}
func markssecured() -> String {
return "(stname) has scored (marks)"
}
}
let studdet = classc()
studdet.stname = "Swift"
studdet.marks = 98
studdet.markssecured()
println(studdet.marks)
println(studdet.result)
println(studdet.present)
println(studdet.subject)
println(studdet.stname)
当我们使用 playground 运行上面的程序，得到以下结果。
98
true
false
