Programming Road (1), writing program Open Notepad, calculator, etc.

First, the command line startup program

To close a program from the command line:taskkill/f/im program name. exe

Second, open Notepad, calculator

 
1 #include <stdlib.h>
2 
3 void main(){
4 system("notepad");//Open Notepad
5 system("pause");
6
7 system("calc");//Open the calculator
8 system("pause");
9 }

Third, parallel open program

1 #include<stdlib.h>
  2 
  3 void run1(){
  4 system("notepad");
  5 system("calc");
  6 system("mspaint");
  7 }
  8 
  9 void run2(){
10 system("start notepad");
11 system("start calc");
12 system("start mspaint");
13 }
14
15 void main(){
16 run1();//In turn
17 run2 (); / / added start is parallel
18 } 

Four, Notepad programming (disguised as a master, ^_^)

1, first write a program with Notepad

2. Run vs Developer Command prompt

3. Switch the drive letter to the code file path, compile the link with "CL", Generate "1.obj" and "1.exe" files

Five, switch machine spoof, open file, open directory, etc.

1 #include<stdlib.h>
2 void main(){
3 system("Shutdown -s -t 60");//Shutdown after 60 seconds
4 system("pause");
5 system("Shutdown -a");//Cancel the shutdown
6 } 

1 #include<stdlib.h>
  2 void main1(){
  3 system ("explorer.exe F: \\ Baidu cloud download \ "MATLAB image processing examples detailed"); / / file manager Open any directory, pay attention to the double slash
  4 system("pause");
  5 }
  6 //Open the complex directory \\->\ \"->"
  7 void main2(){
  8 system("\"C:\\Program Files\\Internet Explorer\\iexplore.exe\"");//Open the IE browser
  9 system("pause");
10 }
11 //Open the file (can be a document, video, picture)
12 void main3(){
13 system("E:\\1.jpg");
14 }
15
16 void main4(){
17 system("D:\\360\\360se6\\Application\\360se.exe www.qq.com");//360 browser opens the specified website
18 }
19
20 void main(){
21 system("start calc");
22 system("pause");
23 system("taskkill /f /im calc.exe");
twenty four }
