Advantage and disadvantages of Structure and object oriented programming

In my last post, i discussed about structured oriented programming, object oriented programming and language processors. Today i am going to discuss about :-

 1. Advantages and Disadvantages of structured oriented programming.
2. Advantages and Disadvantages of object oriented programming.
3.Difference between them.

 And in the next post i will discuss about:-

 1. 1st C++ program and explanation.
2. Structure of a C++ program.
3. Data types, Identifiers, Variable and Keywords.

 Let's start:

 Advantages of Structure oriented programming:-
1. It is easy to understand.
2. It is to test a program that is divided into modules(sub-problem) and sub-module(sub-sub-problem).
3. Modification is easier.
4. It results in speedy execution of the program.
5. Development of modules is easier.

 Disadvantages of Structured oriented programming:-

 1. Modules occupy more space in the memory.
2.  Testing of every module is time consuming process.
3. Combination of modules becomes difficult for different design of modules.

 Advantages of object oriented programming(OOP):-

 1. Easy to understand.
2.The principle of data hiding helps the programmer to build secure program.
3.Through the use of inheritance(C++ feature) we don't have to write a code again and again that perform a specific task, And in this way we can use a code again when needed.  .
4.It provides a special feature in which we can use a module name  to different different purposes.

 Disadvantages of object oriented programming(OOP):-
1. The main disadvantage of OOP is that it is slower than a structure oriented programming.
2. Designing a program in OOP concept is little bit tricky.
3. The size of a OOP programming is larger than a structured oriented programming.

Structure oriented programming
Object oriented programming
Structure Programming is 

designed which focuses on 

process/logical structure and 

then data required for the 

process.
Object oriented programming 

is designed which focuses on 

data.

Structure programming follows 

top-down approach.

Object oriented programming 

follows bottom-up approach.


It is also known as Modular 

programming.

It supports inheritance,


encapsulation, abstraction, 


polymorphism etc.

In it a program is divided into 

small self contained functions.

In it a program is divided into 

small entities called object.

It can solve moderately 

complex programs.

It can solve any complex 

programs.

It provides less re-usability, 

more function dependent.

It provides more re-usability , 

less function dependent.

Less abstraction and less 

flexibility.

 More abstraction and more 

flexibility.

size and range of basic data types and modifing the basic types.

Size and range of basic data types:-   Modifying the basic types:-  Except for type void, the basic data types may have various modifiers preceding them.  You use a modifier to alter the meaning of the base type to fit various situations more  precisely. The list of modifiers is shown here: signed unsigned long short You can apply the modifiers signed, short, long, and unsigned to integer base  types. You can apply unsigned and signed to characters. You may also apply long to  double. The above  table shows all valid data type combinations, along with their minimal ranges and approximate bit widths. (These values also apply to a typical C++  implementation.) Remember, the table shows the minimum range that these types will  have as specified by Standard C/C++, not their typical range. For example, on  computers that use two's complement arithmetic (which is nearly all), an integer will have a range of at least 32,76...

C++ tokens, rule for naming variable and rule for constructing integer constant, real constant and character constant

 C++ character set :- The following image shows the valid character that are used in C++.  C++ data types:- 1st of all we have to know that What is a data? Data is a raw material for constructing a information. For example, the following list are the data:- Ram,17, XII C. And from this data we can construct the information as Ram Aged 17 years is in class XII C. Data may be any number,words, amount,quantity. Now, Let's come on the topic: Latter i will discus about 'structure', 'Union', 'Class', Array', 'function','pointer','reference' for now there are five basic data types that are: 1. int(integer)  2. char(Character) 3. float 4. double  5. void  Now look at variable:  Variable is a entity whose value may change and in programming language it is used to store data. A integer type variable can hold a integer number(number must be a whole number either in positive or in negative but not in fraction),  a ch...
