Generic programming means that you are not writing source code that is compiled as-is but that you write "templates" of source codes that the compiler in the process of compilation transforms into source codes. The simplest example for generic programming are container classes like arrays, lists or maps that contain a collection of other objects. But there's much more to generic programming. In the context of C++ (and called meta programming) it means to write programs that are evaluated atcompile time.
