1.3.1 New Type

• Add three new types " long long", "char16_t" and "char32_t".
• Uniform Initialization: It will stop narrow if it’s out of range of target. but allow if the value is within the range of the target.
  int x = {5}; // When use init, prefer to use = 
  double y{5}; 
  short quar[5] = {1,2,3,4,5} 
  class c1{3,"aaa"}; //Just like class c1(3,"aaa");
• nullptr keyword, Don’t use NULL any longer. NULL is just 0.
