Overview: Arrays in perl

You have been using arrays in perl for some weeks now, however all of these arrayshave been populated by calling a function from Text::CSV. We have not modified thecontents of the array ourselves.

You can add elements to an array in perl using the push function.

For example, the following code creates an empty array, and then adds two valuesto it: sub printArrayContents {

Lab5/CIS*2250 # placemy @array_argument = @_;the f i r s t argument into the variable @array_argument

printArrayContents ( @list_of_values ) ; push( @list_of_values ,printArrayContents ( @list_of_values ) ;”one “); push( @list_of_values ,printArrayContents ( @list_of_values ) ;”two “);

Note thethe order of any of the other values.push function adds the new value to the end of the array, without disturbing
