Question

In the context of programming, what occurs when multiple functions exist in the same scope but have different signatures?

a) Overloading
b) Overriding
c) Polymorphism
d) Inheritance

Answer 1

When multiple functions exist in the same scope but have different signatures, it is known as overloading. Overloading allows multiple functions with the same name to perform different actions based on the number and types of parameters passed.

Step-by-step explanation:

When multiple functions exist in the same scope but have different signatures, it is known as overloading. Overloading allows multiple functions with the same name to perform different actions based on the number and types of parameters passed.

1. For example, consider a function called 'add' that takes two integers as parameters and returns their sum. If you also create another function called 'add' that takes three integers as parameters and returns their sum, this is an example of function overloading.
2. When the program calls the 'add' function, the appropriate version of the function will be selected based on the number and types of arguments passed.
