exit program

what is another alternative to

Code:

---

system("pause");

---

using a standard c library function

I need to get this to work =(

Code:

---

printf ("Press enter to close window...");
        scanf (" %c", &close);
        if(close == '\n')
                EXIT_SUCCESS;
        EXIT_FAILURE;
        exit(EXIT_SUCCESS);

---

The safest thing to do, if you MUST use scanf(), is to immediately remove the left over newline char, from the input buffer:

Code:

---

scanf("%s", string)
getchar(); //removes the newline char, will NOT halt and wait for input
scanf("%c", &myChar) //now myChar has clean input steam.
(void) getchar(); //another way, if the plain getchar() gives you warnings

/* to remove several char's from the input stream */
while((ch=getchar()) != '\n');

system("pause"); // is a poor habit to get into.

---

I'm not really understanding it

Code:

---

        getchar();                                                    //clears previous newline char
        printf ("Press enter to close window...");
        scanf ("%c", &close);

        //while ( getchar() != '\n' );

---

should i be doing the EXIT_SUCCESS afterwards?

I got mines to work, this is what i did.

Code:

---


while ( getchar() != '\n' );

printf ("Press enter to close window...");
scanf ("%c", &close);
if(close == '\n')
return 0;

Thanks for the help. =)

exit(1) to exit from....
getch() works exactly like system("pause")

getch() is not a standard C function -- read the original post.

Huh......... Can't you use console library then??

You can use getchar(). or run your program from shell/cmd.
getch()/conio.h is non-standard library/function. You should avoid using it unless you really need it.

I use this all the time, to hold open the console window in Turbo C:

Code:

---

at the end of main:
  printf("\n\n\t\t\t    press enter when ready"); //to center it, use three tabs and four spaces before "press"
  (void) getchar(); //the void part eliminates a warning
  return 0;
} //end of main


/* rarely, when the input stream might get really dirty, I'll use this */

  printf("\n\n\n\t\t\t    press enter when ready");
  while((ch= getchar)) != '\n');
  (void) getchar(); //the void part eliminates a warning
  return 0;
} //end of main

When you get a chance though, try out Pelles C -- woooo! It's nice!
