Chapter 1

1. namespace

   using namespace std;

   This way can make std visible in the current action scope. Otherwise, we need to use prefix like std::, which explicitly state the namespace.
2. C++ can handle override function, but if there exists ambiguity in compiling the code, the compiler will throw an error. Such like:

   int func(double d1,int i1){}
   int func(int i2,double d2){}
   int result = func(2,3);

3. C++ sometime will do implicit conversion. Such like
   int a = 7.2, actually, 7 will be store in a.
4. C++ allow the declaration in the form
   type name {parameter p1...}; which seems like constructor. There is no equal between name and brace.
