String to 1 and 0

[tintin_99]

Hi,, how can I convert a string constant containing 1 and 0 to 1 and zero

for example if the string is 1010000 then the it should be converted to 1010000 in (0,1) format. Somthing like Boolean array to (0,1) block

Thanks

Try the Scan From String function with "%b" as the 'format string' input.

Hello Tintin_99,

I'd be surprised if there wasn't a function for this in the MGI or OpenG libraries, but as I don't have access to those at the moment to check here's a quick and dirty solution.  It's probably not the most efficient way to do it.

-edit-

As Darren indicated, Scan from String with a Boolean format specifier is the straightforward and easy to interpret later way- specifying a width of 1 and building an array out of the resulting outputs will give you the array of zeroes and ones (this is what I did in that screen capture).

You need to be more specific, because (0,1) is not a format.

If you know the string is clean (only 0 or 1, no weird characters), you can do the following.

This is a rarity, so I have to jump on it.

Christian's code can be simplified by subtracting 48 instead of comparing.  Again, this assumes that your string is nothing but ASCII 0 and 1.

Well, let me jump a little higher then. 😄

Why do math at all (yes, subtraction is hardcore math!) if all we really need is some cheap bitwise operation??? 😮
