Jumping to the End of a Program

Question:
I have a function halfway through a program, which should allow the user to quit the program, at the moment it just carries on to the next function call. How do I quit the program?

Answer:
Make sure that your termination function calls exit(), which is defined in . Calling exit() will terminate your program.

For example:

#include 

void term_func(int n)
{
  exit(n);
}

int main()
{
  int option;
  // get user's choice from stdin
  if (option == QUIT)
  {
   term_func(0); //call termination func
  }
  // continue  
}
