Which of the following is a valid c++ array definition?
a.

b.
float $payments[10];
c.
void numbers[5];
d.

The correct answer for the given question is option(D) i.e int array[10];

Explanation:

As array is the collection of similar types of elements

we can declared array

Datatype arrayname[size];

In option(A) the size of array is 0 which is wrong thats why this option is wrong.

In option(B) the arrayname cannot start with ' $'  thats why this option is wrong.

In option(c)  we cannot give void datatype as a arrayname thats why this option is wrong.

So the correct option is(D) i.e int array[10];
