    menu help

    I've had a search of the forums and i foudn some code for a menu. I've basically got my game up and running and thought a menu system might be good.

    this code works apart from it exit's what ever you type.

    I'm also quite stuck on how to get the first option to just continue with the game. I've tried adding initalise to it but that does not seem to do it

    Any one got any ideas?
    Code:
    {
      int selection;
      printf("1. Start Game\n2. Exit\n");
      printf("\nPlease Choose an option: \n");
      scanf("%d", &selection);
      
      switch(selection){
        case 1:
          intialise();
          break;
        case 2:
          exit(1);
          
        default:
          printf("Invalid selection\n");
          break;
      }
      return 0;
    }
        
        intialise();
    
    /* Rest of my code is here*/

    It's too incomplete to comment
    For starters, the menu code should be in some kind of loop, otherwise you just get to ask the question once, and then the program exits anyway.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Thats all i need. I only need it to ask it at the begging of the program.

    Welcome

    Press S or 1 to start
    Press E or 2 to exit.

    Thats it.

    It's just a simple if user selects 1 then continue if user selects 2 exit menu.

    hope this helps..

    Code:
    /*function prototypes */
    void menu(void);
    void game(void);
    
    int main(void)
    {
        menu();  
    
        return 0;
    }
    
    void menu(void) {
        int selection;
    
        printf("1. Start Game\n");
        printf("2. Exit            \n");
        printf("\nPlease Choose an option: \n");
        scanf("%d", &selection);
      
        switch (selection) {
            case 1:  game();
                     break;
            case 2:  exit(0);           /* exit game */    
          
            default: printf("Invalid selection\n");
                     menu();          /* simple recursion, can be accomplished with while(); */
         }
    }
    
    void game(void)
    {
        /* insert game-code here */
    }
