Write a swift programming code to perform following tasks a) declare a variable that stores the age of a person b) declare a constant that stores the earth gravity 9.8

Here we use the shift programming  code

(a)var age1: Int=24

(b)let ear_grav:Float=9.8

Explanation:

(a) To declared any variable in swift we follow following syntax

Syntax:var variableName = <initial value>

var age1: Int=24

Here age1 is a variable that stores the age of a person

to print this use we print command in swift

print(age1)

(b)To declared the constant in swift we follow following syntax

Syntax: let constantName = <initial value>

let ear_grav:Float=9.8

Here ear_grav is a constant that stores the earth gravity 9.8

to print this use we print command in swift

print(ear_grav)
