C++ : template specialization

template <>
char* Add<char*>(char* a , char* b){
return strcat(a,b);
}

char * res = Add<char*>("foo","bar");

This code refers to a new type of syntax for templates called template specialization syntax.
Generally when you write code for templates .

you end up using stuff like

template<class>

but say you want the same generic code for many cases . In the above mentioned code for example if the add function used the "+" operator to add two types it would have not worked for char* pointers , because the "+" operator does not work with them .

by using the syntax as mentioned above its possible to tell the compiler that there are exceptions to your generic code and that for special cases these new methods should be called.
