STL Hey, c + + long time no see, meet you again familiar and strange. The feeling of practicing many brush questions fades a little, and you need to be familiar with the actual questions again. This article will be continuously updated Today, let's remedy the concept of STL in time to facilitate more efficient problem brushing in the future. ...

1. Basic concepts Polymorphisms fall into two categories Static polymorphism: function overloading and operator overloading belong to static polymorphism and reuse functionsDynamic polymorphism: derived classes and virtual functions implement runtime polymorphism Difference between static polymorphism and dynamic polymorphism Statically poly ...

Through the disassembly code, see if you can see the address of a reference variable to know whether it occupies memory space. Test code: int main(){ int num = 6; int &r = num; int *p = # int x = r; int y = *p; return 0; } 1. X86-64 platform Obtain the disassembly code of the main function through GDB or ...

Feasible pruning Cut down unnecessary subtrees on the search tree through some judgment. Sometimes, we will find that the subtree state corresponding to a node is not the result we want, so we don't need to search this branch. Cutting off this subtree is pruning. Once the final solution of some states can not be found in any case, it can ...

preface The full name of SSDT is System Services Descriptor Table. This table is a link between the Win32 API of Ring3 and the kernel API of Ring0. SSDT not only contains a huge address index table, but also contains some other useful information, such as the base address of the address index, the number of service functions and so on. By modi ...

vector Vectors are sequence containers that represent arrays that can be resized. Like arrays, vectors use contiguous storage locations for their elements, which means that their elements can also be accessed using offsets on regular pointers to their elements and are as efficient as arrays. But unlike arrays, their size can change dynamically, ...
