interpreter compiler?

The main differences between an interpreter and a compiler are that:

•   interpreters will execute code as you go
•   compilers will run through the entire code and highlight mistakes if it won't allow it to run.
•   interpreters can be 2 - 10 times slower

Compiler < just in time compilation < interpreter

(ease of use)

compiler > just in time compilation > interpreter

(speed)

C# is a just in time compilation

Programming phases:

• Define a task/ problem - specification
• Plan your solution (find suitable algorithm to solve it or data structures to use) - design
• Write code - implementation
• Fix program error (bugs) - testing and debugging
• Make your customer happy - deployment

.NET framework

Common execution engine of many languages, e.g.: C++, C#.

Common Language Runtime (CLR)

Automatic memory management (garbage collection).
