    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
