Get string Middle by C

Key:

int int int'n '; i++ ) {;}}     

For example:

1#include <stdio.h>2#include <stdlib.h>3#include <string.h>4 5 #defineStr_len 106 7 voidStr_get_middlle (Char*result,Char*STR,intStartintend);8 9 intMainintargcChar*argv[])Ten { OneFILE *FP =NULL; A     Char*file_path =NULL; -     CharStr[str_len] ="", result[str_len] =""; -  the     if(ARGC = =1){ -printf"Too few augument (s) \ n" ); - exit (exit_failure); -     } +  -File_path = * (+ +argv); +  A     if(fp = fopen (File_path,"R")) ==NULL) { atprintf"Opening file error! path:%s\n", File_path); - exit (exit_failure); -     } -     Else{ -printf"Opening file [%s] was successfully!\n", File_path); -     } in  -  to      while(Fgets (str,sizeof(str), FP)! =NULL) { + //printf ("%s", str);  -Str_get_middlle (result, str,0,1); theprintf"%s-", result); *  $Str_get_middlle (result, str,2,3);Panax Notoginsengprintf"%s-", result); -  theStr_get_middlle (result, str,4,5); +printf"%s\n", result); A     }  the      +     return 0; -}

Means: 00112233 >> 00-11-22-33. This code can formt MAC address.
