It seems there are missing braces { } around the statements to be controlled by the if statements.

The first one,

if(userchoice == "admin")
    getch();

only the single statement getch(); is controlled by the if, that control block ends there. Later there is an else, but because there is no corresponding if, it is unmatched.

With the braces added, it would look like this:

    if (userchoice == "admin")
    {
        getch();
        cout << "Write Your Password" << endl;
    }   
    else
    {
         cout << "Invalid Input"<<endl;
         getch();
         exit(0);
    }
