First, object-oriented programming1.1 What is object-oriented programmingThe core of process-oriented program design idea is the decomposition of function. Separating the data structure and process, focusing on the process, the designer first

The STL iterator is shaped as a pointer, so the iterator acts like a t* pointer, declaring that the iterator is const just as if the declaration pointer is const (declaring a t* const pointer), indicating that the iterator must not perform something

Design patterns are the embodiment of design principles. In the world, the legend is martial arts cheats, summed up some of the fixed routines, programming the "Sunflower Treasure Book." personal opinion, the design principle is followed in the

※ Method of calling functionEBP: The extended base point pointer Register (extended base pointer) contains a pointer to the bottom of the top stack frame of the system stack. ESP: (Extended stack pointer) is a pointer register that is used to point

Introduction to Macros 1. C language before compiling the source program, will be a number of special pre-processing instructions (such as the previous use of the # include file contains instructions), a new source program (this process is called

1. Constant is the amount of the program can not be changed during operation; A variable represents a storage area where the stored content is the value of the variable, and the value of the variable can be changed during program operation(a

1, the role of GetChar ()The GetChar () function is to read data from a buffer into a character, the first time the data is read GetChar () will wait for the user to type enter and start reading from the buffer, if the buffer data is greater than 1

The following is a reference to some information on the Internet and verified by the program.Note that the following conditions are the result of the GCC and g++ compilers, which are different with the VS compiler.Here are some differences between

1.const is used to modify ordinary variables, indicating constants, not recommended modifications, to a certain extent do not allow the modification (in fact, can be modified)Pointer constant: The pointer (the value of the variable pointed to)

1 Reada set of integers into a vector. Print the sum of each pair of adjacent elements. Change your program so it prints the sum of the first and last elements,followed by the sum of the second and second- To-last, and so on. Vector ivect;int

Use the keyword abstract in C # to define abstract classes and abstract methods.Classes that cannot be initialized are called abstract classes, and they provide only partial implementations, but another class can inherit it and create themThe

1. String Manipulation System,system.text namespacesString is a reference type, but as a parameter is a value pass, it is stored in a string constant pool, the modification of the string is actually a new string to copyStringBuilder is the operation

In the original: Windows uses C to implement socket communicationOriginally thought C is a cross-platform, so, C in Windows and Linux under the program should be similar to Java, nothing to change, today only dawned, their class library is not the

The previous two blogs about C # class fields and the definition of class methods, this blog mainly talk about C # control structure, and VB similar, using C # and VB to learn this part of the method.First, C # control structureSecond, VB control

The application of pointers in C language algorithmThe first thing to say is sortThe sorting is basically divided into 5 kindsInsert Sort, select sort, swap sort, merge sort, assign sortFirst, 7, 8, bubble sort.#include #include using namespace

1. Block base block declaration a bit like a C-language function pointerC code  int func (int); Int (*pfunc) (int); int func (int p) { printf ("%d", p); return p; } where Func is a function, Pfunc
