We are running code on a robot using multiple sensors and needing to see if something is possible.

Using Dexter industries GPS and NXTBee radio

GPS creates longs for longitude and latitude

I am wanting to create either a string combining the word longitude and the longitude long

And then need to either be able to move through that string one character at a time or convert it to an array of characters.

For people who are familiar with Java - I am looking to see if something like stringname.charAt(location) will return a character

The same can obviously done going through an array of characters one index at a time

The NXTBee will send 1 character at time time easily enough and I can not find a way to send a number or a string as one piece.

Ideas???

Working with students on a tight timeline so any help will be appreciated

char strIndex(const string &sString, const short nIndex); may be the function you're looking for.
You can also "convert" the string to a char array by simply copying it with memcpy();

Make sure the array is large enough to hold the string

Thanks for quick response - the string and char part I understand now.

Will Robot C let you copy a long into a string?

You mean convert it to ascii? sure, just use snprintf()

So I can copy a long into a string

task main()
{
string message;
long longitude = 10234161;
wait1Msec(1000);
snprintf(longitude, message); or did you mean sprintf(longitude, message);


}

snprintf(ppDest, nDestLength, pzFormatString, ...); is the call, you can also use sprintf, if you don't want to specify the max length of the receiving buffer:

Btw, do not cross post in multiple sub forums. I have deleted the other post.
