1.

String:

不能连续拼接2个(或以上)字符串字面量。
P15,练习1-1:以下message定义有效

const std::string hello = "hello";
const std::string message = hello + ", world" + "!";
练习1-2:以下message定义无效,编译不通过
const std::string exclam = " ! ";
const std::string message = "hello"  + ", world" + exclam;

练习1-6:

	std::cout << "what is your name ?";
	std::string name;
	std::cin >> name;
	std::cout << "Hello, " << name << std::endl << "And what is yours ?";

	std::cin >> name;
	std::cout << "Hello, " << name << "; nice to meet you too!" << std::endl;
如果一次直接输入两个词(中间有空格隔开),如zhang san,输入如下:

Hello, zhang
And what is yours ?Hello, san; nice to meet you too!
