One 、 Design thinking

Shutdown Sequence
Just run , The computer will shut down in a minute , If input ： I am a pig , Will cancel the shutdown .

Two 、 Programming

1. Include header file

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

2. operation

//shutdowm -> Shutdown widget
//-s -> Set shutdown
//-t -> Set the time to shut down
//-a -> Set to cancel shutdown

3. The main function

int main()
{
    
	char input[20] = {
     0 };
	system("shutdown -s -t 60");

again:
	printf(" Please note that , Your computer is 1 Shut down in minutes , If input ： I am a pig , Will cancel the shutdown \n");
	scanf("%s", input);
	if (strcmp(input," I am a pig ") == 0)// Two string comparisons cannot use the equal sign 
	{
    
		system("shutdown -a");
	}
	else
	{
    
		goto again;
	}

	return 0;
}
