Pseudocode building blocks

Like other types of diagrams, they help visualize what is going on and thereby help understand a process, and perhaps also find less-obvious features within the process, like flaws and bottlenecks. There are different types of flowcharts: The two most common types of boxes in a flowchart are: A flowchart is described as "cross-functional" when the chart is divided into different vertical or horizontal parts, to describe the control of different organizational units.

Pseudocode building blocks

To work with data, you need to understand variables and types; to work with instructions, you need to understand control structures and subroutines. You'll spend a large part of the course becoming familiar with these concepts.

The programmer only has to worry about the name; it is the compiler's responsibility to keep track of the memory location. The programmer does need to keep in mind that the name refers to a kind of "box" in memory that can hold data, even if the programmer doesn't have to know where in memory that box is located.

What are the fundamentals building blocks of computing? - Computer Science - Science Forums

In Java and in many other programming languages, a variable has a type that indicates what sort of data it can hold. One type of variable might hold integers -- whole numbers such as 3, -7, and 0 -- while another holds floating point numbers -- numbers with decimal points such as 3. Yes, the computer does make a distinction between the integer 17 and the floating-point number There could also be types for individual characters 'A', ';', etc.

Programming languages always have commands for getting data into and out of variables and for doing computations with data. For example, the following "assignment statement," which might appear in a Java program, tells the computer to take the number stored in the variable named "principal", multiply that number by 0.

These basic commands -- for moving data from place to place and for performing computations -- are the building blocks for all programs. These building blocks are combined into complex programs using control structures and subroutines.

A program is a sequence of instructions. In the ordinary "flow of control," the computer executes the instructions in the sequence in which they appear, one after the other. However, this is obviously very limited: Control structures are special instructions that can change the flow of control.

There are two basic types of control structure: For example, it might be that if the value of the variable "principal" is greater thanthen the "interest" should be computed by multiplying the principal by 0.

A program needs some way of expressing this type of decision. In Java, it could be expressed using the following "if statement": Just remember that the computer can test a condition and decide what to do next on the basis of that test.

Loops are used when the same task has to be performed more than once. For example, if you want to print out a mailing label for each name on a mailing list, you might say, "Get the first name and address and print the label; get the second name and address and print the label; get the third name and address and print the label What you would like to say is something like "While there are more names to process, get the next name and address, and print the label.

Large programs are so complex that it would be almost impossible to write them if there were not some way to break them up into manageable "chunks. A subroutine consists of the instructions for performing some task, grouped together as a unit and given a name.

That name can then be used as a substitute for the whole set of instructions. For example, suppose that one of the tasks that your program needs to perform is to draw a house on the screen.

You can take the necessary instructions, make them into a subroutine, and give that subroutine some appropriate name -- say, "drawHouse ". Then anyplace in your program where you need to draw a house, you can do so with the single command: The advantage here is not just that you save typing.

Organizing your program into subroutines also helps you organize your thinking and your program design effort. While writing the house-drawing subroutine, you can concentrate on the problem of drawing a house without worrying for the moment about the rest of the program. And once the subroutine is written, you can forget about the details of drawing houses -- that problem is solved, since you have a subroutine to do it for you.

A subroutine becomes just like a built-in part of the language which you can use without thinking about the details of what goes on "inside" the subroutine.

Variables, types, loops, branches, and subroutines are the basis of what might be called "traditional programming.Sep 11,  · Remember that pseudocode is subjective and nonstandard.

There is no set syntax that you absolutely must use for pseudocode, but it is a common professional courtesy to use standard pseudocode structures Views: K. I would like to know how to format a pseudocode algorithm like the one shown in the picture below.

Unlimited free trial. is a plan, a set of step-by-step instructions to solve a problem. There are three basic building blocks (constructs) to use when designing algorithms.

Expressing Algorithms. Pseudocode is useful because it is a happy medium. Hopefully, these can be used as building blocks to reduce the implementation complexity of algorithms that use them, thus making more complicated algorithms worthy of consideration in practice.
