Question

Define functions with example.

Answer 1

Answer:

A function is a block of code that performs a specific task. C allows you to define functions according to your need. These functions are known as user-defined functions.

For example: Suppose, you need to create a circle and color it depending upon the radius and color.

Answer 2

Function:

• A function is a block of prearranged, reusable code that is applied to perform a single, interrelated action.  

• Functions provide improved modularity for one’s application and a great degree of code reusing.

Example:

Functions like printf() and main() are named built-in functions delivered by the language itself, but one can write his/her own functions as well.
