Answer 1

c++中输入一串字符的函数有多种：

C标准函数，存储字符到字符数组中：

char str[100];

scanf("%s", str ) ; //读入一串字符，不能包括空格

gets(str); //输入一行字符，可以有空格，以回车键结束

C++函数，可以存储到字符数组，也可以存储到string类对象中：

string str;

cin >> str ; //读入一串字符，不能包括空格

getline(cin,str ); //输入一行字符，可以有空格，以回车键结束

Answer 2

读取成C类型字符串，const_cast去掉const属性，编写方法倒置i到j之间字符，利用空格所在位置，调用这个方法，倒置所有单词，输出C类型字符串来自：求助得到的回答

Answer 3

先分割字符串，然后每个字符串从后往前输出

Answer 4

cin>>你的字符串的名字；如：
string str；
则cin>>str;

Answer 5

char a[10]
cin>>a;
