What's the code to exit a programme if i request the user to press any key to exit...

with conditon : You are not allowed to use any other libraries except iostream

[Sadaiy]

create a program

then a loop

have the loop keep looping until user inputs a value

then end loop

then end program

thats it

Do you mean they must type something, press enter, and then the program ends, or they simply press any key to end the program?

I'm sure there are more ways to do it, but this is very simple and it works. ( system("Pause") is not very good, but my instructors have pretty much required it in my classes)

int main()
{
system("Pause");
return 0;
}

That will simply exit whenever they press a key.

This one requires them to type something before pressing enter, then the program exits:

int main()
{
cout<<"Enter something: ";

getchar();

return 0; //exit now
}

Is it like this?

#include <iostream>
using namespace std;

int main ()
{
	char n;
	
	do
	{ 	cout << "bla bla";
	
		cout << "Press n to exit or any key to continue";
		cin >> answer;
		cout << endl;
	}
	while ( answer != 'n' || answer != 'N' );
	
	if ( answer == 'n' || answer == 'N' )
	{
		cout << "Press a key to continue";
		getchar ();
		return 0;
	}
	return 0;
}

but the complier said no such direction or file

first of all, I'm preeeetty sure getchar() is in stdio.h. Try cin.get().
