Input Values(You must enter all user input value here, that you want to use during runtime)



To Run C++ Program 1. #include<iostream.h> change to #include<iostream> 2. #include<math.h> change to #include<cmath>; 3. #include<string.h> change to #include<cstring>; 4. Add line using namespace std; These all(1 to 4) will be done automatically..., So don't worry.
