Homework & Coursework Questions

Hello all, I am writing a program where user enters an integer and the program creates that number of processes. Each child process generates a random integer. When a child process calls a procedure say Myprocedure it should terminate where as the parent process wait for the child to terminate.

Is this homework?

What have you tried?

yeah sort of a HW, but more of a prac program. so far I have tried this - should the fork() be in a separate loop, like first create all processes and then print random integer and at last terminate.
int Myproc(int id) // couldn't figure out this part.

Code:

{
  if(!id)
  return wait(id);

  else
  exit(1);
}

int main()
{
	pid_t p_id;
        int num;
        printf("Enter Number of processes : ");
        scanf ("%d",num);
for (int i = 0; i < num - 1; i++)
	
{
        p_id = fork();

	if(p_id == -1){
		printf("Unable to create process/child");
		return(-1);}

	if(!p_id)
		//printf("Parent Control Starts here.");
	else
	// Child Control
        // Generate random number.
        printf (" Child ID = %d --- %d", p_id, (rand() % 100 + 1) ); // random integer between 1 to 100
}// end for

}//end main
