10. Write a program to find factorial or a number. var number: Int = 5 // Change the number here var fact: Int = 1 var n: Int = number + 1 for i in 1..
Output: Factorial of 5 is: 120
11. Write a program to swap two numbers. func swap(a: Int ,b: Int) -> (Int,Int){ return (b,a) } var a: Int = 10 , b: Int = 20 print("Before swapping", a, b) var s = swap(a:a,b:b) print("After swapping ", s.0, s.1 )
Output: Before swapping 10 20 After swapping 20 10
12. Write a program to check palindrome number. var reverse = 0 var rem = 0 var num = 141 var n = num while num != 0 { rem = num%10 reverse = reverse * 10 + rem num = num/10 } if(n == reverse) { print("\(n)" + " is a palindrome.") } else { print("\(n)" + " is not a palindrome.") }
Output: 141 is a palindrome.
Output: Factorial of 5 is: 120
