Error while trying to use a “map” design

Hello,
I am new in C programming and need help. I was trying to use a “map” design. It’s a lot like a dictionary throughout Python or Objective C, where the map design provides key/value pairs and CCStudio showed some errors as follows:
fatal error #5: could not open source file "map.h"
Here is a screenshot to the errors:

I think, I’m not referencing the package of map properly. Since I am a newbie, I am asking help from the experts.
Any assistance with this will be so helpful.
Thanks.
