Hello all. I am new to C++ and still learning it, when you see this code you will understand. I am learning how to code using Beginning C++ Game Programming and have reached Chapter 3. At the end of Chapter 2 a "Guess my number" game is created with the exercise to create a version where the computer guesses the players number. I have since then done a very crude one and have added it to the original program. But I would like to add a play again feature at 3 different points. 1 for each type of game and one to get back to the menu. What is in the code is basically what I know so far. (Random numbers are so cool) Heres the code: #include <cstdlib> #include <iostream> #include <ctime> using namespace std; int diff; int theNumber; // The random number for the guess the computer game int tries = 0, guess, comptries = 0; //players tries = tries, guess = players guess, comptries= computers tries int choice, game; //choice = N/A, game = game selection char again = 'y', n, answer, y; // again = play again, y/n etc = answers to questions, answer game selection answer int compguess; // computers guess int main() { srand(time(0)); //seed random number generator cout << "Hello and welcome to Guess My Number version 1.5" <<endl; cout << "\nNew to version 1.5 is the option of games" << endl; cout << "To have the computer guess your number press 1" <<endl; cout << "To guess the computers number press 2 "; cin >> game; cin.ignore(); switch (game) // First menu, Game Selection { case 1: //If option 1 is selected cout << "\n\nYou have selected for the computer to guess your number" <<endl; cout << "Please think of a number between 1 and 100, then press enter" <<endl; cin.get(); do { compguess = rand() % 100 +1; comptries ++; cout << "\nIs you number " << compguess << "? Y/N "; cin >> answer; cin.ignore(); if (answer == 'n') cout << "Darn it! :(" <<endl; } while (answer != 'y'); cout << "\nHaha I guessed you number in " << comptries << " tries"; cout << "\n\nPress enter to close, keep an eye out for 1.6" <<endl; break; case 2: // If option 2 is selected cout << "\nYou have selected to guess the computers number" <<endl; do { cout << "\nBefore we begin please choose a difficulty." << endl; cout << "1 = Easy" << endl; cout << "2 = Medium" << endl; cout << "3 = Hard" << endl; cout << "Choice "; cin >> choice; cin.ignore(); switch (choice) // dificulty settings for guessing the computers number { case 1: cout << "My number is between 1 and 100" <<endl; theNumber = rand() % 100 + 1; break; case 2: cout << "My number is between 1 and 1000" <<endl; theNumber = rand() % 1000 + 1; break; case 3: cout << "My Number is between 1 and 10000" << endl; theNumber = rand() % 10000 + 1; break; default: cout << "Please pick a number" << endl; } do // Guessing the computers number { cout << "Enter a guess: "; cin >> guess; cin.ignore(); ++ tries; if (guess > theNumber) cout << "\nYour guess is too high!\n" << endl; if (guess < theNumber) cout << "\nYour guess is too low!\n" <<endl; } while (guess != theNumber); cout << "\n\n\tWell done you have guessed my number! " << endl; cout << "\n\tTries: " << tries; cout << "\n\nDo you want to try again? (y/n) "; cout << "\n\nNote! this will only replay the 2nd option" <<endl; //Play again option with a note. cout << "Hopefully this will be sorted in 1.6, please leave feedback" << endl; cin >> again; cin.ignore(); tries = 0; }while (again == 'y'); cout << "\nGuess again some other time!" << endl; } cin.get(); return 0; }

You might want to wrap the entire thing in a while (!Done), and set Done to true when you want to quit. Default it to false.

My suggestion would be to keep reading the book and keep practicing, lend/buy more books to advance in knowledge.
You will soon enough know how to do everything that you have in mind right now.
