real application program would be much more elaborate, but this shows all the essentials of the sequential search algorithm. The sequential search is the most straightforward searching algorithm you could imagine: The program looks at the array elements in order, first to last, to see if the target[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]

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]

functions.■ A function should be defined so that it can be used as a black box. The programmer who uses the function should not need to know any details about how the function is coded. All the programmer should need to know is the function declaration and the accompanying comment that describes the[r]

That in turn is equivalent to 0 > 60, because 60 is the value of limit, and that evaluates to false. Thus, the above logical expression evaluates to false, when you want it to evaluate to true.There are two ways to correct this problem. One way is to use the ! operator correctly. When using t[r]

As in most programming languages, C++ handles flow of control with branch-ing and looping statements. C++ branching and looping statements are similarto branching and looping statements in other languages. They are the same asin the C language and very similar to what they are in the Java prog[r]

On the other hand, if the value of i is 0, then this call is equivalent to the following: myFunctiona[0]; The indexed expression is evaluated in order to determine exactly which indexed [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]
