I'm using keil mdk V5, I included "string.h" but I still cannot use string, I get "error: use of undeclared identified 'string' message , anyone knows whats wrong with it?
Could you perhaps show some code?
Are you compiling as C++ code?
I'm using default arm 5 c/c++ compiler, as for the code it doesn't matter as even in new blank project I get same error.

You understand that C and C++ are different languages?
You have to select one or the other:

C++ has a 'string' type; C does not.
Hence Westonsupermare Pier's question:

If you want to use 'string', you must compile as C++ - it will not work as C !
That is most likely my issue since I never checked it out... but I cant seem to find where I can select compiler, could you tell me how I can do it?

It's a single compiler - but it can be configured to treat your source as either C or C++
By default:
Or you can use one of the options described in the link I gave to set it explicitly:
I changed it to c++ but I keep getting the exact same error, any idea what else could cause the issue?
"string.h" is a C include file. It gives you the standard C "string" (array of NULL terminated chars) functions. It has no type or class called string.
<string> will give you the C++ string stuff.
