Answer 1

7) Value contains the lowest value in array1.

explanation:-

each time value parameter get update when it compare array smaller values

8) 38

explanation:-  x [22, 33, 44]

FOR EACH value in a

    a[i] ←a[i] + 5

so x [27,38,49]

so x[1]=38

9) A reference to the string "ghi"

10) [1][1]

11)

Creates a 2D array with 30 rows and six columns

12) 13

matrix after execution is:-

3 5 7 9

11 13 15 17

19 21 23 25

13) Create array myNums[5][12]
