"Use strict" is one of the pragma used for checking the
variable scope and syntax. If you use this pragma means,
you need to specify the scope (my, local, our) for the
variable and use the exact usage of operators.
For eg. Checking equality $number = 1 and $char eq 'a'.

Answer / savitha sridhar
strict is a pragma that can be used to enforce Strict
programming practices while you write your programs.
Eg: You can write a program like this:
$x=100
print $x
But if you use strict pragma, then you have to be very
specific while using variables
use strict;
my $x=100; ##look at the usage of scope like my,local,our
print $x;
Pragma usage can also be used as a toggle
use strict;
my $x=100;
print $x;
no strict; # to toggle strict to "No"
$y=200; ##no need to use scope as strict is disabled
print $y;
