Introduction of Variable in C Language

Variable in any programming language when we start programming then first thing which we start with is variable. This chapter will give full knowledge of variable’s operation .So let’s start learning process with constant.

Constant

A constant is a value that newer get change. Like value of g (gravitational force) is 9.8, value of PI is 3.14 or your date of birth. Examples of different type of constant are follows

Integer

Integer is numbers that exclude decimal part. For Example if I ask to you that how many siblings you have. Your reply will always be in integer without decimal part.

C Language Data Type

A block diagram can represent a system working model .Here I am going to show you block diagram of computer which is also  follows by many types of machines.

Features of C Language

Modular

C language is also known as building block of function because everything you have do in C with the help of functions. That is why C language uses modular approach to solve huge problem through small modular approach. Modules make our work easy to solve any type of programming problem in a simple way. example of modules are function. A function is a collection of statements which design for some specific task.

Recursion

When a function called by itself known as recursion. Recursion helps to solve a complicated task in a few line of code which decrease compile time and increases software performance.
