Exercise 1.7:编译有不正确嵌套注释的程序。

#include <iostream>
int main()
{
	std::cout<<"Enter two numbers:"<<std::endl;
	int v1,v2;
	std::cin>>v1>>v2;
	std::cout<<"The value of "<<v1<<" * "<<v2<<" is ";
	std::cout<<v1*v2<<std::endl;
	return 0;
	// 
	 */
}

编译结果:

1>------ 已启动生成: 项目: HelloWorld, 配置: Debug Win32 ------
1>生成启动时间为 2011/11/24 11:54:59。

Exercise 1.8:

指出下列输出语句哪些(如果有)是合法的。

   std::cout << "/*";
   std::cout << "*/";
   std::cout << /* "*/" */;

预测结果,然后编译包含上述三条语句的程序,检查你的答案。纠正所遇到的错误。

std::cout << "/*";//正确
std::cout << "*/";//正确
std::cout << /* "*/" */;不正确,/*与*/必须匹配,最后一个*/没有与之匹配的/*
