Loop a set number of times.

[Ed96]

I have been trying to make a program that asks for username and password, and if it is wrong it will loop back to the top. But i only want it to loop a set number of times, how can i do this?
this is my code so far

string username;
string password;

cout << "Enter username: ";
getline(cin, username, '\n');

cout << "Enter password: ";
getline(cin, username, '\n');

if (username == "1" && password == "1"){
cout << "Success, you made it!" << endl;
}

else {
cout << "Access denied" << endl;
}

Well this is were boolean variables comes in handy:

#include <iostream>
#include <string>

using namespace std;

int main()
{
	bool success;
	string username;
	string password;

do
{
	cout << "Enter username: ";
	cin>>username;

	cout << "Enter password: ";
	cin>>password;

	if (username == "ron" && password == "secret")
	{
	cout << "Welcome Ron!\n";
	success = true;
	}
	else
	{
	cout<<"Login Failed - Please try again.\n";
	success = false;
	}
} while (!success);

return 0;
}

and if you want to loop only a set amount of times, then add a counter.

make a 'tries' variable, increment it everytime the user enters his username or password, if he enters the wrong username or password more that 'certain amount of times' then break out of the loop.

string username;
cin>>username;
string password;
cin>>password;
++tries;

if ( tries >= 3 )
{
cout<<"Login limit exceeded , please try again in 10 minutes"<<endl;
//blah blah blah
}
