Always initialize a variable.

 int var;  //NOT INITIALIZED, BAD
 if (cond)      // some non-trivial condition
 	Set(&var);
 else if (cond2 || !cond3) {
 	var = Set2(3.14);
 }
 // use var

Always use {} initializer syntax

• applicable

   int arr[] = {1,2,3}
   std::map<std::string, int> mymap {{"scott", 1997}}; 
  const float* pData= new const float[3]{1.1,2.2,3.3};	//TODO
  

class MyClass{ public: int x; double y; }; Class myClass{2011,3.14}; MyClass myClass1= {2011,3.14}; ```

• avoid narrowing??
• Keep in mind that {} initializer and {} will give you std::initializer_list in c++14, not inC++17

Always use a smart pointer to hold a raw pointer

• it's as efficient as a raw pointer
• manages resources for you
