Let's say you have an array of fruit that contains apple, banana, orange, and grape.

@fruits = qw(apple banana orange grapes);

Push can be used to add values to the end of an array. In this example, pineapple is added to the fruits array.

push @fruits, 'pineapple';

The array can be printed.

print @fruits;

Printing the array will show that "pineapple" has been appeneded to the end of the array.
