Answer 2

Array is.. smth like.. many data collected in one variable. For example:
int i1 = 1;
int i2 = 2;
int i3 = 3;
int i4 = 4;
int i5 = 5;

That's not convenient to declare new variable every time. So we have easier way to do it. Just use array

Example above equals only one string:
int arr[] = {1,2,3,4};

Answer 3

An array is a fixed-length container.

Example :
std::array<int, 3> arr{ 1, 2, 3};

Here, arr is an array of 3 integers.
