Operator Archives - Ashish Kakkad

I was just going through the Swift document and I found that Swift allow to overload the operator just like as C++ Language. Objective-C doesn’t allow to overload the operator.
As swift document we can also say “Operator Functions”.

Let’s Overload ^ (XOR Operator) to make Power of the value

Function Prototype :
Declare function prototype with left hand side value and right and side value.

func ^(lhs: Int, rhs: Int) -> Int {
}

1 2	func ^(lhs: Int, rhs: Int) -> Int { }

Operations in the function :
To make the power of the value we have to apply following operations

func ^(lhs: Int, rhs: Int) -> Int {
    if(rhs == 0) {
        return 1
    }
    else {
        var result = lhs
        for _ in 1 ..< rhs  {
            result *= lhs
        }
        return result
    }
}

func ^(lhs: Int, rhs: Int) -> Int {

if(rhs == 0) {

return 1

}

else {

var result = lhs

for _ in 1 ..< rhs {

result *= lhs

}

return result

}

Let’s try to use with the operator :

let a = 2^2 //4
let b = 2^4 //16
let c = 3^3 //27

let a = 2^2 //4

let b = 2^4 //16

let c = 3^3 //27

Happy Coding 🙂
