why is the flag being set to fail

after the second input it seems like the fail flag is set and it wont accept input the next time

here is the code.. really small and simple program

Code:

#include <iostream>
#include <conio.h>
#include <cstring>
using namespace std;

int main (void)
{
	int x = 0;
	char *f1,*f2,*f3;
	char f1f[20],f2f[100];
	cout << "Enter the number of loops: ";
	cin >> x;
	cout << "Enter the Computer Name: ";
	cin >> f1f;
	cout << "Type in the message you wanna send: ";	
	cin.getline (f2f, sizeof (f2f),'\n');
	f1 = new char [strlen(f1f)+1];
	strcpy (f1, f1f);
	f2 = new char [strlen(f2f)+1];
	strcpy (f2, f2f);
	f3 = new char [11+strlen(f1)+strlen(f2)];
	strcpy (f3, "net send ");
	strcat (f3, f1);
	strcat (f3, " ");
	strcat (f3, f2);
	for (int i = 0; i < x; i++)
		system (f3);
	return 0;
}

cheers

Code:

	cout <<flush<< "Enter the Computer Name: ";

actually when i added a cin.ignore () it did the job too

mackol,

If you don't already know and want to understand why you need to add cin.ignore(), click on number 4 here:
