Im using the String lib. Im trying to delete the last character in the string.

using inString.append a can add a char to the string then the command inString.length() shows me the current length of it. I don't know if the left() command is in this lib or not. The combo of this will get me where i need to be i believe.

lol this doesnt work: inString.length() = inString.length() - 1

what is the delete last char command pls.

Try

inString.setCharAt(inString.length() - 1, '\0');

or

inString = inString.substring(0, inString.length() - 1);

cool. funny how after i see it it seemed so simple. i tried the first one but with and empty char. makes sense to use the terminating char there.

2nd answer was right infront of my face and i kept looking over it....

thanks

You've probably already found out that there is no empty char!

I think the second solution is the more correct here.
The first is how I'd do it in 'C', but may upset the String class.

hmm another ? ill start a new thread though.

thanks again
