What is Procedural Language and Non-Procedural Language
What is Procedural Language and Non-Procedural Language
All the instructions must be written in order and the user has to follow. All the instructions are executed one by one. It has a complete procedure that defines what to do and how to do it. All the instructions are written in a specific order to solve a particular problem. Language is very easily understood by a user because all the instructions are written in order.
Examples of Procedural Language
- FORTRON( formula translation)
- COBOL( common business-oriented language)
- C language
- basic( Beginners All-Purpose Symbolic Language)
Advantages of Procedural language
- It is easy to understand
- it is easier to test and debug
- it is a well-structured language
- Single Programs can be written by more than one program by dividing the program up into modules.
- It consists of a step-by-step procedure that is why it is easily understood by any user.
- These languages are very flexible.
Disadvantages of Procedural Languages
- A big disadvantage of procedural language is the inability to reuse the code.
- The same type of code many times throughout a program can add to the development cost and time of a project.
- Testing the program is very difficult.
- debugging is very difficult.
- It is not very fastly executed as compared to the low-level language code.
- Another disadvantage of Procedural language is that it struggled to handle the situation in which the number of possible actions may lead to the desired result
Non-Procedural Languages
In these languages, all the instructions are not written in a specific order. It is also known as a declarative and functional language. The non-procedural language that does not require writing traditional program logic. Users concentrate on defining the input and output rather than the steps of the program. Examples of non-procedural languages are as follows.
- Java
- C++
- SQL(Structured Query Language)
- RGP( report program generator)
Advantages of Non-Procedural Languages
- In non- procedural language The large program is easy to handle.
- The nonprocedural language program is written as a different function and modulus that interact with each other.
- These languages are easy to understand.
- these languages are used to write large Programs easily.
- The execution time is very fast.
Disadvantages of Non-Procedural Languages
- It is difficult to understand.
- it is not very flexible.
- For the large program, the code will become very complex
- The syntax of this language is not very easy.
Comparison of Procedural Languages and Non-Procedural Language
| Procedural Language | Non-Procedural Languages |
| command-driven language | functional driven language |
| It does not return any data type. if only return, then restricted data type and allow the values | it can return any data type or value. |
| its efficiency is high than non-procedural | Its efficiency is a low then procedural language |
| The program size is very large | the program size is very small |
| it is not suitable for time-critical application | it is ideal for time-critical |
| Loops and recursive calls are both used in procedural languages. | Recursive calls are used in nonprocedural language |
