C Sharp Tutorial ~ Part 1: The Theoretical Stuff
LiamDonohue (168)

Hello Guys!

It's what I promised!!

Ok, so today I'm going to introduce the theoretical stuff of C# (btw this Will be useful later).

Variables

What is a variable anyway?

Well, a variable is a reserved place in your (or in this case, repl's servers) computer's RAM (Ramdom Access Memory), that can be edited.

Types of Variables.

  • bool
    This can only hold 2 values, true or false
  • string
    This can hold multiple alphanumeric and special characters, such as
    "hello world"
  • char
    This can only hold a single alphanumeric character
  • Integer
    This can hold a single numeric value
  • double
    This can hold a single decimal value

    Notice!
    There are TONS more types then this but for the sake of space (and me being lazy lol), I'm not going to list them all.

Constants

These are basically just normal variables but they cannot be edited

Notice!
These are NOT declared normally
Example:

const string = "hello";

ERRORS

Ah, everyone just loves these! they are such a pain in the behind

SYNTAX ERRORS

A syntax error is a:

  • spelling error
  • missing character

LOGIC ERRORS

These are basically mathematical errors or misspelling of variables
Example:

You may be wondering: Why? it looks fine

Well, it's not. If you look closer it's simple. You just made a capitalization error

RUNTIME ERRORS

These are nearly undetectable
some signs are:

  • low memory
  • division by zero

Good Programming Practices

- Indentation

- Commenting

Example:
//this is a comment

well that's all for now
