typedef foo bar

means that bar is now an alias for type foo

now I have this:

typedef match_results<const char* cmatch>

I am not sure what this more complex code means . Please can someone explain what that code means (in detail as I am a beginner)?

Many thanks

typedef foo bar

typedef match_results<const char* cmatch>

I'm not sure if both have a valid C++ syntax:
