C++程序中获取不带文件路径和后缀的文件名

string getName(const char* full_name)

{

string file_name = full_name;

const char* mn_first = full_name;

const char* mn_last = full_name + strlen( full_name );

if ( strrchr( full_name, '\\' ) != NULL )

mn_first = strrchr( full_name, '\\' ) + 1;

else if ( strrchr( full_name, '/' ) != NULL )

mn_first = strrchr( full_name, '/' ) + 1;

if ( strrchr( full_name, '.' ) != NULL )

mn_last = strrchr( full_name, '.' );

if ( mn_last < mn_first )

mn_last = full_name + strlen( full_name );

file_name.assign( mn_first, mn_last );

return file_name;

}
