Difference between Procedural and Non Procedural Language

The procedural languages follow sequences of statements as instruction and therefore require to write more code and also the statements can be executed faster as they are more memory efficient. The non-procedural languages are domain-specific and are developed to fulfill one single purpose and their syntax is more to read and understand which makes it less prone to error and easy to learn. It can also perform higher complicated tasks that their domain requires.

 

Difference between Procedural and Non Procedural Language

PROCEDURAL NON PROCEDURAL
The procedural language is written as a series of instructions The non procedural language are written natural language instruction
In this language, the programmer has to provide instructions about what is to be done and how it is to be done In this language, the programmer does only provides information about what is to be done only
The procedural language are more command-driven The non procedural language are more function-driven
The return function can only be applied to certain data types The return function can support any data types and values
The length of the procedural programing language is more than non procedural because they have a less predefined library and class The length of the non procedural programming language is less as due to the presence of rich library and classes
These languages are more memory efficient These languages are less memory efficient
These language semantics includes characters, mathematical operator, etc which makes it better than assembly language which used mnemonic codes This language semantic includes natural language are very simple for a programmer
The procedural programming language is focused on an approach for solving the problem The non procedural programming language is domain-specific such as database, web development, etc
The procedural programming can support simple mathematical instructions The non procedural programming language can support complex mathematical instructions
This language support both the iterative loops and recursive calls  This language support only recursive calls
The memory location changes as the next statement are executed The same memory location can execute a series of instruction
It depends on the order of execution It depends on the values of the parameter from the function
The reuse of the code concept is not much developed The reuse of the code concept is present 
They can execute faster and they require less resource to compile and interpret They can execute slower because of so many libraries and classes 
The example of procedural language involves Fortran, Cobol, Fortran, basic, etc. The example of non procedural language includes java, SQL, C++, etc.
