How to Use Map(string, char) template to create Hash Table?

The C++ library provides excellent features for creating a hash table.  The TI ARM compiler supports those features.  It would be better for you to learn about those features with material specifically dedicated to that purpose.

My first recommendation is the book The C++ Standard Library by Nicolai M. Josuttis.  Start with section 5.2.2 on Associative Containers. 

If you want something off the web right now, I recommend you search on c++ map associative array.  Those links look promising.

Thanks and regards,

In this environment I want to use map(string,char) template to create a Hash Table or else it will be huge lines of code if I do on my own.

But I don't know how. When I compile after I include map file in my main.c, compiler shows bulge error statements.

One thing you might try is to change the file from main.c to main.cpp.

The TI cgt is both a C and C++ compiler.  One convention is that files ending in ".c" are treated as C files, files ending in ".cpp" are C++ files.  Because the STL is part of the C++ standard library, you will want a C++ extension for the the file.
e.g. main.cpp

#include <map>
int main()
{
  std::map<int, int> m;
  return 0;
}
