This is the first program I made. It's relatively simple but it helped me understand the basics.
print "What is your name?";
my $name = <STDIN>;
print "Hello, $name:)\n";
print "How old are you? ";
my $age = <STDIN>;
print "You are $age years old!\n";
$age = $age / 2;
print "Half your age is $age years.\n";
print "Enter a number... ";
$sum = <STDIN>;
if (! isNumber ($sum))
print "Please use numrals.\n";
my $nextsum = $sum / 2;
print "Half of $sum = $nextsum";
my $value = shift;
return $value =~ /^[.\d+-eE]+$/;
print "\nTell me $name, would you like to try a test? Yes or No.\n";
my $answer = <STDIN>;
if ("no" eq lc ($answer))
print "Oh well, have a good day!";
if ("yes" ne lc ($answer))
print "Please answer yes or no $name\n";
print "The question is: What is the square root of 36?\n";
my $answertwo = <STDIN>;
print "Correct! Have a good day!" if "6" eq lc ($answertwo);
print "Sorry, you're wrong. Have a good day!" if "6" ne lc ($answertwo
As you can see, it goes like this:
What is your name?your name
Hello, your name:)
How old are you? 34
You are 34 years old!
Half your age is 17 years.
Enter a number... 5
Half of 5 = 2.5
Tell me your name, would you like to try a test? Yes or No.
The question is: What is the square root of 36?
Sorry, you're wrong. Have a good day!
