swift 学习笔记(12)-区间运算符

区间运算符(…),一般用于 for 循环

//1~10 包括101...10for index in 1...10{    print( index)}

//半开区间运算符//1~10 不包括10for index in 1..<10{    print(index)}

var names = ["name1","name2","name3","name4","name5"]names[1...3]for index in 0 ..< names.count{    print("name:\(names[index])")}names[0...1] = ["zhangsan","lisi"]print(names)
