First, chapter review:Cycle. A syntactic form that executes a sentence repeatedly.1. Basic syntax:for (initial condition; cyclic condition; change of State){Loop body}The four elements of the loop.The execution process of the loop. Initial conditions--cyclic condition--cyclic body--state change--Cyclic condition--。。。。。Case: 1. Print 10 hello. 2. Displays 1-100 of the number (all, odd, even). 3. Display ASCII code.2. Looping the nesting.for (...; ... ;

The second chapter learns the R function:1 sum calculation and sum (x,na.rm=true) calculated in Vector x, which excludes NA elements2 Median calculates the median to return the number of the middle of a sample data median (x,na.rm=true)3 Max COMPUTE Max Max (x,na.rm=true)4 min Compute min min (x,na.rm=true)5 c () Connect data connection data to form a vector. C (a)6 Cbind data cbind with column variables (x

Chapter III types, values, and variablesContent EssentialsI. Data type1. Types of values that can be represented and manipulated in a programming language are called data typesThe 2.JS data types fall into two categories:Primitive types: Numbers, strings, and Boolean valuesObject typeThere are two special primitive values in 3.JS: null (NULL) and undefined (undefined)4. Object: is a collection of attributes (property), each of which consists of a name

We recommend that you first look at the preface: http://www.cnblogs.com/tanky_woo/archive/2011/04/09/2010263.html This chapter has a lot of content, so I will write it in four articles. This article is about some basic concepts and choices. The two articles in the middle are insert and delete, and the last one is a summary. The previous chapter summarizes BST (h

12th Chapter Dynamic Memory1. Apply for and use shared_ptr. P4002. shared_ptr count. P402assigning, copying, passing a smart pointer to a function, or returning a smart pointer to a function will increase the current count of smart pointers.3. Examples of sharing data between different objects using smart pointers.4. Use new to dynamically request memory. P407By default, the memory objects that are requested by new are initialized by default.

derived class defines a function void P (); void P () is also a virtual function because the function has the same name as the virtual function of the base class and is called in the same form . It is strongly recommended that you add the virtual keyword before the derived class void P ().If the function in the derived class is void P (int x=1); In this case, the P function is not a virtual function and masks the virtual functions of the base class called P ().We analyze each of the 4 calls in

class object is needed .In Class A, the object of Class A is replaced with 100 and CIN respectively.only one-step class type conversions are allowed ! However, built-in type conversions support multiple steps. That is, the above statement can be written as a1=a1+100.3; Turn 100.3 to Int ( built-in conversion ), and then convert int to Class A object ( class type conversion ).The code above wants to turn the object into B , and then turn it into a object. An error will occur .Suppressing impl

4th Chapter Expressions1. When Decltype acts on an Lvalue object, it returns the reference type of the object. When acting on an Rvalue object, the type of the object is returned.2. Order of Evaluation.In C + + only | |?: and , 4 operators are evaluated first left and right.3. The unary plus sign operator acts on the value:the type that will raise the current value , like Short become int type4. The results of m% (-N) and (-M)%n with (-m)% (-N) are:

authenticity of the loop condition.④ the loop body first, then the cycle condition is judged.(3) The same point: the expression can be any legal expression, the loop body statement can only be a statement, the loop body statement must contain can eventually change the loop condition of the authenticity of the operation.(4) Different points: Whlie, for first judge the condition, the condition satisfies after enters the circulationDo-whle the loop body first, then the cycle condition is judged.Ex

The main content of this chapter is software testingValidation and ConfirmationBugs in Software1. The software does not meet the function specified in the product specification; 2. The software has appeared the error that the product specification indicated does not appear; 3. The software function is beyond the scope specified in the product specification; 4. The software does not meet the product specification, although it does not indicate the goal

MountainMemory system performance is not a number can be described. Each computer has the only memory mountain that indicates the capabilities of his memory system. It is a local mountain of time and space, and the elevation of this mountain can vary more than one order of magnitude. If the program runs on a mountain rather than a trough.Objective: To make use of time locality to remove frequently used words from L1 and to use spatial locality to make as many words as possible from a L1 cache l
