Yes, you can.

Inside your c program just call the "system(your_commnad)" .
Remember you have to run this program as supper user.

For example.

#include <stdio.h>
#include <stdlib.h>

int  main()
{
      printf("Going to shutdown the system....\n");

       /* 
           It will execute the "shutdown" command from the c program.
           You can provide "poweroff" in the place of "shutdown".
           To know more about system(), do a <man 3 system>.
      */
      system("shutdown -P now");  // see man shutdown for more options.
}

Given an array of integers (possibly some of the elements negative), write a C program to find out the *maximum product* possible by adding 'n' consecutive integers in the array, n <= ARRAY_SIZE.

Also give where in the array this sequence of n integers starts.
