In the context of the C++ programming language, explain function overloading and overriding. Distinguish between them.

Modifying the signature, i. e. the function can be defined in more than one way depending on the number of parameters, the data type of the parameters, and the return type.

Adding a function from a base class to a derived class that has the same return type and parameters is called function overriding. Only derived classes allow for this.

Major differences to be noted between these two:

When one class inherits from another, functionalities are overridden. In the same class, overloading can occur.
There must be a unique function signature for each overloaded function. This means that each one must have a different number or type of parameters. When overriding, function signatures must be the same.
Different from overridden functions, which are in a different scope, overloaded functions are in the same scope as them.

The examples demonstrate both of these concepts well.

Â Â Â Â cout << “Inside Overloaded Method 1” << endl;

Â Â Â Â cout << “Inside Overloaded Method 2” << endl;

void overloadedMethod(int x1, float x2)

Â Â Â Â cout << “Inside Overloaded Method 3” << endl;

Â Â Â Â int x = 5;

Â Â Â Â float y = 5.5;

Â Â Â Â overloadedMethod(x);

Â Â Â Â overloadedMethod(y);

Â Â Â Â overloadedMethod(x, y);Â

Â Â Â Â return 0;

Inside Overloaded Method 1

Inside Overloaded Method 2

Inside Overloaded Method 3

public:Â

Â Â Â Â Â Â virtual void print(){ cout << “Testing Function”; }

class Sample: public Test

public:Â

Â Â Â Â Â Â Â void print(){ cout << “Inside a Sample Function”;}

Â Â Â Â Test obj = new Sample();

Â Â Â Â obj.print();

Â Â Â Â return 0;
