Hi All,
How do i check whether a range is empty. eg.
(!PFResutl.toRange).empty. I tired the below, but it is no printing
Empty if the range is empty it just prints blank line.
if (!(!PFResutl.toRange).empty) { writeln("Empty"); }
Without knowing what PFResutl is, let me simplify a bit:
if( ! (expr).empty) { writeln("Empty"); }
That exclamation point means "not". So you are first checking if the
range is NOT empty, and if so, printing "Empty". Is that what you meant?
