C/C++ program to shutdown a system
How to shutdown your computer in Linux and/or Windows?
The idea is to use system() in C. This function is used to invoke operating system commands from C program.
Linux OS:
// C program to shutdown in Linux #include <stdio.h> #include <stdlib.h> int main() { // Running Linux OS command using system system ( "shutdown -P now" ); return 0; } |
Windows OS:
Shutdown/ Log off/ Restart a Windows OS
We will make use of system() from < stdlib.h > to perform a system operation with the help of a C program.To perform any of the afore-mentioned system operation we will code as:
#include <stdio.h> #include <stdlib.h> int main() { system ( "c:\\windows\\system32\\shutdown /i" ); return 0; } |
The argument to the system function is the path to OS and /i is one of the entity from the vast options available to us.To view the options, we run cmd and type:
C:\Users\User>shutdown
The shutdown command presents us with a list of options available for us.These are :
To perform different operations, we just replace the last “/path” in system() argument.The common operations are:
Shutdown
system("c:\\windows\\system32\\shutdown /s");
Restart
system("c:\\windows\\system32\\shutdown /r");
Logoff
system("c:\\windows\\system32\\shutdown /l");
