blink chapter 6 summary

11th Chapter related Containers1. A simple example of using map:The result of the operation is:2. Initialize the map and set:3. The difference between set and Multiset:4. When using map and set, the element type must be strictly weak (that is, the comparison is defined ), and if the element type does not have a defined 5. Pair type: Pair is a template that is used to generate a specific type. The default constructor for the pair initializes the v

it will be an error ( you can try it yourself to see what the situation is ).18. Assignment operators achieve copy assignment and move assignment two functions P478If the parameter of the assignment operator is a call to a value , the initial taxiing parameter with the argument needs to call the copy constructor ( The argument is an lvalue ) or move the constructor ( the argument is the right value ). Then the equivalent copy assignment and move assignment can be implemented in the following wa

parameter problem; 3. "Wild Pointer" question; 4. Programming recommendations. Exception Handling issuesException handling mechanisms are useful, but are also prone to misuse and cause code clutter. In the process of using exception handling, it must be very clear that there is no exception thrown and after the exception of the program execution process, grasp the exception handling of the jump and nesting mechanism, and pay attention to the exception handling of memory problems. Performance Is

Summary of the first phase of fusioncharts V3 localization plan (Chapter 1 completed in Chinese) The index is as follows: Fusioncharts V3 is a set of very good flash Chart display controls. Currently, we have chosen it as a front-end display tool in our self-developed Bi system. Although many friends in the garden have adopted this tool, unfortunately, there is not a complete Chinese tutorial. I foun

(P307), the following is the use of insert:Use Insert The return value : Insert () returns an iterator to the first element it inserts .6. Use the Emplace operation:7. In addition to forward_list, other sequential containers support front () and back () operations, but P311 Books say they return references , But my test results are not so , where is the problem ?Let's look at another way:Description Front () and the Back () does return a reference

a const variable and that the variable must be initialized. You might say that this const is not the same? constexpr is more rigorous, the expression used to initialize the variable must be a ' constant expression ' . This means that the constexpr variable is a const variable initialized by a constant expression . As for the constant expression, we'll talk about it later, for the basic data type, the constant expression is a literal constant, a variable that constexpr the limit, and a cons

3rd chapter strings, Vectors and arrays1. How do I read a whole line of content with a string?You can use Getline (cin,s). Of course getline () can also be used as a while loop to read input judgment conditions.2. String literals and literal values of strings are addedSince the + method is left-to-right, so long as the two values are guaranteed to be added, at least one of the two sides of the + sign is a string on the line.3. String can be added not

identifiers cannot have duplicate names with keywords.2 The variable name is all lowercase (if it consists of multiple words, the first letter of the following word is capitalized)3 constant names are all uppercaseFive, key wordsSome of the specific meanings in Java are called keywords (keyword), which are used as specialized strings.Most editors mark keywords in a special way.All Java keywords are in lowercase english.VI.

Assuming that the user has the need, you can also use constructor to define the constructor that defines the parameters

segment register. When 8086CPU accesses memory, the segment register provides the segment address of the memory unit. The 8086CPU has 4 segment registers, where CS is used to store the segment address of the instruction. CS holds the segment address of the instruction, andtheIP holds the offset address of the instruction. 8086 machine, at any moment, theCPU will CS:IP pointing to the content as an instruction execution. 8086CPU working process:from CS:theIP points to the memory unit read instr
