Hi All.
I need to extract file's name from a full-path file's name string.
For instance:
char full_name[256] = {'\0'};
char name[256] = {'\0'};
sprintf(full_name, "C:\\folder\\file.ext");
And I need something like this:
ExtractFileName(full_name, name);
// now 'name' must has value "file.ext"
How to write such func ExtractFileName(const char *full, char *dest_name) ?
Sorry for my english. 5 2935

std::string has many member funcions which are well suited to this
task, for example rfind() and substr(). I suggest you familiarize
yourself with this class ASAP (and forget about using char* and all
the problems which come with that).
Also, there is the Boost tokenizer library at http://www.boost.org .

This is a C++ newsgroup, so
std::string full_name;
std::string name;
You'll need to #include <string>
sprintf(full_name, "C:\\folder\\file.ext");
full_name = "C:\\folder\\file.ext";
And I need something like this:
ExtractFileName(full_name, name); // now 'name' must has value "file.ext"

Make it
std::string ExtractFileName(const std::string& full)
{
// do the work of extracting just the file name from the whole path
// to do that, look up the find_last_of and substr member functions
of std::string
// return the file name string
}

Why don't you use std::string? You could try something like:
std::string ExtractFileName(const std::string& full)
{
std::string::size_type idx = full.find_last_of("\\");
if (idx == std::string::npos)
return full.substr(idx+1);
else
return ""; //do what you need to do to handle this case
}

Typo above. Should be:
if (idx != std::string::npos)
return full.substr(idx+1);
else
return ""; //do what you need to do to handle this case
