单选题以下哪种初始化数组的方式是错误的？（）A String[] name =，“zhang”，”wang”，”li”-B String*3+ names=，“zhang”，”wang”，”li”-C String names[] =new String[3]  names*0+=”wang”D names*1+=”wang”E names*2+=”li”F 以上皆正确

It's very interesting to study names of different countries.Chinese names are different (1) foreign names.Once an English lady came to visit me.When I was introduced to her she said, “ Glad to meet you, Miss Ping.” Then she gave me her name card with three words on it:"Betty J.Black.So I said, “Thank you, Miss Betty.” We looked at each other and laughed heartily.Later I found that the English people (2)their family names last and the given names first, while their middle names are not used very much.I explained to her that the Chinese family name comes first, the given name last, so she(3) never call me Miss Ping.She asked if we Chinese had a middle name.I told her we didn't.but people may often find three words

on a Chinese name card.In this case the family name still come first, and the other words after it(4)a two-word given name.it is quite usual in China.My sister is Li Xiaofang.She has two words in her given name instead (5) just one like mine.(完型填空)

A.Put

B.From

C.Should

D.of

E.are

String s="zhang san,li si,wang wu"; 按字母顺序对姓名

定义结构体数组： struct stu { int num； char nameE20]； }X[5]={1，"LI"，2，"ZHAO"，3，"WANG"，4，" ZHANG"，5，"LIU")； for(i=1；i<5；i++) printf("％d％c"，x[i]．num，x[i]．name[2])； 以上程序段的输出结果为( )。

A.2A3N4A5U

B.112A3H4I

C.1A2N3A4U

D.2H3A4H5I
