C++ Programming - OOPS Concepts - Discussion

What is transient and pseudo polymorphism ? and it is a type polymorphism ? then explain more about Ad-hoc polymorphism ?

What is mean by transient and pseudo polymorphism ?

Can anyone explain more about Ad-hoc polymorphism, transient and psuedo polymorphism ?

Ad-hoc polymorphism allows functions with the same name act differently for each type. For example, given two ints and the + operator, it adds them together. Given two std::strings it concatenates them together. This is called overloading.

Here is a concrete example that implements function add for ints and strings,

#include <iostream>
#include <string>

int add(int a, int b) {
return a + b;
}

std::string add(const char *a, const char *b) {
std::string result(a);
result += b;
return result;
}

int main() {
std::cout << add(5, 9) << std::endl;
std::cout << add("hello ", "world") << std::endl;
}
Ad-hoc polymorphism also appears in C++ if you specialize templates. Returning to the previous example about max function, here is how you'd write a max for two char *,

template <>
const char *max(const char *a, const char *b) {
return strcmp(a, b) > 0 ? a : b;
}
