ABSOLUTE C++ (4TH EDITION) PART 17 PPT

1. Write a program that converts from 24-hour notation to 12-hour notation. For example, it should convert 14:25 to 2:25 P.M. The input is given as two integers. There should be at least three functions: one for input, one to do the conversion, and one for output. Record the A.M./P.M. information as[r]

In Display 6.2 we have rewritten the class for a certificate of deposit from Display 6.1. This new ver-sion has a member variable of the structure type Date that holds the date of maturity. We have also replaced the single balance member variable with two new member variables giving the initial bala[r]

named global constant. If we had written the global constant MAX_NUMBER_SCORES into the body of the function fillArray, we would not have been able to reuse the function in the pro-gram in Display 5.6. Even if we used fillArray in only one program, it can still be a good idea to make the declared ar[r]

THINKING OBJECTSIf you have not programmed with classes before, it can take a little while to get the feel of pro-gramming with them. When you program with classes, data rather than algorithms takes center stage. It is not that there are no algorithms. However, the algorithms are made to fit the dat[r]

15. a. Only one. The compiler warns if you have no public: members in a class (or struct, for that matter).b. None, but we normally expect to find at least one private: section in a class.16. The member variables should all be private. The member functions that are part of the interface should be pub[r]

Variables, Expressions, and Assignment Statements 21an addition, it is usually best to include the parentheses, even if the intended order ofoperations is the one dictated by the precedence rules. The parentheses make theexpression easier to read and less prone to programmer error. A complete set of[r]
