I installed Dev C++ on my PC ...its the first time I am using it.
Can somebody tell me how I can link and compile a .cpp and it's corresponding .h file to produce the required .exe ? I want to know how to build on Dev C++ basically.

I've never seen a compiler that does that. When using the outdated STL headers, the most you'll get is a warning (because they can't completely wash out old C++ support).
The .h form of header inclusion is still there for backward compatibility and there are many reason you shouldn't use them. This is what I got :
Although the <iostream.h> library was deprecated for several years, many C++ users still use it in new code instead of using the newer, standard compliant <iostream> library. What are the differences between the two? First, the .h notation of standard header files was deprecated more than 5 years ago. Using deprecated features in new code is never a good idea. In terms of functionality, <iostream> contains a set of templatized I/O classes which support both narrow and wide characters. By contrast, <iostream.h> classes are confined to char exclusively. Third, the C++ standard specification of iostream's interface was changed in many subtle aspects. Consequently, the interfaces and implementation of <iostream> differ from <iostream.h>. Finally, <iostream> components are declared in namespace std whereas <iostream.h> components are declared in the global scope. Because of these substantial differences, you cannot mix the two libraries in one program. As a rule, use <iostream> in new code and stick to <iostream.h> in legacy code that is incompatible with the new <iostream> library.
