlayAgain;
	}while(PlayAgain == 'y' || PlayAgain == 'Y'); //If user inputs "Y" or "y" then loop continues, else it breaks

} //End of do-loop

void Adding(int FirstNumber, int SecondNumber)
{
		system("CLS");
	cout<<"--------------------"<<endl;
	cout<<"----- ADDITION -----"<<endl;
	cout<<"--------------------"<<endl<<endl;
	cout<<"Enter your first number\n";
	cin>>FirstNumber;
	cout<<"Enter your second number\n";
	cin>>SecondNumber;
	cout<<endl;
	cout<<"Calculating........."<<endl<<endl;
	cout<<"-------------------------------------------------------------------"<<endl;
	cout<<FirstNumber<< " + "<< SecondNumber<< " = "<< FirstNumber+SecondNumber<<endl;
	cout<<"-------------------------------------------------------------------"<<endl<<endl<<endl;
}
void Subtracting(int FirstNumber, int SecondNumber)
{
		system("CLS");
	cout<<"--------------------"<<endl;
	cout<<"----- SUBTRACTION -----"<<endl;
	cout<<"--------------------"<<endl<<endl;
	cout<<"Enter your first number\n";
	cin>>FirstNumber;
	cout<<"Enter your second number\n";
	cin>>SecondNumber;
	cout<<endl;
	cout<<"Calculating........."<<endl<<endl;
	cout<<"-------------------------------------------------------------------"<<endl;
	cout<<FirstNumber<< " - "<< SecondNumber<< " = "<< FirstNumber-SecondNumber<<endl;
	cout<<"-------------------------------------------------------------------"<<endl<<endl<<endl;
}
void Division(int FirstNumber, int SecondNumber)
{
		system("CLS");
	cout<<"--------------------"<<endl;
	cout<<"----- DIVISION -----"<<endl;
	cout<<"--------------------"<<endl<<endl;
	cout<<"Enter your first number\n";
	cin>>FirstNumber;
	cout<<"Enter your second number\n";
	cin>>SecondNumber;
	cout<<endl;
	cout<<"Calculating........."<<endl<<endl;
	cout<<"-------------------------------------------------------------------"<<endl;
	cout<<FirstNumber<< " / "<< SecondNumber<< " = "<< FirstNumber/SecondNumber<<endl;
	cout<<"-------------------------------------------------------------------"<<endl<<endl<<endl;
}
void Multiplication(int FirstNumber, int SecondNumber)
{
		system("CLS");
	cout<<"--------------------------"<<endl;
	cout<<"----- MULTIPLICATION -----"<<endl;
	cout<<"--------------------------"<<endl<<endl;
	cout<<"Enter your first number\n";

	cout<<"Enter your second number\n";
	cin>>SecondNumber;
	cout<<endl;
	cout<<"Calculating........."<<endl<<endl;
	cout<<"-------------------------------------------------------------------"<<endl;
	cout<<FirstNumber<< " * "<< SecondNumber<< " = "<< FirstNumber*SecondNumber<<endl;
	cout<<"-------------------------------------------------------------------"<<endl<<endl<<endl;
}

 

This Has An Error With Directory

 

What compiler are you using?

 

Yeah...C++ is to confusing for me. I'll stick with my c# Lol.

 

Good work with the switch

 

Yea Calculator is very fun to make xD
Good Job on it

 

Dev C++

 

Your an idiot, l2 program.

 

What!?

 

You're a troll, learn to be a decent human being.

 

to be brutally honest this thread only attracts retards because the OP is itself retarded.
regardless, have you never heard of function pointers and arrays?

 

nice job = ) , i took Intro to C++ then i learned JaVa and now i mostly use java but C++ is fun too.

 

he said its been 2 days -.- You wouldn't learn that in the first 2 days of C++ programming. Nice job in programming though.

 

Decent work for 2 days...when I first started I focused on actual computing rather than time-consuming decorations with cout...lol. Oh, and you don't need all those cout's, as one cout for each block of text will suffice.

Anyways, I think you're trying to do too much too fast. You probably want to focus on if's then while's/do-while's then for's. Making that calculator makes use of a switch (which is an if-else) and a do-while, but I don't think you quite understand them yet. Some great ways that I learned about for's and if's was by sorting numbers (either a set number or any amount), testing for prime numbers, or printing out tables (try a multiplication table).

Nice job, but I think you're trying to go too fast...you should probably do some problems with if's before you even get to loops...

 

Good job for 2 days, but I'd like to tell you this: never, ever, ever use system calls.

 

Nice for 2 days
may i ask who taught you?
