boost::shared_ptr 的作为参数传递，以及构造细节！

代码如下：

#include <iostream>#include <boost/shared_ptr.hpp>#include <boost/make_shared.hpp>void funcx(boost::shared_ptr<int> c, int b) {std::cout << "after: " << "&c " << static_cast<void *>(&c) << ", "<< "c.get() " << static_cast<void *>(c.get()) << ", "<< "&b " << static_cast<void *>(&b) << std::endl;}int main(int argc, char *argv) {int a = 2;int b = 3;boost::shared_ptr<int> c = boost::make_shared<int>(a);std::cout << "first: " << "&c " << static_cast<void *>(&c) << ", " << "c.get() " << static_cast<void *>(c.get()) << ", "<< "&b " << static_cast<void *>(&b) << ", "<< "&a " << static_cast<void *>(&a) << std::endl;funcx(c, b);system("pause");return 1;}

输出结果如下：

first: &c 003FF988, c.get() 004B0A04, &b 003FF998, &a 003FF9A4
after: &c 003FF444, c.get() 004B0A04, &b 003FF44C
请按任意键继续. . .
