If you want to understand file’s type based on its contents, you can check the file’s binary signature.
If you want just to check the extension, you have 2 nice options:
Use std::string functions
find,find_first_of,find_last_ofandsubstrto write your own logic that analyzes the file name.Use boost filesystem library‘s function
extension.
