I'm not a C++ type person, but at line 44 where you start the if statement, there are no brackets starting and ending that. Also, I think you need brackets for the else statements too. I don't know if that is supposed to be like that though.

Re: making a simple c++ game

Well adopting a consistent approach to indentation will help, not some chaotic mix you have at the moment.
Eg.

            {

            }
        }
        break;
    }
}  

It's immediately obvious that the break; on line 52 isn't part of the switch/case.

Also, the do at line 21, which ends at 53 is missing a condition on line 53.

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.

Well did you just copy/paste it and hope it would work?

Perhaps the do on line 21 is matched by the while on line 26 ?

I think that while should be on line 53?

well i did copy/paste it. I wasn't positive it would work but it helped me know that I need to move my while to 53, but it seems to screw the loop up. I am happy to see that my Case A is working properly just that after i guess once it goes back to the menu.

Re: making a simple c++ game

A radical suggestion, instead of coding the games inside the switch, make the games functions and do something like

 Help with Code Tags 
 cplusplus Syntax (Toggle Plain Text) 
while(1)
{
    cout << "A: To Play the number guessing game." << endl;
    cout << "B: To Play the letter game." << endl;
    cout << "C: To quit program." << endl;
    cin >> choice;	
 
    switch (choice) 
    {
        case 'A': case 'a': // number guessing
            number_guessing();
        break;
        case 'B': case 'b': // letter game
            letter_game();        
        break;
        case 'C': case 'c': // exit
	    return 0;
        default:
	    cout << "Correct choice please ...\n";
        break;
    }
}
while(1)
{
    cout << "A: To Play the number guessing game." << endl;
    cout << "B: To Play the letter game." << endl;
    cout << "C: To quit program." << endl;
    cin >> choice;	

    switch (choice) 
    {
        case 'A': case 'a': // number guessing
            number_guessing();
        break;
        case 'B': case 'b': // letter game
            letter_game();        
        break;
        case 'C': case 'c': // exit
	    return 0;
        default:
	    cout << "Correct choice please ...\n";
        break;
    }
}

Or perhaps use if/else if/else ... instead of switch() .

    do{
    } while (choice != 'c' && choice != 'C');

This should be your code to start with, then you compile it to see what the result is. If it doesn't compile, then fix it.

Then your code becomes

    do{
        cout << "A: To Play the number guessing game." << endl;
        cout << "B: To Play the letter game." << endl;
        cout << "C: To quit program." << endl;
        cin >> choice;
    } while (choice != 'c' && choice != 'C');

Compile it again, and fix any new errors.

Then perhaps

Notice how you can add just a few lines at a time, and it will compile.

When you've done this a few times, then test what you've written so far to make sure it actually works as expected. If it doesn't, then fix those before adding more code.

In particular, note that the { } are never left out of place, or unbalanced.

What you've done is code beyond your ability to deal with the compiler throwing the whole mess back at you, so instead you dump it on a message board for someone else to fix. This isn't a good long term strategy.
