# Polymorphism
## Inclusion
## Coersion
## Parametric
### Examples
* **C++ Template (Static)**
The types are taken as variables and then instantiated with particular type as needed while compiling.
```cpp
template
T Add(T a, T b)
{
return a + b;
}
int main()
{
return Add(1, 2);
}
```
## Ad-hoc
### Examples:
* **C++ Operator Overload (Dynamic)**
The same operator shows different behaviours for different types.
```cpp
"A" + "B" // "AB" : String Concatenation
1 + 2 // 3 : Integer Addition
```
* **C++ Function Overload (Dynamic)**
Dynamically choose which function to use while running.
```cpp
int get(int a) { return a; }
int get(int a, int b) { return a + b; }
int get(int a, int b, int c) { return a + b + c; }
...
```
## Sub-Type
### Examples:
* C++ Virtual Table
