C++ Arrays
Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value.
To declare an array, define the variable type, specify the name of the array followed bysquare brackets and specify the number of elements it should store:
We have now declared a variable that holds an array of four strings. To insert values to it, we can use an array literal - place the values in a comma-separated list, inside curly braces:
To create an array of three integers, you could write:
Access the Elements of an Array
You access an array element by referring to the index number inside square brackets[].
This statement accesses the value of thefirst element incars:
Example
cout << cars[0];
// Outputs Volvo
Note: Array indexes start with 0: [0] is the first element. [1] is the second element, etc.
Change an Array Element
To change the value of a specific element, refer to the index number:
Example
cars[0] = "Opel";
cout << cars[0];
// Now outputs Opel instead of Volvo
