class Alpha { public: char data[10000]; Alpha(); ~Alpha(); }; class Beta { public: Beta() { n = 0; } void FillData(Alpha a); private: int n; }; How do you make the above sample code more efficient? a) If possible, make the constructor for Beta private to reduce the overhead of public constructors. b) Change the return type in FillData to int to negate the implicit return conversion from "int" to "void". c) Make the destructor for Alpha virtual. d) Make the constructor for Alpha virtual. e) Pass a const reference to Alpha in FillData

Am studying basic c++ programming, have been given the following assignment. Design a linear program to calculate the maximum stress a material can withstand given a force and a diameter of a circle. To find the required area pi should be defined. Have most of the program sorted out but am at a loss as to how to show the calculations required. Can anyone help?
