But rather than quit out of the loop, you may want to simply ignore the current piece of bad data and then continue reading more data. The ForLoop4 example that follows shows a slightly modified version of the previous example, in the “Breaking” section. When the loop gets to 5, it doesn’t execute the second cout line. But rather than break out of the loop,
your project manageable. Also, with multiple source code files, you can have several people working on a single project, each working on a different source code file at the same time. The goal, of course, is to make sure that your coworkers work on the harder parts that are more grueling and no fun while you get all the credit. The key to multiple source files is knowing where to break the source code into pieces. Like anything else, if you break the source code in the wrong place, it will, well,
the ptr variable. Then you start doing your magic on it. Okay, so it’s not all that magical, but you save a 10 in the thing that ptr points to. And then you print the value stored in the thing that ptr points to. But what exactly is the thing that ptr points to, and why does it fancy itself so important as to justify italics? It’s the memory that was allocated by the new operator. Think of it as a variable out there somewhere. But unlike regular variables, this variable doesn’t have a name. And
we say class. This thing in my hand belongs to the pen class. Now if we point to the thing parked out in the driveway, and ask you, “What class does that belong to?,” you will answer, “class Car.” Of course, you could be more specific. You may say that the thing belongs to class 1999 Ford Taurus. When we show you the pen, we are asking you what class this object belongs to. If we then pick up another pen, we’re showing you another example of the same class. One class, several examples. If we
