1) Compiler will throw the error as C++ doesnt support +
operator for string. Another point is T c = Add
("SAM","SUNG"), where the function call assign to a
TEMPLATE object type, it syntactical error.
2)We need to write a seperate add function as given below
char* Add( const char *s1, const char*s2);
This will solve the problem
