Answer 1

Answer:

iv only is the correct option

Answer 2

Number length

Explanation:

iv)Number length is 10

when an array gets initiated and declared

the size gets allocated to the array at the beginning

and all the elements are 0 s if we made equal an entire array into 0

like  :

int arr[10]=0;

it denotes that all elements of the array are zeroes

so here we did not declared to 0

so the size of the array is 10

so here array.length gives 10  

the answer is :

number length is 10
