- Diff between Compiled Lang Vs Interpreted Lang Vs Declarative Lang?
complier lang
- Takes entire program as single input and converts it into object code which is stored in the file.
- Intermediate Object code is generated
- e.g: C,C++,java
- Compiled programs run faster because compilation is done before execution.
- Memory requirement is more due to the creation of object code.
- Error are displayed after the entire program is compiled
- Source code —Compiler —Machine Code —Output
Interperted lang
- Takes single instruction as single input and executes instructions.
- Intermediate Object code is NOT generated
- e.g: Perl, Python, Matlab
- Interpreted programs run slower because compilation and execution take place simultaneously.
- Memory requirement is less.
- Error are displayed for every single instruction.
- Source Code —Interpreter —Output
It’s a method of programming based around describing what something should do or be instead of describing how it should work.
- ex:xhtml, html
- Its advantages include effective code, which can be applied by using ways, easy extension, high level of abstraction, etc.
