Download file to see previous pages Recursion is an alternative to REPEAT command. In general, Recursion is delineating as the process under which a function is defined in such a way that the function being defined is applied within its own definition. The term can be explained by taking a very simple example. Suppose, when the surfaces of two mirrors are placed parallel with each other the nested images that occur are a form of recursion. The great advantage of recursion is that an infinite set of possible sentences, designs or other data can be defined, parsed or produced by a finite computer program. Logo allows the recursion where a procedure calls itself.
The secret of recursive programming is the same as a secret of problem solving in general that is to reduce a big problem to a smaller problem. Now to make the above program more general and flexible, we can use recursive pattern in the following way.
In the above example, we use the variable word instead of word "hello" and a general relationship is defined that will transform hello into hell. That relationship is established using the keyword butlast.
The above procedure becomes more meaningful using the stop rule. To implement stop rule user must answer, "What's the smallest case we want the program to handle" The answer is that for a single-letter word the downup should just print the word once. In other words, for a single-letter word, downup should carry out its first instruction and then stop. So the stop rule goes after that first instruction, and it stops if the input has only one letter:
to downup :word
print :word
if equalp count :word 1 [stop]
downup butlast :word
print :word
Another application of recursion is to draw square spiral. The following is the code to draw square spiral.
IF :L > 150 [STOP]
FD :L RT 90
SQSPI :L + 5
Suppose we give a command SQSPL 100
That means he should write 100 on a piece of paper and put it in his :L pocket.
IF (:L > 150) [STOP]
This is "the stop condition". The turtle looks in the front of his :L pocket and sees 150. He asks himself if 100 >150. If it is, then he will STOP. It is not, so he carries on.
Now "the action" is performed. First FD :L, so the turtle walks FD 100. Then RT 90. Now he has drawn this:
And then "the call":
SQSPI :L + 5
How can we tell the turtle to do SPIRAL again before he has finished with the first The turtle does not care. He just says I will finish the first SPIRAL later. He knows that the latest paper he put in his :L pocket is the only thing he needs to keep track of now. He saves the rest for later.
: L + 5 is 100+5. That is 105. Therefore, the turtle now puts a paper with 105 in front of the other paper in his pocket. The next thing he sees is this:
IF (:L >150) [STOP]
This is "the stop condition" again. He looks at the paper he just put in his :L pocket. Its 105, so it is smaller than 150. Therefore he does not stop.
Then there's "the action". He sees FD :L. So he walks FD 105. Then RT 90. Now he has drawn this:
Then there's "the call" again:
SQSPI :L + 5
He says: I will finish this later. Now I must draw SPIRAL 110. He writes 110 on a paper and puts it in front of the o ...Download file to see next pagesRead More

Procedural programming languages and object oriented programming language

...Procedural programming languages and object oriented programming language Introduction: Object oriented languages and procedural programming languages are basically two different paradigms based on two different thought processes. Both paradigms offer different approaches to model system solutions. Procedural programming is simply an approach to programming and the languages that support this methodology are called procedural programming languages, as is the case with object oriented programming languages. However it should be noted that it is possible to write an object oriented code using a procedural language like turbo C, similarly it is also possible to write a procedural code using an object oriented programming language like C#. 2...

What makes bad logo

...What makes a bad logo? A logo is a symbol of advertisement as it is used to project the image of a particular brand. However, a logo could either be good or bad as a logo can make a good brand look bad. It is important to look at the things that make a bad logo. A logo that does not appeal to its audience is a bad logo. Thus, in designing a logo, the type of audience that the logo is meant for must be put into consideration (Chase et al. 2008). A logo that does not tell a story in the simplest form, but makes it more complicated is a bad logo (Chase et al. 2008). A logo that starts with a bad font and ignoring the weight and letter spacing is a bad logo (Chase et al. 2008). The use of computer tricks in designing a logo could also make...

An Analysis of the Differences in Brain Processes of Males and Females during Language Tasks

Such is the case with the development of cognitive functions and language skills. While the brain may have complexities that we simply haven’t even yet scratched the surface of, seemingly every day there are advancements in our knowledge of brain functions.

MRI’s and various cognitive function tests have shown that males and females use different parts of their brains while performing the exact same language tasks; the biological basis for this is due to the organizing effects of testosterone and estrogen. Females have long been known to be slightly ahead of males as far as language skills at younger ages, but this could also be attributed to the fact that overall females develop earlier than males and reach...

Teaching Language and Communication Skills

“Language occurs through an interaction among genes (which hold innate tendencies to communicate and be sociable), environment, and the child’s own thinking abilities” (Genishi, 2006). But just how does this happen? How do children learn to use sounds to communicate and then to place those sounds in the correct order to make themselves understood? While some of this behavior can be attributed to the imitation of the caregivers, there remain aspects to the development of language and communication that cannot be so easily explained. To provide a more complete understanding of how language and communication develop in the young child, it is necessary to understand not only the primary terms that are applied, but al...

Childhood Language Acquisition

The study of language is inherently victim to scientific frustration because of our inability to create language. Indeed, the subject of study is confined to those languages already ensconced into linguistic communities. Children’s acquisition of language is an equally troublesome area of research insofar as children are not subject to the researcher’s manipulation like any other variable Moreover, unlike the ideal variable in the study, a child’s linguistic development does not occur in a vacuum: it coincides temporally with not only physical/motor growth, but also cognitive, perceptual, and social development. In spite of these methodological problems with studying the nature of the language-acquisition process...

Explorations in Language and Meaning

...Although dictionaries exist that claim to offer clear and concise definitions of words, for linguistics the issue involves philosophical concerns: How is objective meaning determined for language? What methods are used to determine the difference between one word and another? Is it possible to say words spelled similarly have different meanings? This essay examines these questions by analyzing the linguistic concepts of Referential Theory, Image Theory, Polysemes, and Homonymys. 1. THEORIES OF MEANING Referential Theory Referential Theory refers to a method of determining linguistic meaning. In this theory, word meaning is determined by everything that can be physically referenced to the word. These connecting words are referred...
