2.C++2.0 New Features

2.0 Overview

C++2.0 is an Abbreviation, meaning「modern C++」，including C++11/14/17/20.

2.1 C++11 New Features

• Variadic Templates

• Spaces in Template Expressions

  vector<list<int> > //ok in each C++ version
  vector<list<int>> // before c++ 11 error error: ‘>>’ should be ‘> >’ within a nested template argument list,version beyond c++ 11 could   compile successfully

• nullptr and nullptr_t

• Automatic Type Deduction with auto

• Uniform Initialization

• initializer_list

• explicit for ctors taking more than one argument

• range-based for statement

  for(decl:col) {
      statement
  }

• =default,=delete

  If you define a ctor by yourself, compiler won't compile the default ctor. If you add =default, you could recatch and use default ctor.

• Alias(化名)Template(template typedef)

  • alias.cpp
  • template_template.cpp

• template template parameter

• type alias

• noexcept

• override

• final

• decltype

• lambda

• Rvalue reference

• move aware class

• Container-Struct And Classify

  • (1) Serial containers include：array(C++2.0 Newly Introduced),vector,deque,list,forward_list(C++2.0 Newly Introduced)
  • (2) Associated containers include：set/multiset,map/multimap
  • (3) Unordered container(C++2.0 Newly Introduced,replace hash_xxx to unordered_xxx) include：unordered_map/unordered_multimap,unordered_set/unordered_multiset

• Hash Function

• tuple

7.Tools

7.1 Container shortcut output tool

Modified the code, Click here for the code

Input：

map<int, int> mp{
            {1, 1},
            {2, 4},
            {3, 9}};
    cout << mp << endl;

Output：

{ 1 => 1, 2 => 4, 3 => 9 }
