#Pattern Programming using Swift Programming language.

swift is new programming language come in market in 2014. it is developed by the developers of apple Inc before swift , iOS developer use objective c to develop the application , in 2014 apple came in marker with swift and start working with swift , as we see swift is new in market  and growing day by day now developer use swift frequently because swift provide many feature that is not present in objective c but that is not today topic .

Today topic is pattern programming , in interview for the fresher label company frequently asked to make a pattern and there is a company who came in campus for iOS developer position asked to make a pattern and you use swift as a language your impact is going good on the interviewer.

you can use any language logic will be same the only difference in the syntax. 

here are some basic pattern program and one program form the array . take a look and partice all the pattern these program are very easy. every cs student should know these program.

(1) func patternone(a: Int){

for i in 1...5{

    for j in 1...i{

        print("*", terminator:"")

    }

    print("\n")

  }

}

print(patternone(a: 5))

Output:-

(2)func patternTwo(lineYouWant: Int){

    for i in 1...lineYouWant{

       for j in 1...i{

          print(j, terminator:"")

        }

        print("\n")

    }

}

print(patternTwo(lineYouWant: 6))

Output:-

1

(3)func patternThree(lineYouWant: Int){

    for i in 1...lineYouWant{

        for j in 1...i{

            print(i, terminator:"")

        }

        print("\n")

    }

}

print(patternThree(lineYouWant: 6))

Output:-

(4)func patternFour(lineYouWant: Int){

    for i in 1...lineYouWant{

        for j in 1...i{

            print(i + j,terminator:"")

        }

        print("\n")

    }

}

print(patternFour(lineYouWant: 6))

Output:-

(5)func patternFive(linesYouWant: Int){

    for i in 1...linesYouWant{

        for j in 1...i {

            var m = i + j

            if(m % 2 == 0){

                print("1",terminator:"")

            }else{

                print("0",terminator:"")

            }

        }

        print("\n")

    }

}

print(patternFive(linesYouWant: 5))

Output:-

(6)func patternSix(linesYouWant: Int){

    var N = 1

    for i in 1...linesYouWant{

        for j in 1...i{

            print(N,terminator: "")

            N = N + 1

        }

        print("\n")

    }

}

            print(n,terminator:"")

            n = n - 1

(10) Swift program to print the sum of the array:-

func ElementInArray(input: [Int]){

    var array = input

    var sum = 0

    for i in array{

       sum = sum + i

    }

    print(sum)

}

print(ElementInArray(input: [1,2,3,4,5]))

Output:-

15

(11)func patternTen(outerLine: Int){

   for i in 1...outerLine{

        for j in 1...outerLine + 1 - i{

            print(i,terminator:"")

        }

        print("\n")

    }

}

print(patternTen(outerLine: 5))

        }

        print("\n")
