Is use of the std::snprintf(. . .) std::string method preferred over the plain C++ snprintf(. . .) function? If so what are the risks?

snprintf is a C function. It is included in <stdio.h>.

If you are using your C++ compiler you would include <cstdio> which just includes <stdio.h>.

The only way I can answer this question is to say the printf family of functions can only work with built-in types. None of your user defined types can use these functions. So by using printf functions you built limits to your code and make it non-reusable and non-extensible.

Let me also add that if there are snprintf function calls buried throughout the code, each of these carries a part if the UI. There is no one place where the UI is controlled. By changing, or removing, one of these calls you have a cascading effect and can't see the complete effect of the change at the program level. In past decades this was called "spaghetti code".

Maye you could say more about your concerns.
