C program to shutdown and restart your computer

How to shutdown your computer by c program

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
int main()
{
               char st;
          clrscr();
          printf(” Are you sure to shutdown your computer. Please mention(y/n)”);
          scanf(“%c”,&st);

          if(st==’y’ || st==’Y’)
              {
           system(“c:\windows\system32\shutdown /s”);
           system(“pause”);
          }
 return(0);
}

Logic of the above program is so simple. First we have included standard library file and defined one variable having character type. The system command will open the particular path to shutdown your computer.

How to restart your computer  by c program.

Here is the code of it.

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
int main()
{
                    char st;
             clrscr();
             printf(“Are you sure to restart your computer?.Please mention it(y/n):”);
             scanf(“%c”,&st);

             if(ch==’y’ || ch==’Y’)
            {
                 system(“c:\windows\system32\shutdown /r”);
                 system(“pause”);
             }
           return(0);
}

Logic of above program is same as we mentioned for first program. Firstly it include library file and then open the path of restart command to perform desired operation in c program.

Important note
It will be little tricky in turbo c compiler. If you are using turbo c then you just need to compile your program with help of ALT+F9. You doesn’t need to run it directly from inside the turbo c. You have to go in particular drive and open exe file of the program. That’s it!

So it is a good practice to execute this type of programs. Tell me about your experience of this program in comment box. If you need any help then don’t be shy.Just ask me!
