C++ Arrays

What is Arrays

Array is a collection of the same type of data that is accessed by something named index. Index is number from 0 to array length. Array length is how many items are in the array.
Creating array

To create an array you specify type and name and then you use [] to mark it is array. Inside [] you specify how many elements array could hold.
```
// array of 5 integers
int numbers[5];   
```
To set array element you use name [] and inside the index.
```
// first element will be 0 because index is from 0 to array length
numbers[0] = 0;
```
To access value of array element you are using the same as setting element.
```
 int a;
 // a would be set to 0
 a = numbers[0];
```
The numbers itself is a pointer to first element of an array. You can access first element by dereferencing it using *. If you access array element that is not inside array you could get some bad errors and memory leaks so don't do it.
```
*numbers // 0
```
