Problem solving has been described as the process of finding certain information that is not known, from a set of information that is known. In other words, problem solving is not an end result but rather a process. The end result is only worthwhile if the process is followed.

• Thoroughly understand the problem
• Break the problem down into its component parts
• Arrange the solution in a clear and systematic way
• Translate the solution into a computer language

It would be unfair to ask anyone to solve problems without effective tools to help along the way. The nature of programming requires programmers to first solve the problem at hand, then create an ordered set of instructions that will teach the computer how to solve the problem. There are a variety of problem solving models that assist the programmer in the problem solving stage.

In this Lecture we will

• look at flowcharting a diagram, using symbols and arrows, which describes the solution to a computer problem in a step by step manner.

To this point, all the data that we have used when executing our programs has been entered from the keyboard. Similarly, all the output that has been produced from our programs has been to the screen. We must realize that not all input and output occurs this way, in fact, the majority of input for a computer program comes from data files that are stored on a disk or hard drive. When we create a document in a word processor, we see it on the screen; however, if we want to store that information, so that we can use or edit it at a later date, we must output the data to some secure storage medium. In the next few lessons, we will see how data storage and retrieval works.

Data produced from a program as the result of successful processing, can be output to a file for storage, rather than simply to the screen. Once stored, the data can be accessed for further processing, used as input for programs, searched for specific information, sorted, updated ... you get the idea!

Everyone using a computer deals with files. When you turn on your computer, the computer loads files. When you start a piece of software, the computer loads files. When you type solutions to the questions in this unit and save them (hopefully), the computer is saving or writing to a file. We use files to store information that is not being used by the computer at the present time.

Can you think of any useful program that doesn't use files? Files are a very important concept to understand, because any really useful piece of software uses files. Even your video games store your high scores.

Note: The structure definition looks alot like the field definitions for a class. Right after the structure def we create an array of CListOfCars called Car

Notice below how we are using an array to refer to each part of the car structure and how the array is a mixture of text (strings) and numbers. You can't do that with a regular array.

string p = Application.StartupPath;
Car[1].Make = "Honda";
Car[1].Model = "Civic";
Car[1].CarYear = 1998;
Car[1].Doors = 4;
