Dear Manoj Kumar Singh,
To be sure the students create a function you must use it. To get it you may do the following:
Request the students to write the add function, but not the main function, in the add.c file (use requested files to ensure the file name).
write a program "useAdd.c" in the "execution files" with the code:
#include "add.c"
int main(){
    add();
    return 0;
}
Best regards,
Juan Carlos.
