How can I read the following tabular information about students scores from an input file and represent it in a hash in a perl program and how would I make reference to a particular score using name and score as keys.
Name reg score1 score2 score3 score4
a 1 2 3 3 4
b 2 4 5 6 7
c 3 5 6 7 9
d 4 6 0 2 8
e 5 0 9 5 3
