Noobie ?

hey guys!! First of all I hope there isn't a post like this, if so sorry for making a new one!! I'm a new programmer and I'm teaching myself C++ and i'm making a Enter password program that will print out "Password is correct"!! if user entered it correctly, and if the user doesn't enter it correctly then it automaticly starts the program over and gives the user 3 trys. If the users doesn't get it in 3 trys the it print out " Try again later!!" then closes the program!! This is all I have so far!!

Code:

 #include <iostream>
using namespace std;
int main ()
{
    
    string password = "03j14a86c";
    string UserInput;
    
        cout << "Please inter your password!!" << endl;
        
        cin >> UserInput;
        
if (UserInput == password)
{
              cout << "Password is correct!!" << endl;
              }
              
              else 
              {
                   
                   }
                   
                   return(0);

thanks for any help!! Jake

sorry I have looked at your link but I still can't get it to do right. I'm getting it to run but its not doing right. Can you show me how? Here is an update of my code:

Code:

  #include <iostream>
using namespace std;
int main ()
{
    
    string password = "03j14a86c";
    string UserInput;
    
        cout << "Please enter your password!!" << endl;
        
        cin >> UserInput;
        
if (UserInput == password)
{
              cout << "Password is correct!!" << endl;
              }
              
              else 
              {
                   cout << "Password not correct!!" << endl;
                   }
                   
                   for ( int x = 1; x <= 3; x++);
                   {
                         }
                         
                         cin.get();
                         cin.get();
                   return (0);

Start by making a flowchart. Mesh out the logic on how you want to approach this.
A little better indentation wouldn't hurt, either.
Oh, and don't use semicolons after for loops, or any other kind of loop.

Ok so first of all you don't need to define the password as a string and then make the comparison, it's kind of a waste of code, unless you are going to use it somewhere else. You're better off comparing it right away. Eg:

Code:

 If (UserInput == "03j14a86c")

2) Instead of

Code:

 cin >> UserInput

, try

Code:

 getline(cin, UserInput)

That way, the whole lne will be "read" and your program won't assume you inserted 2 passwords in case you insert a space while typing it.

3) In order to provide the user with 3 tries, you need to make a loop. Personally I'm used to while loops in this kind of situations. Eg:

Code:

while(NumberOfTries != 3)
{   
    if(/*Your comparison*/)
   { 
       cout << "The password is correct";
       break;   
   }
}

Now add yourself what you think that should be added in order to make it work.

Don't hand out solutions. If the OP cannot figure out how to make a simple loop, the OP cannot do programming.
That is why the OP must be taught on how to make loops, which usually accounts to seeing how to connect the logic, which flowcharts helps with. Simply saying "do this and that" will not help the OP see HOW to construct loops in general.
