struct studentMarks { var mark1 = 100 var mark2 = 200 var mark3 = 300 } let marks = studentMarks() println("Mark1 is \(marks.mark1)") println("Mark2 is \(marks.mark2)") println("Mark3 is \(marks.mark3)") When we run the above program using playground, we get the following result: Mark1 is 100 Mark2 is 200 Mark3 is 300 Students marks are accessed by the structure name 'studentMarks'. The structure members are initialized as mark1, mark2, mark3 with integer type values. Then the structure studentMarks() is passed to the 'marks' with 'let' keyword. Hereafter 'marks' will contain the structure member values. Now the values are printed by accessing the structure member values by '.' with its initialized names. struct MarksStruct { var mark: Int
init(mark: Int) { self.mark = mark } } var aStruct = MarksStruct(mark: 98) var bStruct = aStruct // aStruct and bStruct are two structs with the same value! bStruct.mark = 97 println(aStruct.mark) // 98 println(bStruct.mark) // 97 When we run the above program using playground, we get the following result: 98 97
