## C Language: sqrt function (Square Root) - TechOnTheNet.

In mathematics, a function is a relation between sets that associates to every element of a first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers. Functions were originally the idealization of how a varying quantity depends on another quantity. For example, the position of a planet is a function of time.

C Functions In this tutorial, you will be introduced to functions (both user-defined and standard library functions) in C programming. Also, you will learn why functions are used in programming. A function is a block of code that performs a specific task. Suppose, you need to create a program to create a circle and color it. You can create two functions to solve this problem: create a circle.

C User-defined functions In this tutorial, you will learn to create user-defined functions in C programming with the help of an example. 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.
