🧠 Real-Life Example:

Real World	Polymorphism Concept
Tumhara mobile ka volume button:

Call mein: call volume
Music mein: music volume

| Same button (same name), different kaam |

🔑 Types of Polymorphism in C++:

Type	Also Called As	When It Happens
✅ Compile-time Polymorphism	Static Binding	During compilation
✅ Run-time Polymorphism	Dynamic Binding	During execution

🟦 1. Compile-time Polymorphism

➡️ Achieved by:

🔹 Function Overloading
🔹 Operator Overloading

🔷 A. Function Overloading

Same function name, different parameters

cpp
CopyEdit
#include<iostream>
using namespace std;

class Print {
  public:
    void show(int a) {
        cout << "Int: " << a << endl;
    }

    void show(string s) {
        cout << "String: " << s << endl;
    }
};

int main() {
    Print p;
    p.show(5);        // Int: 5
    p.show("Nikhil"); // String: Nikhil
}
