How do you write an element in an array?
To create an array, define the data type (like int ) and specify the name of the array followed by square brackets []. To insert values to it, use a comma-separated list, inside curly braces: int myNumbers[] = {25, 50, 75, 100}; We have now created a variable that holds an array of four integers.
How do you view an array?
Another way to see arrays is to use the F9 key. If I carefully select just the range B5:B14, and then press F9, we see the original values. To undo this step, use control + z. Often, you’ll want to check the values in an array being passed into a function as an argument.

How do you use arrays?
About Array Formulas. Array formulas carry out calculations,such as addition and multiplication,on the values in one or more arrays rather than a single data value.
