c++c++11smart-pointers 7 注意代码 ... { int* p = new int(0); std::unique_ptr<int> q(p); ... // make use of 'p' } ... 在上述代码中,唯一的指针q仅用于在必要时释放p。 Q本身没有被使用。 由于在声明之后从未在该行以下使用过q,因此似乎可以立即释放q,从而使得p出现“在释放后使...
make_shared 是 C++11 中的一个函数模板,用于创建一个 shared_ptr 对象,它可以避免使用 new 运算符,从而避免了内存泄漏的风险,其次因为STL库和boost库里的智能指针,是不同类型的,在不同作用阈空间的, 基础用法:

In C and C++ programming, pointers are very powerful. As we explained inC pointers examplearticle, pointers are variables that hold address of another variable so that we can do various operations on that variable. Sometimes a programmer can’t imagine writing a code without using pointers, wheth...
The reason this cannot be done in Java is that we have no guarantee over when the object will be destroyed, so cannot guarantee when a resource such as file will be freed. Onto smart pointers - a lot of the time, we just create objects on the stack. For instance (and stealing an ex...
