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]

may be ended early with a continue statement. It is best to use break statements sparingly. It is best to completely avoid using continue statements, although some programmers do use them on rare occasions.ANSWERS TO SELF-TEST EXERCISES1. a. true.b. true.

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

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

In cold weather, meteorologists report an index called the wind chill factor, which takes into _ account the wind speed and the temperature.. The index provides a measure of the chilling[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]

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]

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]
