Objective
To divide and subdivide the problem into logical modules. The modules are written in C as manageable and meaningful units called functions.
The concept of modular programming was introduced in Chapters 1 and 2. Large and complex engineering and scientific problems require many lines of code to solve them. It is difficult for a programmer to write the code of a long program as a single unit or to debug and maintain a long program as a single unit. It is easier to find logic and execution errors in short modules. When ...
