Computer programming is all about processing information.This information can be of any format like Image, Audio, Video, Text etc.When it comes to computer programming, the data of different formats is represented in binary form ( in 0's and 1's), i.e. in groups of Bits known as Bytes.For easier and efficient processing, data is classified into different types (data types) such as char, int, float, double, array, enum etc. These data types can be grouped as primitive and derived. (We shall learn more about data types in the later sections.)As their names suggest, primitives form the primary building blocks (they usually have built-in support in the programming languages) and derived data types are usually made up of one or more primitive types.The memory occupied by a variable depends on its data type.Click on Live Demo to know about different data types available in C.Each data type determines:the meaning of the data that it representsthe possible values that it can takethe way or format in which the values of this type are storedthe possible operations that can be performed on itIn C, we need to declare the type of a variable before using it.For example, if we want to store a value 75 in a variable with name marks,we cannot directly writemarks = 75;We first have to declare the variable marks to be of int type, as given below:int marks;and then we can assign the values as follows:marks = 75;int marks;marks = 75;We can also declare and initialize the variable in a single step, as:int marks = 75; We shall learn more about various data types in the ensuing exercises.Select all the correct statements from the given statements.The contents of PDF and text files are not stored as bits in a hard disk.Type of data (data type) determines how much memory will be allocated to the variable.In C, when the user wants to use a new variable, variable's data type must be declared before using it.If a text file contains only a decimal value 12, then the value 12 is stored as 1100 in its binary form
