Question # 1

What is data structure? And why we need data strcuture.

Ans 1: Data structure is a container to store collection of data items in a specific layout. High level programming languages provide data structures in order to store and organize data. Different data structures are available in C programming langauge. Array is the one onf the most common data structure in C language.
Ans 2: Need: We need data strcutre to store and process large amount of data.
Example: The marks of 100 students we does not need to declare 100 variables we should use array.

Question # 2

How can we access an array elements.

Ans 1: Each element of the array has an inded that fan be used with the array name. The element fo the array an be accessed by using its index.

Question # 3

Why we use loop in programming.

Ans 1: We often face problems whose solution may require executing a set of statements repeatedly. In such situations, we need a structure that would allow repeating a set of statements.

Question # 4

What is Iteration.

Ans 1: Each run of a loop is called iteration In a computer program, a common form of iteration is aloop. Loop stucture is used to repeat a number of statements up to a specified number of times or until a special condition fulfiled.

Question # 5

What is the most important property of an array.

Ans 1: An important property of array is that it stores all the values at consecutive locations inside the computer memory.
Ans 2: It can hold multiple values of same data type.

Question # 6

What happen if condition never becomes false at any point in for loop.

Ans 1: Always make sure that he conditions become false at some pooint, otherwise the loop repeats infinitely and nevewr iteration.

Question # 7

Define Array

Ans 1: An array is a data structure that cfan hold multiple values of same data type e.g. an in to array can hold multiple integer alus, a float array can hold multiple real vales and so on. An important property of array is that it stores all the values at consecutive locations, inside the computer memory.

Question # 8

What happens if we try to initialize an arrray in a single statement after declaring it.

Ans 1: The compiler generates an error if we try to initialize the whole array in one separate statements after declaring it. The compiler will give the following error message.
" Initializing whole array after declaration not allowed"

Question # 9

Waht happen if we do not initialize an array at the time of declaration.

Ans 1: If we do not initialize an array at the time of declaratio, then we need to initialize the array elements one by onee it means that we cannot initialize all the elemets of arry in a single statement.

Question # 10

Data Structure.

Ans 1: Data structure
Ans 2: Data structrue is a container to store collection of data items is a specific layout. High level programming language provide data strcture s in order to store and organize data. Different data structures are available in C programing . Array is the one of the most common data structure in C language.
