How can I use "goto" for group of multiple statements?

How can I use "goto" for group of multiple statements in the code as following:

Code:

---

title:
{
printf("______________\n")
printf("The Hollywood\n");
printf("______________\n")
}

printf(.....)
scanf(.....)                  ///other statements (main program)
clrscr();

goto title;

---

In this code, I want to print the title at first and then use all function (between) in a program. At last I want to clear everything and reprint the title.

Just imagine, as a starting point for discussion, that - other than what you post - we have no idea what you are trying to achieve.

Now, try reading your post with that in mind. Do you think it actually gives us any useful idea of what you are trying to do?

If you think it does, you're wrong.

ANY backwards goto is a sign that you really ought to be using a loop construct of some kind.

That sounds more like a function than a goto. If you just want to print the title more than once then write a function called PrintTitle(). Or something similar.

If you want to go back to the beginning of the program and repeat all the logic then look into what Salem suggested and decide if you want a loop that runs a fixed number of times (for loop) or a while loop that runs conditionally.

I agree with grumpy though in the fact that your question is very broad and non-descript leaving it up to us to try and interpret both the question and the solution.

Don't.

You should think of a label as being bound to one statement rather than a group of statements. Try the following:

Code:

---

int main(void)
{
    char buf[100] = "";
title:
    printf("______________\n");
    printf("The Hollywood\n");
    printf("______________\n");
   
    printf("Press q to quit: ");
    scanf("%99s", buf);
    if (buf[0]=='q')
        goto end;
    printf("You pressed %s\n", buf);
    printf("\n\n\n");   
    goto title;
end:
    printf("Bye.\n");
    return 0;
}

As others mentioned, this would be much better expressed as a while loop.

Have to echo that this is the wrong approach (the warning sign is goto which, while it has its uses, should be a big red cross in your head whenever you find yourself using it).

What you probably want is a function, called title, that executes those bits of code. Then you call that function, just like you called clrscr(), in the places in the program that you need it. Then, if you want, you can loop around so you do it more than once.

Read up on C functions and loops, and forget about using goto. I'm not a goto-hater (which some are since Dijkstra shouted his mouth off), but this is not a good use for goto when there are better ways of doing EXACTLY what you want using the proper functionality of C. Seriously. It makes me cringe. Stop it. And whoever you learned that from, give them a poke in the eye from me.

Yes. One technique is just to write the code using your functions before you've actually written them. This is called top-down design.

Code:

---

while (true) {
    showTitle();
    showPrompt();
    char cmd = getCmd();
    if (cmd == 'f') {
        foo();
    }else if(cmd == 'b') {
        bar();
    }else if(cmd == 'q') {
        break;
    }else{
        showErrorMessage();
        pause();
    }
}

---

Then you can fill in the actual definitions afterwards for foo(), bar() etc. afterwards.

back in BASIC days, Batch files, etc...GOTO and GOSUB was powerful, and one of the only options. Although GOTO is in the C, and useable, it is frowned upon because there are more stable options to use. Sych as functions, switches, loops, etc....

you could use it, but i would recommend finding a more practical option.
