On the basis of modular programming(moduler programming can b used to break up a large program in2 manageable units) the program is designed in top-down approach. As we go towards bottom, the task become simpler ans easy.....
The top-down design starts from the start of the program and tracks down all steps but the step wise refinement is backwards.
top-down design
C is often considered a top-down programming language because it encourages a structured approach to software development, where complex problems are broken down into smaller, manageable sub-problems. This method allows programmers to focus on high-level functionality before delving into implementation details, promoting clearer design and easier debugging. Additionally, C's modularity through functions supports this top-down methodology, making it easier to build and maintain large software systems.
It is a designing method, but has nothing to do with the C language. No its a very useful technique of C programming In top down stepwise refinement we start with a psuedocode (it is actually a puseudocode) First the "Top"...is a single statement, in effect the complete representation of programme. but cannot give all the details so we do some refinement We do refinements in steps, like specifing variables and then again refine them by intializing them with specific or desired numbers or values. So top down stepwise refinements make it easy for us to design a programme...we divide our program from top to down in segments and refine (or define) these segments.
what do we call the process of subdividing a problem into smaller sub-program.c programing
The fundamental difference is that in C++ object-oriented programming (OOP) was added. C is a procedural language (that means. top-down structure design), where as C++, which is an extension of C itself, is an object oriented language.
Top down Program Design : Begins the design with main or top-level module, and progresses downwards to the lowest level modules or subsystem Bottom down Program Design : Begins the design with the lowest level modules or subsystems, and progresses upward to the main program, module or subsystem.

C++ is a bottom-up language, not a top-down language. Objects act as the building blocks for all C++ programs, thus lower base classes must be defined before more complex data types can be built from them. C is a top-down language where everything is written procedurally, step-by-step. Thus to use top-down source code in C++, the code must be written using C-style conventions. Most C++ programs use a combination of object-oriented and procedural programming. It is rare to write an entire C++ program using C alone.

C is just the top three fingers of your left hand down with your thumb on the back.
Top down approach is based on Chip level flow, If the design is small then we can opt for this approach . Bottom down approach is hierarchical based chip design flow, If our Design is big, then , the chip is divided in to small manageable modules, it is similar to "Divide and Conquer approach", Finish the small manageable modules , so that the run time will be controlled, and then finally integrate in to one-chip.
