with their first letter in lowercase. The predefined identifiers, such as main, cin, cout,and so forth, must be spelled in all lowercase letters. The convention that is nowbecoming universal in object-oriented programming is to spell variable names with amix of upper- and lowercase letters (and digits)[r]

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]

sion of a while or do-while statement. If done with care, this can work out satisfactorily.An example is given in Display 2.6. Be sure to notice that in count++ <= number-OfItems, the value returned by count++ is the value of count before it is incremented. Display 2.5 Example of a do-while S[r]

Not all comment assertions can easily be translated into C++ Boolean expressions.Preconditions are more likely to translate easily than postconditions are. Thus, theassert macro is not a cure-all for debugging your functions, but it can be very useful.■STUBS AND DRIVERSEach function should be design[r]

getInput(inputNumber); C++ allows you to place the ampersand either with the type name or with theparameter name, so you will sometimes see void getInput(double &receiver); which is equivalent to void getInput(double& receiver); Display 4.2 demonstrates call-by-reference parameters.[r]

A function definition consists of a function header followed by a function body.The function header is written similar to the function declaration, except that theheader does not have a semicolon at the end.
