The chop function chops off the last character of a string and returns the chopped character
The chomp function removes the last character of each element in a list if it ends with a newline and returns the number of newlines it removed.
# Chopping and chomping a list
@line=("red", "green", "orange");
chop(@line); # Chops the last character off each string in the list
print "@line";
@line=( "red", "green", "orange");
chomp(@line); # Chomps the newline off each string in the list
print "@line";
