Sprayed so much, there must be great God saw that I too young too simple, their ability to spray C + + Primer, which can only be counted as an introductory book, Advanced and High-level and other such as xxx xxx and xxx, I just want to say that people want to poison people please roll away point, What

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

the function that declares it and in any function nested within the body of the function. So in a function body, no matter where the variable is declared or even before it is declared, it can be used (without prompting for an error), but only after it has been declared and assigned, can it use the value assigned to it correctly. Therefore, in general, a good habit is to put the local variables to be declared in the function body at the top of the function body. var scope= "Global"; function f (

the output-related information, for example, the field width, decimal places, counting method used for real data, and the address of the streambuf object used to process the buffer zone. The following statement is to put the characters in the string into the cout Management Buffer through the streambuf object. Today's status is not very good (probably because I want to go back to school today, and my heart is still inactive), so I wrote so much. After reading c

before or after the original element. (Note: Adding and minus N does not make the new pointer out of bounds.) Allows you to point to the next position of the last element of the array, that is, the super-tail, but not to dereference the tail, but only as a sentinel, acting like the end () iterator of the vector.9. Subtract two pointers to the elements in the same array (including the super-tail pointer): Gets the spacing between the two pointers, the type is ptrdiff_t (signed). Two pointers add

C ++ Primer Plus Reading Notes, This article aims to record some key knowledge points in the fifth edition of C ++ Primer Plus for future reference. This article will be updated constantly ...... Chapter I. III 1. unsigned integers cannot store negative values. The advantage

"C Primer Plus" is really a great book, but the letter is not as good as the book, the author Stephen Prata may also hope that his readers can find a little bit of his inadvertently appear in the small mistake it! in the fifth edition of the book, chapter 17, "Advanced Data Representation", listing 17.2 shows the following code:#include #include #include #define

Learning Summary1. The C language was developed by Dennis Ritchie of Bell Labs in 1972 when designing UNIX operating systems with Ken Thompson. 's design is derived from Ken Thompson's B language. Anyway, it is the product of 70th century, the existence is reasonable.2, because Unixlinux are based on C language development, so, C ubiquitous: games, operating systems, computer language, embedded, applications ...3, c implementation sequence: source (. c) → compiler → target code (. obj) → linker

the built-in logical and, logical, or comma operators are not guaranteed to be evaluated. Class members and non-member overloaded operatorsOverloaded unary operator If there is no (explicit) parameter as a member function, there is a formal parameter as a non-member function. Similarly, the overloaded two-tuple operator has a formal parameter when defined as a member, and two parameters when defined as a non-member function. The principle of setting an operator to a class member or a no

cannot be dereferenced or self-increment.(4), other operations of the iteratorAnother pair of executable iterators is the comparison: with = = or! = operator to compare two iterators, if the two iterator objects point to the same element, they are equal, otherwise they are not equal.5.1 Standard library Bitset typeSome programs handle an ordered set of bits, each of which may contain a value of 0 (off) or 1 (on). A bit is a concise way to hold yes/no information (sometimes called a flag) for a

comparing their element pairs.3.5 container-sized operationsAll container types provide four container-size-related operations. The size of the sequential container operation C.size () Returns the number of elements in container C. return type is C::size_type C.max_size () Returns the maximum number of elements that container C can hold, with a return type of C::size_type C.empty () Returns a Boolean value that marks whether

The second string is added behind the first string, and then the first string is returned. While the first string changes, the second string is unchanged.3) Strncat () function: accepts t
