Data Types – Modifiers And Type Aliases

/*
  Primitive Data Types
  - Modifiers
  --- Modify The Length Of Data => See Limits

  ----- ٍSigned [int, char]
  -------- Store Positive, Negative Integers And 0
  -------- int Is Signed By Default

  ----- Unsigned [int, char]
  -------- Store Positive Only

  ----- Short [int]
  -------- Can Be short Instead of short int

  ----- Long [int, double]
  -------- Store Maximum Value
  -------- Can Be long Instead of long int

  - Type Alias
  --- using identifier = type;
  --- typedef unsigned long UL;
