CodePudding user response:

In the following way to print, can know the reason for the error

 if (! (f_file=fopen (file_name, "rb"))) 
{
Printf (" always open the file % s!" , file_name); 
Printf (" % s \ n ", the strerror (errno) : 
return; 
}

Note, every open file Suggestions with it, and need to introduce string. H and errno. H header file

Image or not, I just download from the Internet, access problem?
