A. Halt execution of program

To halt the execution of a program in various programming languages, different approaches are used. Below are some examples for commonly used programming languages:

1. Python:

– One common method to halt execution in Python is by using the `sys.exit()` function. You need to import the `sys` module before using it.

import sys

sys.exit()

2. Java:

– In Java, you can use `System.exit(int status)` to halt the execution of a program. The status `0` indicates successful termination.

“`java

System.exit(0);

3. C:

– In C programming, you can use the `exit()` function to stop program execution. You need to include the `stdlib.h` header file to use this function.

“`c

#include

int main() {

// …code

exit(0);

}

4. C++:

– Similar to C, you can use `exit(0);` in C++. Ensure to include the `cstdlib` or `stdlib.h` header.

“`cpp

#include

int main() {

// …code

exit(0);

}

5. JavaScript (Node.js):

– In Node.js, you can use `process.exit();` to halt the
