C# (C Sharp)

Question 1

Variables declaration in C#

Answer 1

Unlike C++ or C there is no need to declare a variable with a specific datatype.

Instead we use:
var ___

Question 2

Resilience of C#

Answer 2

C# will not crash if we try to access elements outside of the array, eg if array has 3 elements and we try to access element 5.
It also won’t crash if we define 2 variables, yet we call out 3. The third one will be set to zero.

Question 3

What happens at compile time

Answer 3

The code is turned into “Assembly” files. Intermediate Language file is created.

Note: CPU doesn’t understand those files.
The files need to be converted to binary code through an Execution Engine.

Execution Engine compiles the binary file on a JIT (Just-in-Time) basis.

Question 4

Common Language Runtimes (CLR)

Answer 4

.NET 6 (Cross platform)
.NET Framework (legacy version, specific to Windows)

Question 5

Base Class Libraries (BCL)

Answer 5

Libraries included in C#
