C++2.0 New Features

Overview

C++2.0 is a shorthand for "Modern C++", including C++11/14/17/20.

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: '>>' should be '> >' within a nested template argument list, compiles normally from C++11 onwards

• 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 yourself, the compiler won't provide a default ctor. If you force add =default, you can regain and use the 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 Structure and Classification

  • (1) Sequential containers include: array (new in C++2.0), vector, deque, list, forward_list (new in C++2.0)
  • (2) Associative containers include: set/multiset, map/multimap
  • (3) Unordered containers (new in C++2.0, replacing hash_xxx with unordered_xxx) include: unordered_map/unordered_multimap, unordered_set/unordered_multiset

• Hash Function

• tuple

Input:

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

Output:

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