string operator

Once a C + + expert said: see a C + + programmer is hard enough, let him write an assignment overload function can be seen! In my opinion, this is not an exaggeration. Because it really needs a solid foundation to write the operator= function well,

String In My Learning life in C + + I found that the string class is very powerful, so we have to simulate it, and in the interview, simulate a string class is also a regular exam, but because of outside constraints we are not possible to simulate

Initialization Function prototypes Function String () To create an empty string String(const string& str) Initializes another string object with one string object

The string class in C + + can implement a series of operations on a string object, as shown in the following diagram as part of a string that is intercepted from the Cplusplus: Next I'll simply simulate a few function implementations First,

Compiling environment (vc6.0)C++ Supports two initialization modes: Direct initialization and replication initialization. Direct initialization directly calls the constructors that match the real parameters, and the copy constructor is always called

Bjarne stroustrup, the C ++ designer, has made great efforts to make user-defined types work in the same way as fixed types. This is why you can overload operators, write type conversion functions (see article 5), control assignment and copy

Category 4 Design of the 4.1 category Class is the basis of object-oriented design. A good class should have a single responsibility, clear interfaces, few but complete interfaces, low coupling between classes, and high internal class And

Java BasicsWe learn the Java Foundation to put this knowledge to remember the method of only one is to knock the code, in this period of learning we have to learn the knowledge of the convergence, the following is the two basic projects I wrote:The

C + + dynamic memory management is very important, improper operation can easily cause memory leaks,Below I have detailed some memory management where this attention is made, including the implementation of reference countingDeep copy Shallow

The preceding two sections describe the Rvalue reference and its effect. The use of rvalue references is described below through the writing of a string class. With respect to c++98, the movement constructor and the move assignment operator are the
