Answer Posted / prabin kumar, xansa(ind) chenn
"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'.
