Comparison Operators | Swift Programming Language Tutorial

We can compare values of two operants (variables) using Comparison operators.

When you compare values using these operators the result is a Boolean value i.e true or false.

Example :


//

var a = 2
var b = 2
var c = 10

//Equal to
println("1. a == b : \(a == b)")
println("2. a == c : \(a == c)")

//Less-than
println("3. a < c : \(a < c)")
println("4. c < a : \(c < a)")


//Greater-than
println("5. a > c : \(a > c)")
println("6. c > a : \(c > a)")

// Less-than Equal
println("7. a <= c : \(a <= c)")
println("8. c <= a : \(c <= a)")

//Greater-than Equal
println("9. a >= c : \(a >= c)")
println("10. c >= a : \(c >= a)")

//Not Equal
println("11. a != c : \(a != c)")

Output :

1. a == b : true
2. a == c : false
3. a < c : true
4. c < a : false
5. a > c : false
6. c > a : true
7. a <= c : true
8. c <= a : false
9. a >= c : false
10. c >= a : true
11. a != c : true
