ABSOLUTE C++ (4TH EDITION) PART 25 DOCX

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]

124 Function Basics■BLOCKSA variable declared inside a compound statement (that is, inside a pair of braces) islocal to the compound statement. The name of the variable can be used for somethingelse, such as the name of a different variable, outside the compound statement. A compound statement with[r]

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.

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]

tions. Since you can think of the value returned as being a random number, you canuse a random number generator to simulate random events, such as the result of throw-ing dice or flipping a coin. In addition to simulating games of chance, random numbergenerators can be used to simulate things that st[r]
