Explanation / Answer

You have not specified which language you want this program to be written in. But, inferring from your Hint to use the three-argument form of split(), I guess its perl. So, here is perl program to do so.

#!/usr/bin/perl

open(DATA,"<dictionary.txt") or die "Can't open the file";
@lines = <DATA>;
close(DATA);

my %dict;
foreach $line (@lines) {
   my @word = split(/ /, $line, 2);
   $dict{$word[0]} = $word[1];
}

print "Enter the word you want to look up in the dictionary: ";
my $input = <STDIN>;
chomp $input;

if( exists($dict{$input} ) ){
   print "$input:- $dict{$input}";
}
else {
   print "$input not found in the dictionary."
}
