Static semantics[ edit ] The static semantics defines restrictions on the structure of valid texts that are hard or impossible to express in standard syntactic formalisms. Examples include checking that every identifier is declared before it is used in languages that require such declarations or that the labels on the arms of a case statement are distinct.
Teaching your kids how to write computer programs by Marshall Brain Quick Intro - If you are looking for a quick and easy way to teach your kid a real programming language, without downloading anything or buying anything, try these Python tutorials.
Your kid will be writing and modifying code in just a few minutes. Marshall Brain's quick and easy Python tutorials Let's say that you have children, and you would like to help them learn computer programming at a youngish age.
As the father of four kids, I have tried to approach it from several different angles. What I would like to do here is collect some ideas for parents who are looking for different options. Let's start with a something important: Every kid is different.
Some kids are reading and writing fluently years ahead of other kids. For them, learning to program is probably easier. Some kids have the basic analytical skills a lot earlier than others Here's a story about a 9-year-old writing full-blown iPhone apps. You try to expose your kids to programming and it may or may not "take" the first time, simply because of these differences.
So you wait a few months and try again, or you might try a different approach. Understand that, the first time you try to introduce your kids to programming, your kids might not "get it" at all. The second thing to realize is that real analytical skills often don't start appearing until age 11 or 12 or 13 in many kids, so expecting huge breakthroughs prior to that may be unrealistic.
That being said, there are lots of fun things you can try as early as five or six Games Let's start with a few games. Here are three games that my kids have particularly enjoyed.
They teach basic problem solving ideas in different ways: Magic Pen wait a few seconds to see the word "play", then click the word "Play" Fantastic Contraption Auditorium Drag the circle-with-arrow-in-it around.
Enlarge or shrink the outer circle by dragging. Try to aim the stream at the bars. Once the bars fill, click anywhere to go to next level If you look around on the web you can find lots of "problem solving" games like these three.
Then there is this game, which actually does a very good job of teaching simple programming skills: It will engage kids for a couple of hours, starting at age 7 or 8. Some of the puzzles in LightBot are too hard for kids.
There are walkthroughs on YouTube that help. Prefer games on a tablet or phone? See also this list. You can find out more about it on a page like this: Python for Kids Logo is pretty limited.
What if you want to teach your kids a "real" programming language? Python may be a good option to try because it is now fairly ubiquitous and it is easy to get started.Google’s researchers have taught machine-learning software to build machine-learning software, in a project dubbed AutoML.
Citation Machine™ helps students and professionals properly credit the information that they use. Cite sources in APA, MLA, Chicago, Turabian, and Harvard for free. A machine language program is a sequence of machine language instructions in main memory.
A machine instruction consists of one or more bytes (in this example, only one). The processor runs a program one machine instruction at a time. All the little machine operations add up to something useful. Appendix: Power As an illustration of what I mean about the relative power of programming languages, consider the following problem.
We want to write a function that generates accumulators-- a function that takes a number n, and returns a function that takes another number i and returns n incremented by i.
Example of Machine Language. Say that a light bulb is controlled by a processor running a program in main memory. The controller can turn the light bulb fully on and fully off, can brighten or dim the bulb (but not beyond fully on or off.) Or, write a program so that the bulb gradually brightens and dims repeatedly.

If you've asked someone the secret to writing efficient, well-written software, the answer that you've probably gotten is learn assembly language programming. By learning assembly language programming.
