Perl: printing an array
The tutor continues about Perl arrays with another trick.
For background, the reader can look up yesterday’s post. The main idea is that an array is a list of values.
Let’s imagine an array declared as follows:
@arr0=(“milk”,”eggs”,”bread”);
To print @arr0 one could use the command
print @arr0;
However, the elements would not be spaced apart; the output would be
milkeggsbread
The same command, but with @arr0 in quotes:
print “@arr0”;
will print the items with spaces in between:
milk eggs bread
