c programming how to force stop the programme

To force stop a program in C, you can use the exit() function. Here are the steps to do it:

Step 1: Include the necessary header file

Include the <stdlib.h> header file at the beginning of your program. This header file contains the declaration of the exit() function.

Step 2: Call the exit() function

To force stop the program, call the exit() function and pass an integer value as the argument. This integer value represents the exit status of the program. Conventionally, a value of 0 is used to indicate successful termination, while any non-zero value indicates an error or abnormal termination.

Here's an example code snippet that demonstrates how to force stop a program using the exit() function:

#include <stdlib.h>

int main() {
    // Program code...

    // Force stop the program
    exit(0);
}

In the above example, the program will terminate immediately when the exit(0) statement is executed.

Please note that using exit() to force stop a program should be used sparingly and only in exceptional cases. It is generally recommended to allow the program to terminate naturally by reaching the end of the main() function.
