[C++] Password Protected Program Using While Loop

[ksrocks333]

This short source code will show you how to make a password protected program using a while loop. If you have any questions or comments, post them here.

Source Code:

#include <iostream.h>
#include <string.h>
using namespace std;

int main()
{
    string pass;  //this is what ever you set your password to
    
    cout<<"This program is password protected. Enter the password: ";
    cin>>pass;
    while(pass!="qwerty123") //sets a loop, so while they don't put the password in as qwerty123 (or whatever you set yours to)
    {                            //then the program wont start, it will just give an error message.
         cout<<"That is not the password, the program will not start until you get the password right."<<endl;
         cout<<"Try again: ";
         cin>>pass;
    }
    
    cout<<"Access Granted, program will now start."<<endl;
    
    // the rest of your program would go BELOW this while loop. Make sure it's after the while loop.
    // the while loop is basically outputting the message until the condition is broken.
    // if you had your program before the loop, it would still go through and not see the while loop until after the program.
    
    //That's how you make a password protected program using a while loop.
    
    system ("PAUSE");
    return 0;
