## What is C function?

A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions. … A function definition provides the actual body of the function.

So the difference between the function and function call is, A function is procedure to achieve a particular result while function call is using this function to achive that task.

## What are the two main types of functions in Python?

There are two basic types of functions: built-in functions and user defined functions. The built-in functions are part of the Python language; for instance dir() , len() , or abs() . The user defined functions are functions created with the def keyword.

Breaking the code in smaller Functions keeps the program organized, easy to understand and makes it reusable. … It reduces the complexity of a program and gives it a modular structure.

## What is the example of function and relation?

In mathematics, a function can be defined as rule that relates every element in one set, called the domain, to exactly one element in another set, called the range. For example, y = x + 3 and y = x2 – 1 are functions because every x-value produces a different y-value. A relation is any set of ordered-pair numbers.
