'''Algorithm to print out the elements of an array''' Input a and n where n is the length of array a Set i to 0 While i < n Print ai Set i i + 1.
This will be the sorted list.The first element of both lists is compared. If sorting in ascending order, the smaller element among two becomes a new element of the sorted list. This procedure is repeated until both the smaller sublists are empty and the newly combined sublist covers all the elements of both the sublists.
This diagrammatic representation illustrates a solution model to a given problem. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows. A flowchart is a type of diagram that represents an algorithm, workflow or process. It starts at the Top and proceeds downwards, with each recursive turn asking the same question such as “What is required to be done to sort the array?” and having the answer as, “split the array into two, make a recursive call, and merge the results.”, until one gets to the bottom of the array-tree.Before writing an algorithm in a programming language, it is first described in a higher level language called pseudo-code.
To save time arrowheads are often only drawn when the flow lines go contrary the normal. Flow LinesNote: The default flow is left to right and top to bottom (the same way you read English). Simple Flowcharting Symbols TerminalThe rounded rectangles, or terminal points, indicate the flowchart’s starting and ending points. Return to this section in later chapters to review the advanced symbols and examples. When first reading this section, focus on the simple symbols and examples. DiscussionCommon flowcharting symbols and examples follow.
It also illustrates the sequence control structure where nothing unusual happens. This demonstrates the use of both the on-page and off-page connectors. FunctionsPseudocode: Function with no parameter passing Function clear monitorDirect the operating system to clear the monitorPseudocode: Function main calling the clear monitor function Function mainPass Out: value zero to the operating systemEnd function Function main Sequence Control StructuresThe next item is pseudocode for a simple temperature conversion program. A connector symbol that looks like a pocket on a shirt, allows you to connect to a flowchart on a different page.We will demonstrate various flowcharting items by showing the flowchart for some pseudocode. A connector symbol, which is a small circle with a letter or number inside it, allows you to connect two flowcharts on the same page. This is usually done when a flowchart does not fit on a single page, or must be divided into sections.
Input/output symbol A parallelogram used in flowcharting for input/output interactions. Flowcharting A programming design tool that uses graphical elements to visually depict the flow of logic within a function. Flow lines Lines (sometimes with arrows) that connect the various flowcharting symbols. Round up or down to the whole number.HINT: Use 32.0 when subtracting to ensure floating-point accuracy.Display the celsius with an appropriate messagePause so the user can see the answer Sequence control structure Sequence control structured continued Advanced Examples Selection Control StructuresDisplay a message indicating you can vote.Display a message indicating you can't vote.18 to 64 Display "You are in your working years."End case Case control structure Iteration (Repetition) Control StructuresWhile count zero Do While control structurePseudocode: Repeat Until count assigned fiveUntil count < one Repeat Until control structure Key Terms decision symbol A diamond used in flowcharting for asking a question and making a decision.
