Black Horse programmer--"Dark Horse video note" C Language basic notes and common mistakes

In summary, there are three types of annotations:

1. Single-line Comment

   1:  //haha single-line comment

2. Multi-line annotations

   1:  /*

   2:  asdfasdfasdfasdfasdf

   3:  * /

Where multiple lines of comments are written

   1:  /*

   2:    *  function is ...

   3:    * /

   4:  void dosomething () {...}

The compiler can automatically recognize when the mouse clicks on the function name thing. The right side of the system can display the corresponding comment:

   1:  #include <stdio.h>

   2:  //This is a main function,//is the entry of the whole program 4353454//355345435

   3:  int main ()

   4:  {

   5:  /    * This function can output "111" to the screen 5435435345

   6:      printf ("111\n"); 534543543543*/

   7:      printf ("333\n");

   8:      printf ("444\n");

   9:      printf ("555\n");

  Ten:      return 0;
