Answer Posted / mms zubeir
There are two things to be considered here.
First, T will be an unknown type in the place where we call
which gives a compilation error.
Second, if we call like this:
std::string c = Add("SAM", "SUNG"); or,
char* c = Add("SAM", "SUNG");
the compiler will convey an error since the arguments to
Add are interpretted as char pointers. The error may be
something like, "cannot add two pointers....".
