Question

Does anyone know about this?

The chapter mentioned that systems analysts and programmers transform objects into program code modules. Modular design is a very popular concept in many industries. Can you give two more modular design examples? Explain each example briefly.

Answer 1

Modular design is a design that creates things out of independent parts with standard interfaces. This allows designs to be customized, upgraded, repaired, and for parts to be reused. A popular example of modular design are LEGO plastic construction toys.

Modular programming is a software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality.

The module is basically a set of interrelated files that share their implementation details but hide it from the outside world.

Modular Design Examples:

1. Using one function for taking in the program and using another program to display output.

class demo

{

public:

get(int x)

{}

set()

{}

}

2. Using various functions for calculating various types of areas in a single program.

int rectangeArea(int l, int b)

{

return l*b;

}

int circleArea(int r)

{

return 3.14*r*r;

}

In modular approach, we have used different modules/functions for different types of tasks/functions to be performed.
