共用的幾個源代碼文件：shell

main.c 2.c 3.capp

代碼依次爲：ide

 1 #include<stdlib.h>
 2 #include "a.h"
 3 extern void function_two();
 4 extern void function_three();
 5 
 6 int main()
 7 {
 8     function_two();
 9     function_three();
10     exit (EXIT_SUCCESS);
11 }

View Code

#include "a.h"
#include "b.h"

void function_two(){}

View Code

#include "b.h"
#include "c.h"

void function_three(){}

還有三個文件：a.h b.h c.hz使用shell命令建立它們。函數

touch a.h b.h c.h
