push @powers, 2**$_ for 0..7;
sub bases {
for (@_) {
sprintf ("%08b", $_).
sprintf ("%4d", $_).
sprintf ("%4o", $_).
sprintf ("%4X", $_).
"\n";
}
}
print bases @powers;
--------------------------------------------------------------------------------------
I'm learning about Networking and wrote this to display ways numbers can
be represented.
My question is:
How can the 'for' loop within bases() output a list for 'print' as
invoked in the last line of code?
I've tried to using return() in the for loop, but that exits the bases()
too soon.
Some solutions: (1) put the print within the bases(). (2) push() into
an array and then iterate over for printing. --- These work but I am
wondering if there is a way to return() a list from the for-loop?
TIA,
Alex Gill
