Choose a correct C statement to choose number 26 in the array,

int arr[3][3] = { {11,22,44}, {33,44, 26}, {55,66, 78} };

a. arr[1][3]

b. arr[3][2]

c. arr[1][2]

d. All of the above

$\huge \text{Required \: Answer}$

c. arr[1][2]

$\large \text{Required \: Explanation - }$

Declares arr as two - dimensional array , which contains 3 row and 3 columns and can be shown as follow :

• C stands for column
• R stands for rows

⠀⠀⠀⠀⠀C 0 ⠀⠀⠀C 1⠀⠀⠀⠀C2

R 0⠀| ⠀[0][0]⠀|⠀[0][1]⠀|⠀[0][2]⠀|

R 1⠀|⠀[1] [0]⠀|⠀[1] [1]⠀|⠀[1] [2]⠀ |

R 2⠀|⠀[2][0]⠀|⠀[2][1]⠀|⠀[2][2]⠀|

⠀

Let's initialise a our two dimensional array

⠀⠀⠀⠀⠀C 0 ⠀C 1⠀⠀C2

R 0⠀| ⠀11⠀|⠀22⠀|⠀44⠀|

R 1⠀|⠀33⠀|⠀44⠀|⠀26⠀ |

R 2⠀|⠀55⠀|⠀66⠀|⠀78⠀|

⠀

now we can see that

• [0][0] = 11
• [0][1] = 22
• [0][2] = 44
• [1] [0] = 33
• [1] [1] = 44
• [1] [2] = 26
• [2][0] = 55
• [2][1] = 66
• [2][2] = 78

⠀

In the question we can see that we need to choose the correct C statement which is showing us number 26 and the C statement which is showing as 26 is [1] [2] = 26 ; hence the correct option is option c.

Answer 2

Answer:

option c is the correct answer.

c.arr[1][2]

Explanation:

because 26 no. arrray lies in arr[1][2]

and in arr[1][3] and arr[3][2] dont exist
