C++ : Template specializations

Assuming you have a piece of code that is templatized and looks like this

template
void prettyPrint(T value, char* buf);

now assume that you are using sprintf for formatting the input .

that being the case you can use template specializations like this :

template<> void prettyPrint(int value, char* buf){
sprintf(buf, "%d", value);
}

template<> void prettyPrint(char value, char* buf){
sprintf(buf, "%c", value);
}
