ALGORITHM
At the core of programming are algorithms that determine the flow of work and the paths to be followed . Just as a work is planned before it begins to be done , a work plan must be set before it begins/switches to coding . The software reads and processes the code written in this plan in a specific order . Hence the algorithm should be set up very well . Established algorithms gain visual richness with flow diagrams .
.After reading this article :1) to learn to build algorithm
2) you will be able to obtain the algorithms visually with Flow Diagrams .
What Is The Algorithm ?
It is the working logic that shows which paths a program will follow . The algorithm is not a programming language . It is a set of methods that guide programming languages . The algorithm for encoding in each language is implemented / implemented . For example, when you start a game that we see the main screen after the game to come is an algorithm job .
When writing an algorithm , the resources, controls, or operations used to run the application must be explicitly stated . In addition, a fully supported algorithm must check all the possibilities and determine what to do in undesirable situations .
!!! [COLOR="DarkOrchid"!!! For example, in a student application, the student scores algorithm is subtracted . Once the student is selected, the user is asked to select schools worth the score . When writing the application, it is considered that this value will be of the int data type ; the score of the school the user enters must be checked before it is assigned to the variable . If a value is entered that the int data type will not hold ( i.e. a school is selected where the student's score is not sufficient ), the application stops unexpectedly or produces unintended results at the time of study . In addition , the error of the system affects the image of the application in a bad way for the content of a message that the user cannot understand .[/COLOR]
[COLOR="White"]Data Entry[/COLOR]
Often at run time , an outside information must be entered to complete the operation. The data that the algorithm needs to work can be retrieved from the person who initiated the process or from a specified source . The process will not continue until this information is provided ..
Decisions
Decision and control structures are the most important concepts that guide the flow of the algorithm . The data entered or obtained as a result of the transaction is controlled according to the purpose of the transaction and the algorithm flow is directed to the desired ******** according to the result ..
Operations/B]
Operations such as changes on data , new value assignments are needed throughout the flow of the algorithm . While the algorithms are being set up, simple writing of the operations increases readability .
Algorithms work in step order and continue to work with the next step , unless they are directed to a different ******** as a result of decision structures . .
let's do one example: wire money from an ATM
1-Go To Your Bank's ATM
2-Get Your Credit Card
3-Look how many are in line
4-if the number of people is more than 2, return to 3
5-line up if the number of people is less than 2
6-switch to ATM if there is no queue
7-Take Out Your Credit Card
8-find the option Send money or transfer money immediately after entering the customer menu with the card.
9-then, find the bank account " option and fill in the necessary information and required information. Probably your account number or IBAN and, of course, T.C. ID number will be requested.
10-it is possible to make a transfer from your account by confirming the transaction afterwards.
In order for this algorithm to work , every probability ( in my example , it may not be every probability ) is reviewed and the algorithm flow is directed to the required ********s . For example, the pass to no ATM command must be given the necessary commands to switch to the ATM . The data needed by this algorithm is either given by the user or determined before the operation begins . Data such as number of people in the queue , atm card are provided by the user ; the person to whom you will make the transfer is pre-determined .
Article-by-Article algorithms are easy to read, but it is often impossible to see the whole of the operation . Flow diagrams allow to show algorithms in visual form , thus making them more comprehensible . Various symbols are used according to the types of operations to be performed in the algorithm ..
It is the symbol of the algorithm that shows which stage it will start and when it will finish . In the flow diagram representing an algorithm , there must be one start and one end symbol .
Calculating University Education Grade/B]
The success grade of a course at the university is usually calculated with a midterm and a final grade . The coefficient of the visa grade is lower than the final . If the result is 50 or higher, the student passes, and if 50 is lower, the student remains . This example shows the calculation of the success score, which is weighted by 30% of the visa and 70% of the final, with the flow diagram .
[/QUOTE]
1. The number of the student whose grade will be calculated is taken from the user .
2. The student's midterm and final grades are drawn from the database .
3. If the final grade is 28 or lower, the student remains and is 9. you go to the stage . In this case , even if the visa note is 100, the resulting collected note is under 50 . Therefore, it is certain that the student stays . Making such a check prevents unnecessary operations .
4. The visa variable is assigned 30% of the visa grade from the database .
5. The final variable is assigned 70% of the visa grade from the database .
6. The result variable is assigned the sum of the final and visa values .
7. Check whether the result value is greater than 50 .
8. If the result is greater than 50, a message saying "You have passed" will be displayed on the screen . The algorithm shuts down .
9. If the result is less than 50, a message saying "You Are Left" will be displayed on the screen .
