In this post, we will get to know how we can shut down our pc using c program, The header file stdlib.h is used to run an executable file shutdown.exe which is present in C:\WINDOWS\system32 the folder in Windows 7 and XP.
Below is the code to shut down your windows 7,8,10 pc
#include<stdio.h>
#include<stdlib.h> // contains system method
int main()
{
char ch; // declare a character
printf("Do you want to shutdown your pc now (y/n)?"); // show message
scanf("%c", &ch); // takes input
if(ch == 'y'|| ch == 'Y')
{ /*
/s is used to order the compiler
to shutdown the PC
*/
system("C:\\WINDOWS\\System32\\shutdown /s");
}
return 0;
}
we can use various things while executing shutdown.exe, for example, you can use /t option to specify the number of seconds after which the shutdown happens.
- Syntax:
"shutdown /s /t x";here x is the number of seconds after which shutdown will occur. - Example: By default, shutdown occurs after 30 seconds. To shut down immediately you can write
"shutdown /s /t 0"
If you wish to restart your computer then you can use "shutdown /r".
Below is the code to restart your windows 7,8,10 pc
#include<stdio.h>
#include<stdlib.h> // contains system method
int main()
{
char ch; // declare a character
printf("Do you want to shutdown your pc now (y/n)?"); // show message
scanf("%c", &ch); // takes input
if(ch == 'y'|| ch == 'Y')
{ /*
/s is used to order the compiler
to restart the PC
*/
system("C:\\WINDOWS\\System32\\shutdown /r");
}
return 0;
}
