What is the better way for convert a numeric type into a const char *?
It is a good idea?
Using a const char * is prone to Undefined Behaviors. If there's a way to use std::string instead, then try to do that.
But - if you must use a const char * [say for a 3rd party interface that requires it] then that's as good as any method.
Be aware of the potential for an exception, and be ready to deal with it.
