A.1. Exercises

In all the following problems, the reader should assume that a single writable file with some template code is given; more files can be added, and the rest of the project is read-only.

A.1.1. Extension

A function template is given:

template <typename T>void f(T x){   printf("hello T");}

• Add another overload that is to be called for every class that derives from BASE and prints “hello BASE-or-derived”
