Consider the following class definition where a circle is represented just by its radius: class Circle{   private:      double radius;   public:      double scaled_area(double factor) const;}; What does const mean here?

The following function definition requires two  input parameters: str1 and str2. Choose the best and correct parameter definition to fill in the blank in the code below. void do_something(______________________________) {   if (str1.length() > 5 && str2.length() > 10) {      if (str1[0] == ‘a’) {         str1.replace(1, 2, str2.substr(3, 5));      }      else {         str1[0] = ‘z’;      }   }}

Using correct C++ syntax, write the definition for a class called Person which ONLY contains four public class attributes: name (string), age (integer), height (integer), and bank balance (double). Do not define any member functions.

Consider this declaration and initialization: string str = “cse1222” ; What is the evaluation of the expression: str.substr(1, 3)?

What is the LAST value that is output to the screen (by the cout statement) at the end of execution of the following code? Trace the code line-by-line. Use the Proctorio whiteboard as scratch space, if needed. int val(2);while (val > 0) {  cout
