    Text Game in C.

    So I want to learn C and continue going up to higher level programming languages. I thought the best way to do this would be to start game development because it's very difficult and you know you know the language when you have a fully functional game. I'm starting off just doing a text game. Just to get the basics and the jist of it all. My question is am I coding the options and cases correctly. I'm not going to post the in depth text but here is the way I did it. If it helps you can input your own variables into the 1,2,3 spots.
    Code:
    #include <stdio.h>
    
    
    void 1(){
         void 1(){
              }
         void 2(){
              }
         void 3(){
              }
             int input2;
             printf("Text");
             scanf("%d", &input2);
             switch(input2){
                           case 1:
                                11();
                                break;
                           case 2:
                                12();
                                break;
                           case 3:
                                13();
                                break;
                           }
             }
    void 2(){
         printf( "Text");
         }
    void 3(){
         printf( "Text");
         }
    int main(){
        int input1;
        printf( "Text");
        scanf( "%d", &input1);
        switch(input1){
                      case 1:
                           1();
                           break;
                      case 2:
                           2();
                           break;
                      case 3:
                           3();
                           break;
                      case 4:
                           printf( "Text");
                           break;
                      default:
                              printf( "Text");
                              1();
                              break;
                      }
                      scanf("%d");
                      getchar();
        }

    I don't get it. It's difficult to understand what you're getting at with this weird pseudocode. Why don't you post something that compiles?

    Start. Smaller.

    Can you write a "Hello World" program that compiles and runs?

    Well I'm already farther in than the "Hello World" program. I just wrote it in pseudocode because I'm a very paranoid person so I don't like to give any code. But seeing how it's hard to do it otherwise I guess I'll have to get over it. So here is the code.
    Code:
    #include <stdio.h>
    
    
    void play(){
         void assaultrifle(){
              }
         void sniperrifle(){
              }
         void submachinegun(){
              }
             int input2;
             printf("Select your weapon\n");
             printf("1. Assault Rifle\n");
             printf("2. Sniper Rifle\n");
             printf("3. Sub-Machine Gun\n");
             printf("Enter selection number\n");
             scanf("%d", &input2);
             switch(input2){
                           case 1:
                                assaultrifle();
                                break;
                           case 2:
                                sniperrifle();
                                break;
                           case 3:
                                submachinegun();
                                break;
                           }
             }
    void load(){
         printf( "Select which game save to load\n");
         }
    void multiplayer(){
         printf( "Select multiplayer game type\n");
         }
    int main(){
        int input1;
        printf( "1. Play Game\n");
        printf( "2. Load Game\n");
        printf( "3. Multiplayer\n");
        printf( "4. Exit\n");
        printf( "Enter selection number\n");
        scanf( "%d", &input1);
        switch(input1){
                      case 1:
                           play();
                           break;
                      case 2:
                           load();
                           break;
                      case 3:
                           multiplayer();
                           break;
                      case 4:
                           printf( "Goodbye\n");
                           break;
                      default:
                              printf( "Default selection...Play Game...\n");
                              play();
                              break;
                      }
                      scanf("%d");
                      getchar();
        }
    I'm just wondering if I'm getting at it correctly...I know it compiles and runs fine, I just want to know if there is a more efficient way.

    When I'm making a game, I have main() call a 1st menu, which is the most basic options, and a quit. That will (perhaps with other submenu's being called depending on the game), eventually reach a play1game() function. In play1game, there will be a large do while(game_Not_over && quit == 0) type loop. Everything to play one game will be handled inside that loop (which will typically call several other functions itself).

    main() really isn't used for much in a well designed game, except calling the first outer menu, and returning an int to the operating system, imo.

    I understand main() calling the 1st menu, but after that you lost me...could you give me an example in code? It would help out a lot more.

    ^ Something like this:
    Code:
    int main(void)
    {
        int status;
       switch(main_menu())
       {
           case 1: status = play1game();break;
           //etc
       }
       return status;
    }
    ......
    int play1game()
    {
         int quit_condition;
         int status;
         do
         {
          //game loop
         }while(!quit_condition);
         return status;
    }

    Where does main_menu come from in that?

    I think he means like this:
    Code:
    void PlayGame() {
        int keepPlaying = 1;
        while (keepPlaying) {
            DisplayWorld();
            GetInput();
            if (keepPlaying)
                UpdateWorld();
        }
    }
    
    void MainMenu() {
        // display menu
        // get option
        if (option == PLAY_THE_GAME)
            PlayGame();
        // etc.
    }
    
    int main(int argc, char *argv[]) {
        // handle command-line options
        // general setup
        MainMenu();
        // general teardown
        return 0;
    }

    In my example, it'd be a function that displays the choices, and returns the one selected by the user.
    (But that was for you to figure out. :P)

    So far this is what I've updated my game to, with the help of you guys.
    Code:
    #include <stdio.h>
    #include <stdlib.h>
    void Exit(){
         printf(" Now Closing\n ");
         }
    void Multiplayer() {
         printf(" Loading Multiplayer Option\n ");
         }
    void Load() {
         printf(" Load\n ");
         }
    void Play() {
         printf(" Play\n ");
         }
    void MainMenu() {
         int gameselectioninput;
         int playgame = 1;
         int loadgame = 2;
         int loadmultiplayeroption = 3;
         int exit = 4;
         printf("1. Play Game\n");
         printf("2. Load Game\n");
         printf("3. Load Multiplayer Option\n");
         printf("4. Exit\n");
         printf(" Enter Selection Number \n");
         scanf("%d", &gameselectioninput);
         if( gameselectioninput == playgame){
             Play();
             }
         else if ( gameselectioninput == loadgame){
              Load();
              }
         else if ( gameselectioninput == loadmultiplayeroption){
              Multiplayer();
              }
         else if ( gameselectioninput == exit){
              Exit();
              }
         }
    int main(int argc, char *argv[])
    {
        MainMenu();
        system("PAUSE");    
        return 0;
    }
    And manasij7479 I was just confused.
