In the previous tutorial, we used datatypes like `int`

, `float`

and arrays of characters inside the structure.

Besides those C also permits the use of arrays as elements that can be one-dimensional or multi-dimensional of any type.

In this tutorial, you will learn about the association of **c programming structure and arrays**.

### Example of arrays within structure

```
struct car_model{
char car_name[20];
int model[5];
} cars[3];
```

Here in this example `model`

contains 5 elements `model[0]`

, `model[1]`

, `model[2]`

, `model[3]`

, `model[4]`

and three struct variable `car`

also has 3 elements `car[0]`

, `car[1]`

and `car[2]`

. Those structure elements `model`

can be accessed as following:

`car[0].model[3];`

## Arrays of structures

In C, we can also create an array of structure variable where each element of the array will represent structure variable.

It is same like a multidimensional array with each array element holding structure variable which contains data of different datatypes.

Consider following example:

```
struct car{
int carnum_1;
int carnum_2;
};
int main()
{
struct car numbers[2] = {{22,34},{54,88}};
}
```

In above example, we have declared an array of structure variable called `numbers`

which contain 2 elements `numbers[0]`

and `numbers[1]`

. Here each element is initialized and can be accessed as following:

```
numbers[0].carnum_1 = 22;
numbers[1].carnum_1 = 34;
numbers[0].carnum_2 = 54;
numbers[1].carnum_2 = 86;
```
