Question 1

It is used to “jump out” of a switch statement.

Answer 1

Break Statement

Question 2

It can also be used to jump out of a loop.

Answer 2

Break Statement

Question 3

This statement breaks one iteration
(in the loop), if a specified condition occurs,
and continues with the
next iteration in the loop.

Answer 3

Continue Statement

Question 4

It allows us to
execute specific blocks of code a number of
times.

Answer 4

Repetition Control Structures

Question 5

is a statement or block of
statements that is repeated as long as some condition is satisfied.

Answer 5

While loop

Question 6

the statement inside this loop is executed several times as long as the condition is satisfied.

Answer 6

Do while loop

Question 7

It allows execution of the same code a number of times.

Answer 7

for loop

Question 8

It Initializes the loop variable.

Answer 8

Initialization Expression

Question 9

It compares the loop variable to some limit value

Answer 9

Loop Condition

Question 10

It updates the loop variable

Answer 10

Step Expression

Question 11

These are used to store multiple values in a single variable, instead of declaring separate variables for each value.

Answer 11

Arrays

Question 12

To declare this, define the variable type, specify the name of the array followed by square brackets and specify the number of elements it should store:

Answer 12

Array

Question 13

You can access an array element by referring to the index number inside _______

Answer 13

Square Brackets []

Question 14

These are like a row of boxes where you can store things where each box can hold one item, such as a number or a word. For example, in an array of numbers, the first box might hold 5, the second 10, and so on

Answer 14

1D Arrays

Question 15

In 1D Array, you can easily find or change what’s in each box by referring to its position, called an _______.

Answer 15

Index

Question 16

These are handy because they let you store lots of related data in one place and access it quickly.

Answer 16

Arrays

Question 17

You can loop through the array elements with the _______.

Answer 17

for loops

Question 18

This is introduced in C++ version 11 (2011), which is used exclusively to loop through elements in an array (and other data structures, like vectors and lists)

Answer 18

for-each loop

Question 19

you can iterate through an array by using an _______to access each element.

Answer 19

Index

Question 20

you don’t have to specify the size of the array. The compiler is smart enough to determine the size of the array based on the number of inserted values:

Answer 20

Omit Array Size

Question 21

It ______ operator is used to determine the memory size of types or objects in bytes.

Answer 21

sizeof operator

Question 22

It can help calculate the number of elements in a static array (an array whose size is fixed at compile time).

Answer 22

sizeof operator

Question 23

is essentially an array of arrays. It’s a way to store data in a grid or matrix format, where each element is accessed by two indices: one for the row and one for the column.

Answer 23

2D Array

Question 24

This structure is commonly used for tasks involving tables, grids, or matrices, like representing a chessboard, image data, or other tabular information.

Answer 24

2D Array

Question 25

It is a collection of two-dimensional arrays.

Answer 25

3D Array

Question 26

It can be visualized as multiple 2D arrays stacked on top of each other

Answer 26

3D Array

Question 27

It is an extension of a 2D array, where each element of it is accessed using three indices

Answer 27

3D Array

Question 28

It is an array that has more than one dimension, allowing you to store and manipulate data in a grid, table, or higher-dimensional structure. Each dimension represents a level of data organization, such as rows, columns, and layers.

Answer 28

Multi-Dimensional Array

Question 29

It is an array of arrays. To declare it, define the variable type, specify the name of the array followed by square brackets which specify how many elements the main array has, followed by another set of square brackets which indicates how many elements the sub-arrays have:

Answer 29

Multi-Dimensional Array
