Writing a computer programs to write computer programs You only need to learn five things to write computer programs: Variables, which are named boxes to put information in Operators, which do things to pieces of information, like add them together, subtract them, multiply them and so-on Conditionals, which are rules for making decisions, expressed in "if When a programming language gives you the above five things, we give it a name in honor of the man who figured out these basics: This also applies to all of the books and blog postings about computer programming, because they are either teaching how to use a set of function calls assembled together into a library, or the most advisable strategy for making your own library of function calls, or how to organize a team of programmers who are making programs and libraries of function calls.

Information and variables Information is always numbers to a computer, but often words to us. The metaphor that programmers are taught is of a cardboard box with a label on it, and the label is the variable.

The cardboard box is misleading, because in the computer's memory it's like a single massive cardboard box, and on the edges someone has used a marker to draw dividing lines.

A variable simply applies a temporary label to one of those marked divisions, along with a rule for figuring out how many divisions that name covers. Strings Words, sentences, paragraphs and books are numbers linked together like sausage links into strings.

To a computer they're opaque in meaning and processed like a sausage machine chopping them into segments according to one rule or another. I could say, "break up this string by its spaces" and get a list of all the words in a sentence, or I could say "break it up by hyphens" and get the three numbers in a Social Security number.

For example, if the input to such a program was "" then it would produce three discrete values like this: A bug is the result of not preparing the computer for what it would be told.

Just like telling your pregnant wife that you're sterile, you may have a result that's catastrophic for both of you.

Bugs are dealt with by regulating the input and broadening the scope of what the program can cope with. Someone called Trevor Lewis may be a schoolboy in and a musician in because they change. Implied are all the rules for figuring out where the book ends and the other things stored in memory begin.

Operators Addition, subtraction, multiplication and division are the basic operators as we know them. When you sit down to program a computer, you use a language that classifies variables by type, which helps it figure out how to apply those operators.

In boldcase are operators: If I put words inbetween quotes, I'm giving you a string. But if I use a name without quotes, I'm talking about the name I gave to a variable.According to initiativeblog.com, 90 percent of parents in the U.S. want their children to learn computer science—it will be crucial for many jobs in the near future—but only 40 percent of schools teach initiativeblog.coms claim that it is mainly the more affluent schools that offer computer science courses, thus denying those who attend poorer schools the chance to learn necessary skills.
