these programs are for the basic understanding and interview asked these questions

(1) program to get reminder after divide by 3 in any number

func check(num: Int)-> Int{
    var n = num
    var result = n % 3
    return result
}
print(check(num: 1234))

OUTPUT:-
1

(2)smallest and largest if - else

func checknum(a: Int, b: Int)-> Int{
    if (a > b ){
        return a - b
    }
    else{
        return a + b
        }
}
print(checknum(a: 30, b: 40))
print(checknum(a: 50, b: 10))

OUTPUT:-

70
40

(3) ternary operator

func ternariy(a: Int,b: Int)-> Int{
    let result = a > b ? a - b : a + b
    return result
}
print(ternariy(a: 30, b: 40))
print(ternariy(a: 50, b: 10))

OUTPUT:-

70
40

(4)Program to print the percentage of the number

func percentage(Hindi: Double,English: Double, SS: Double,S: Double,Sanskrit: Double)-> Double{
    var per = (Hindi + English + SS + S + Sanskrit) / 5
    return per
}
print(percentage(Hindi: 23, English: 17, SS: 87, S: 23, Sanskrit: 43))

OUTPUT:-

38.6

(5) print count 1 to 10

var a = 1
while (a <= 10){
    print(a)
    a = a + 1
}

OUTPUT
1
2
3
4
5
6
7
8
9
10

(6) print count in the reverse order with the margin of 2

var b = 20
while(b >= 2){
    print(b)
    b = b - 2
}
OUTPUT
20
18
16
14
12
10
8
6
4
2
(7) Program print the sum of the number

func sumOfNumber(num: Int)->Int{
   var number = num
   var result = 0
    while(number > 0){
        var r = number % 10
         result = r + result
        number = number / 10
    }
    return result
}
print(sumOfNumber(num: 11111))
OUTPUT-
5

(8) program to print the product of any number

func productOfNumber(num: Int)-> Int{
    var  numbr = num
    var result = 1
    while(numbr > 0){
       var reminder = numbr % 10
       result = reminder * result
       numbr = numbr / 10
    }
    return result
}
print(productOfNumber(num: 43259))
OUTPUT:-

1080

(9) Program to find the factorial Number

func factorial(num: Int)->Int{
    var n = num
    var fact = 1
    if (n < 0){
        print("factorial is not possible")
    }else{
        while(n > 1)
        {
             fact = fact * n
            n = n - 1
        }
    }
    return fact
}
print(factorial(num: 5))

 OUTPUT:-

120

//10 program to convert binary into decimal

func decimal(num: Int)-> Int{
    var n = num
    var j = 1
    var dec = 0
    while(n > 0){
        var rem = n % 10
        var d = rem * j
         dec = dec + d
        j = j * 2
        n = n / 10
    }
  return dec
}
print(decimal(num: 1111))

OUTPUT:-
15

After doing all these 10 programs i am sure you get a little idea of the programming and start taking interest in the programming 

Thank you
