Explanation / Answer

Answer to Question 1; Array

Each variable is a seperate item which must be declared and processed individually, Whereas , an array can hold a group of values having same data type.

Answer to Question 2 :Size declarato

Number of values an array holds depends on the size of the array.

For ex: If a[5] is an array , 5 is the size of values which the array can hold,

the above array can hold values from a[0],a[1],....a[4]. The number 0,1,..4 indicate the index of the array element

Answer to Question 3 :Subscript

In array a[5], each individual element can be accessed as a[0],a[1],a[2],...a[4]. Where the numbers 0,1,...4 are called array subscripts.

Answer to Question 4: Bubble

Bubble sort is the simplest method of searching na item in an array.

The algorithm starts at the beginning of the data set. It compares the first two elements, and if the first is greater than the second, it swaps them,It continues doing this for each pair of adjacent elements to the end of the data set. It then starts again with the first two elements, repeating until no swaps have occurred on the last pass.

Answer to Question 5: The array itself.

Answer to Question 6: Parallel arrays

This term describes two or more arrays that hold related data, and the related elements in each array are accessed with a common subscript.

Answer to Question 7: Two subscripts .

For ex a[5][10] is a two dimensional array, element from first row first column can be accessed as a[0][0].

Answer to Question 8: Rows and columns

Answer to Question 9:None of the above.

A 3-D array is considered as an array of 2-D arrays.

Answer to Question 10:Integer

Answer to Question 11:Subscript or index.

Answer to Question 12:This is an array declaration and initialization.

Answer to Question 13:One

In Declare Integer score [5] = 83, 92, 78, 94, 71, the subscript for element 92 is One

Answer to Question 14:Search Value

Answer to Question 15:When working with arrays most programming languages perform _Array bound Checking_, which means they do not allow programs to use invalid subscripts.

Answer to question 16:Off-by-one error

Answer to Question 17: True.

Each array elements can be specified using array index or subscript

Answer to Question 18:False

Arrays can also be declared and initialzed in the same statement

Answer to Question 19: True

Array bound checking typically happens while a program is running.

Answer to Question 20:False

Answer to Question 21: True

Answer to Question 22:True

Since its a two dimensional array, each element can be accessed using two subscipts, where first subscript indicates and second subscript indicates column.

Answer to Question 23:True

It is possible to create arrays with multiple dimensions, to model data that occur in multiple sets.

Answer to Question 24:False

In mullti dimension arrays, each elements needs to be of same data type.

Answer to Question 25:False

An array is a way to hold more than one value at a time
