Its quite hard to get people to help you with link errors, you know you spelt iostream wrong in your include, I dont think thats your only problem though... I will keep looking whats going on with standared lib.h I have never had to use that with the code your using?

you mixing c with c++?

you know you got to build header files and add them to the project, I know thats a built in lib but im confused...maybe im no help :/ sry

you also seem to have functions with no type, 2 functions with the same name and should be same return type even though 1 is missing the type and you should normally declare them before main or use a function prototype.

I am going to re-write this code and post it if it doesn't work also.
