Hello everyone, Dear TurkHackTeam members, in this topic, we will make a general introduction to algorithms. What is an algorithm ? What is a flowchart ? We will learn about these concepts and then write an algorithm with a flowchart. I hope it will be a useful topic for you
What is an Algorithm?
The algorithm emerged in the 9th century, initially introduced by Al-Khwarizmi, or his full name Abu Abdullah Muhammad ibn Musa al-Khwarizmi. Initially appearing in computer science and mathematics, but now central to our lives, an algorithm is the path followed to solve a problem or achieve a goal.
Algorithms are finite structures, with two essential points in every algorithm: starting and ending points.
What is a Flowchart?
A flowchart, or flow diagram, is the graphical representation of an algorithm using specific symbols.
Flowchart Symbols and Their Meanings
Now I'll draw a flowchart indicating whether the entered number is positive or negative.
We mentioned that there are absolute entry and exit points in the algorithm. Let's start by creating our flowchart from the entry point. I'll use the Flowchart Maker & Online Diagram Software website for this drawing.
First, we specify our starting point.
We will establish connections between our shapes using arrow symbols.
Now we will take a number from the user, and in the next step, we will make decisions based on certain conditions regarding the number we received.
One of the first checks we will perform is whether the number taken is equal to 0. If it is equal, the user will be directed to enter a new value.
Finally, the last check we will perform is whether the number is greater than zero or less than zero. After this query, once the output is given, our flowchart will terminate
Here, if the query we will perform returns True if the number is greater than zero, it will lead to a positive output; if it returns False, it will lead to a negative output. Finally, after the last output is received, the flowchart will reach the endpoint, and our diagram will be completed.
