Question

Think about a process that you would use in your field of study, your work, or an area of interest to you. Develop an algorithm for that process and express it in pseudocode. Identify the parts that you believe could be automated on a computer I just need an example

Explanation / Answer

To begin the program code START program name To end the program code STOP The capitalized START and STOP are pseudo code words. They are in all capitals to draw attention to them. In this example the pseudo code words are also bold to draw even more attention. In practice bold letters are not required but I like them :). The sequential structure is simply the statement that is required to explain the step. For instance to express a formula code GrossPay = TotalHours * HourlyRate In the example above I chose to capitalize the first letter of each word and run the words together to form "data elements" that might have been used in an IPO. To ask the user of the program to enter the TotalHours data element in the example above two pseudo code words are used. It is known as a prompt. OUTPUT Please enter the total hours for this employee. INPUT TotalHours Notice how the pseudo code words pop out? Also notice that the data element name is used in the INPUT statement. The OUTPUT tells the user what is to be input in the next line. Was it total hours or perhaps overtime hours. The user needs to know what the program needs for each input When decisions are required the IF statement is used. The first one shown is known as a NULL if. In the NULL if there is no "false" path IF TotalHours > 40 THEN OUTPUT "You have exceeded the regual time. You are not authorized to work overtime" ENDIF In this next example the if is more complex. It is known as an IFTHENELSE. It is used to create two paths for the program. One path is for the condition when it is true the other when it is not true (it is false) IF TotalHours > 40 THEN OTHours = TotalHours - 40 RegHours = 40 ELSE RegHours = TotalHours OTHours = 0 ENDIF GrossPay = (RegHours * RegRate)+(OTHours * RegRate * 1.5) DISPLAY "Total Gross Pay is ",GrossPay Many true and many false statements can be placed in each part of the IF statement. True statements, that is statements that need to be executed if the IF is true go between the THEN and the ELSE. Those that are executed when the IF is false are placed between the ELSE and the ENDIF. If your IF structure does not require an ELSE the ENDIF is still required after all true statements. The third structure is the iteration or loop structure. Lets code a small multiplication table OUTPUT "Enter a number for the Table -> " INPUT TheNumber tableSize = 10 tableCount = 1 DOWHILE tableCount 2 2 times 1 equals 2 2 times 2 equals 4 2 times 3 equals 6 2 times 4 equals 8 2 times 5 equals 10 2 times 6 equals 12 2 times 7 equals 14 2 times 8 equals 16 2 times 9 equals 18 2 times 10 equals 20 In addition you can create modules. An example of using modules follows. START (this is the main program) main program code starts here now you need to call a module to do some code CALL MyModule(parm1, parm2) parm1 one now has a value that was calculated in MyModule STOP (end of the main program) MyModule (arg1, arg2) put some code here arg1 = some equation here to return a value to the main program RETURN
