  Save every byte Description John is working on a project that has almost strict requirements on storage capacity, so John needs to compress and store something. John's first problem is that there are a lot of strings that occupy too much space, so

When using the properties or methods of other classes in the C ++ program design and design class, you must understand whether to use combination or inheritance. The combination is has a, which attributes or methods the class has, and the

Copy constructor is a special constructor with a single parameter. This parameter (commonly used for const modification) is a reference to this type. When you define a new object and initialize it with an object of the same type, the copy

14.2 input and output operatorsI/O operation interfaces provided by classes that support I/O operations should be the same as those defined in the standard library iostream for built-in types. Therefore, many classes need to overload the input and

What is centralized decision? First look at a piece of code: Class P1{Public:Int m_nVal;}; Class P2{Public:Int m_nVal;}; Int fun (const P1 & aP1, const P2 & aP2){If (aP1.m _ nVal {If (aP2.m _ nVal {Return 0;}Else if (aP2.m _ nVal = 60){Return

When I encountered this problem today, I read the relevant documents online and found the cause: Variables cannot be defined in the case of the switch, or an error will be reported. It may be that the initialization of the variable will be skipped

Q: What are '_ FILE _' and '_ LINE __'? A: '_ FILE _' and '_ LINE _' are predefined macros and part of the C/C ++ standard. during preprocessing, they are replaced respectively by a constant string holding the current file name and by a integer

The parameter format of the non-type template is the same as that of the following type.• Integer or enumeration• Pointing to an object or function• Reference an object or function• Point to a memberDeclare non-type template parameters as an array

Multi-inheritance can be seen as an extension of single inheritance. Multi-inheritance means that a derived class has multiple base classes. The relationship between the derived class and each base class can still be considered as a single

This chapter mainly introduces the basic data types in c ++ and some programming skills.The record has the following points:1. By adding a suffix, You can forcibly convert the literal value integer constant to the long or unsigned, unsigned long

I have mentioned ScopeExit before (see how to organize this code structure? Goto or do... While (0)? Http://www.bkjia.com/kf/201205/132632.html ). The usage scenario is briefly described as follows:Bool GenFile (){HANDLE hFile = CreateFile (_ T

Today, I simply flipped through Folly. Basically, the databases in it won't be useful to normal people. I thought it would be highly dependent on modules like Boost. I didn't expect it to be enough. It is not very difficult to extract features.

After graduating from college, I used to write all the algorithms in the data structure book, but it was not enough ..After I learned to use sort in STL, I never wrote too fast. In the future, I want to write these words slowly .. Step by step.#

I have mentioned a bunch of things above, that is, to give you a string consisting of digits, so that you can delete n numbers in it. The smaller the number, the better.Idea: This question is basically the same as the question on NYOJ. However, on
