"Supposedly" easy program not working... With no errors

[spoodlz]

The program is as follows:

Write a program that uses four functions to do the following:
**USE ALL GLOBAL VARIABLES

1.) Ask the user for his name, age, and birthday

2.) Print his name 20 times using a DO WHILE loop

3.) Print his name, age, and birthday in the center of the screen for 5 sec.

4.) Tell the user if he is older, younger, or the same age as yourself

Here is my code:

#include <iostream>
#include <iomanip>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <windows.h>
#include <conio.h>

using namespace std;

const int NotUsed = system( "color 0a" );

void UserInfo();
void NameLoop();
void PrintCenterInfo();
void OlderYounger();

char name[20];
char birthday[20];
int age, MyAge = 17, x = 1;

int main()
{
	UserInfo();
		cout << '\n';

	NameLoop();
		cout << '\n';

	PrintCenterInfo();
                cout << '\n';

	OlderYounger();
		cout << '\n';

	return 0;
}

void UserInfo()
{
	cout << "Enter your name: ";
	cin.get(name, 20);
	cout << "Enter your age: ";
	cin >> age;
	cout << "Enter your birthday: ";
	cin >> birthday;
}

void NameLoop()
{
	do
	{
		x++;
		cout << name << '\n';	
	}
	while(x != 21);
	system("PAUSE");
}

void PrintCenterInfo()
{
        system("CLS");
	cout << name << '\n';
        cout << age << '\n';
        cout << birthday;
	Sleep(5000);
}

void OlderYounger()
{
	if(age < MyAge)
	{
		cout << "You are younger than me.";
	}
	else if(age > MyAge)
	{
		cout << "You are older than me.";
	}
	else if(age == MyAge)
	{
		cout << "You are the same age as me.";
	}
}

For some reason, it just ends at the end of the function PrintCenterInfo(). It
sleeps for 5 seconds, but it never goes back to the main() function, so it never calls OlderYounger(), or print a new line '\n'.

I tried commenting Sleep(5000); out of the program, but it does the same thing.

Can someone please help me out?

The problem could be that your console window won't stay open after OlderYounger() so you won't read the output.
If this is the problem check this out: http://www.cplusplus.com/forum/articles/7312/

Thanks Bazzy.

I checked the topic out, but there's still one thing I am confused about:

How do I know that's the problem?

And if it is the problem, where would I include any of that?

Again, thank you soo much for your help.

If that is the problem use cin.ignore( numeric_limits<streamsize>::max(), '\n' ); at the end of your program ( just before return 0; in main )

[spoodlz]

A slight problem to this is that my teacher has no idea how to use c++... Let alone how to program.

So I don't really understand

cin.ignore( numeric_limits<streamsize>::max(), '\n' );

what that does...

It is explained in the link I posted earlier: it makes the console window stay open until the user presses enter
