"Skip" Problem? [Solved]
So I just started learning C++, and I figured the best way to remember / figure out new things is to practice. So, I was going to build a simple calculator. But I have a problem >_< here's the code so far. And I know it is un-organized, but I was trying to remove spaces and do stupid things to desperately make it work..

(ONLY _ADD() IS FINISHED)
Code:
#include "stdafx.h"
#include <iostream>

using namespace std;

//Global Variables

	int x;
	int y;
	int userAnswerX;
	int userAnswerY;

	int userChoice;

//Global Variables

int main()
{
	cout << "===================\n";
	cout << "=    Calculator   =\n";
	cout << "===================\n";
	cout << "1) Add\n";
	cout << "2) Subtract\n";
	cout << "3) Multiply\n";
	cout << "4) Divide\n";
	cout << "(Type the number)\n";
	
	cin >> userChoice;

		if (userChoice==1) _add();

			if (userChoice==2) _subtract();

				if (userChoice==3) _multiply();

					if (userChoice==4) _divide();
						
						else (system("pause>nul"));

}


int _add ()
{
	cout << "\nEnter value for X: ";

	cin >> userAnswerX;

	x = userAnswerX;

	cout << "\nEnter value for Y: ";
	
	cin >> userAnswerY;

	y = userAnswerY;

	cout << "\nYou set X equal to ";
	cout << x;
	cout << "\nYou set Y equal to ";
	cout << y;
	cout << "\n \n";
	
	cout << x + y
	
	system("pause>nul");
}

int _subtract ()
{

}

int _multiply ()
{

}

int _divide ()
{

}
Here is a SS of what happens when I first build / run:



Here's what SHOULD happen:

Code:
================
=  Calculator  =
================
1) Add
2) Subtract
3) Multiply
4) Divide
(Type the number)

"User types number here"
( Goes to _add(), _subtract(), _multiply(), or _divide() )
Sorry if I wasn't perfectly clear, feel free to ask questions.

Don't post the screenshot as an attachment.. post it like this [img]Your screenshot link[/img] When I see the picture I can assist you a bit more.
Are you saying that when you run your calculator it doesn't skip lines ?

Sorry, didn't realize what else you said. The problem is it IS skipping lines. It skipped everything after ==== Calculator ==== and went strait to _add()

Sure that'll work.

So you want

Code:
	cout << "===================\n";
	cout << "1) Add\n";
	cout << "2) Subtract\n";
	cout << "3) Multiply\n";
	cout << "4) Divide\n";
	cout << "(Type the number)\n";
to appear before
Code:
Enter value for X

Exactly, I'm not even sure how it skipped in the first place...it should prompt the user to enter 1 - 4, then afterwards, I have an array of "IF's", each leading to different functions. Entering anything but 1 - 4 will pause, then exit the program.


I can't even tell if I made a noob move, I see nothing wrong within the main() function...

#include "stdafx.h" wasn't needed here. The program compiles perfectly fine. Anyways, have fun !!

Mine had a fatal error until I added it D: Probably different compiler or something...Dunno, but either way, thanks.

Yeah, I guess so. I am using Visual Studio 2010.
Anyways, Marked Solved.

Anytime, & if you want some credits at the end do something like

Code:
cout<<"yourcalculatorname,Developed  by BobFM\n";
Code:
cout << "Copyright© 2011 " << endl;
Or something in that sort.
