Variables in swift : syntax with example

In all types of programming languages a variable is a container which holds the value
while the swift program is executed. A variable is assigned with a datatype.
Variable is a name of memory location. 

Swift 6 has a specific type:

• Character
• Int or UInt
• Float 
• Double
• Bool
• String

Variable declaration:

Syntax : var variable_name = <initial_value>

Example : var int a = 10

print(a); 

Result : 10

Swift 4 also allows to define various other types of variables, which we will cover in another post 

such as Optional, Array, Dictionaries, Structures, and Classes.
