Terminology

Term	Definition
Flow Control Statements	When manipulating data in a C# app logical flow control statements preform actions depending on their function ie. `if`, `else`, `switch`, `while`.
`if` and `if else`	A logic statement that if a boolean condition is true then execute the code within the if statement. The `if else` statement is used to execute code if the `if` statement is true, and if it isn't true the `else` statement is run.
Equality	`==` is used when comparing two variables and if the variables are the same it would be a true statement.
Inequality	`!=` is used when comparing two variables and if the variables are not the same it would be a true statement.
Greater than	`90 > 60`
Less than	`50 < 60`
Greater than or Equal to	`total >= 90`
Less than or Equal to	`total <= 90`
Boolean AND	`&&` is used between two separate logical comparisons that will run code if both statements are true. `if(total < 100 && total != 0)`
Boolean OR	`
`switch` statement	When comparing a variable to multiple different cases `switch` statements are a cleaner alternative to `if else`.
`while` loop	When executing code that needs to continue running over and over until the condition in the while loop is true. For example: `while(reading) {Console.WriteLine("I'm being read")}` if reading becomes false there is nothing written to the console.
