The program in Display 7.6 is the outline of a scenario that has one queue of clientswaiting for service and two servers to service this single queue. You can come up with anumber of system programming scenarios to flesh this out to a realistic example. For asimple minded model just to learn the conc[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]

int, one for the dollars and one for the cents. This illustrates the fact that the internal repre-sentation of the data need not be simply a member variable for each conceptual piece of data. It may seem that the balance should be represented as a value of type double, rather than two int values. Ho[r]

■ DECLARING AND REFERENCING ARRAYS In C++, an array consisting of five variables of type int can be declared as follows: int score[5]; 5.1 ARRAY TRANG 2 Introduction to Arrays 173 This d[r]

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]

Whenever you give two or more definitions to the same function name, the various function definitions must have different specifications for their arguments; that is, any two function de[r]

You might be tempted to think the function definition could be simplified to the following: To see that this alternative definition cannot work, consider what would happen with this defi[r]

All the programmer should need to know is the function declaration and the accompanying comment that describes the[r]

int that gives the number of array posi-tions used. When a letter is deleted, the remaining letters are moved forward to fill in the gap. This will create empty positions at the end of the array so that less of the array is used. Since the formal parameter is a partially filled array, a second forma[r]

For example, the void function initializeScreen, defined below, simply sends a newline command to the screen: void initializeScreen { cout number; 12 cout > totalWeight; 14 iceCreamDiv[r]

The following generates a pseudorandom floating-point value between 0.0 and 1.0: rand /static_castRAND_MAX The type cast is made so that we get floating-point division rather than intege[r]

In addition to simulating games of chance, random numbergenerators can be used to simulate things that st[r]
