---------Write a swift program to accept two integer value and return true if one of them is 20.

func check(a: Int, b: Int) -> Bool { if a == 20 || b == 20 { return true } else { return false } }

let a = 21 let b = 22 if check(a: a, b: b) { print("One of them number is 20") } else { print("None of them number is not 20") }

--------Write a Swift program that accept two integer values and to test which value is nearest to the value 10, or return 0 if both integers have same distance from 10.

func nearestTo10(a: Int, b: Int) -> Int { let distanceA = abs(a - 10) let distanceB = abs(b - 10) if distanceA < distanceB { return a } else if distanceA > distanceB { return b } else { return 0 } }

let a = 15 let b = 5 let nearest = nearestTo10(a: a, b: b) print(nearest)

-------Write a Swift program to check if a given non-negative number is a multiple of 3 or a multiple of 5.

func isMultipleOf3Or5(number: Int) -> Bool { return number % 3 == 0 || number % 5 == 0 }

let number = 15 let isMultiple = isMultipleOf3Or5(number: number) print(isMultiple)

--------------Write a Swift program to compute the sum of the two integers. If the values are equal return triple their sum.

func sumOfIntegers(a: Int, b: Int) -> Int { if a == b { return 3 * (a + b) } else { return a + b } }

let a = 10 let b = 10 let sum = sumOfIntegers(a: a, b: b) print(sum)

---------Write a Swift program to add "Is" to the front of a given string. However, if the string already begins with "Is", return the given string.

func addIs(string: String) -> String { if string.hasPrefix("Is") { return string } else { return "Is" + string } }

let string = "Hello" let newString = addIs(string: string) print(newString) // "IsHello"

let string2 = "IsGood" let newString2 = addIs(string: string2) print(newString2)

------Write a Swift program to find the largest number among three given integers.

import Foundation func findLargestNumber(numbers: [Int]) -> Int { var largestNumber = numbers[0] for number in numbers { if number > largestNumber { largestNumber = number } } return largestNumber }

let numbers = [60, 20, 30] let largestNumber = findLargestNumber(numbers: numbers) print("The largest number is (largestNumber)")

------Write a Swift program to test whether the last digit of the two given non-negative integer values are the same or not. May 29, 2023 func lastDigitIsSame(x: Int, y: Int) -> Bool { let xLastDigit = x % 10 let yLastDigit = y % 10 return xLastDigit == yLastDigit }

let x = 10 let y = 51

if lastDigitIsSame(x: x, y: y) { print("The last digits are the same.") } else { print("The last digits are not the same.") }

-------Write a Swift program to accept two integer values and return true if one is negative and one is positive. Return true only if both are negative. May 28, 2023 func oppositeSigns(x: Int, y: Int) -> Bool { if x < 0 && y > 0 || x > 0 && y < 0 { return true } else { return false } }

let x = -2 let y = 11

if oppositeSigns(x: x, y: y) { print("The numbers have opposite signs.") } else { print("The numbers do not have opposite signs.") }
