8.9. Using arrays when implementing loops.

The very concept of an array in the C language does not change. When declaring an array, the general name of the array elements, the dimension and its type are indicated.
Example:
int a [20];
In this case, the last element in the array will have an index of 19, since Numbering starts with zero. Appeal to a single element is organized by the name of the array and the index of the element.
Each line in the C language is a character array, but not every character array is a string. A string is an array, the last value of which will be the zero element.
