Optimize C++ Code with Member Initializers
Calling constructors for the data members of the object of a class results in an overhead process which calls the constructor in the main function. You can reduce this overhead by using member initializers in classes. For example:

Class A
{public:
A(int i,int w){
a=i;b=w;}
private:
int a,b;};
//INSTEAD WE CAN USE MEMBER INTIALISERS EXAMPLE FOLLOWS
Class A
{public:
A(int i,int w):a(i),a(w)
{//empty body of constructor }
private:
int a,b;};
The latter code is better optimized and more efficient.
