Fundamentals of Algorithmization and Programming
Welcome to the world of programming! In this presentation, you will learn about the concept of algorithms and programming languages used to create them. Let's dive in!

The Algorithm Concept
The art of solving a problem
An algorithm is a sequence of steps required to solve a problem or complete a task. It's like solving a maze: you need step-by-step instructions to reach your goal.
Efficiency is key
Efficiency is important when designing an algorithm. It's like timing yourself while solving the maze: you want to solve it as quickly as possible!
Algorithm components
Every algorithm is made up of inputs, outputs, and processes. It's like developing a film: you need to have all the key elements to produce a stunning result!
Graphic Representation of Calculation Processes
Visualize your processes
Calculations can be complex, but you can make them easier to understand by breaking them down into simple processes and visualizing them. It's like building a Lego house: one block at a time!
Flowcharts and diagrams
Flowcharts and diagrams are commonly used in programming to represent calculation processes. It's like drawing a map: you need to have a clear idea of where you're going!
Understandable for everyone
Visual representations of calculation processes can help others understand complex programs. It's like explaining a recipe using pictures: everyone can follow along!
Types of Calculation Processes
1
Sequential
Processes that occur one after the other, in a predetermined order.
2
Conditional
Processes that depend on a particular condition or set of conditions.
3
Iterative
Processes that repeat themselves a predetermined number of times or until a certain condition is met.
General Information about Programming Languages
What are programming languages?
A programming language is an artificial language used to give instructions to a computer. It's like communicating with a person who only speaks a foreign language!
Types of programming languages
There are many different programming languages, each with its strengths and weaknesses. It's like choosing the right tool for each job!
Popular programming languages
Some popular programming languages include Java, Python, and C++. It's like picking a favourite colour: different people have different opinions!
Basic Elements of Language
Assignment operator
The assignment operator sets a value to a variable. It's like labelling a jar: you need to know what's inside!
Input operator
The input operator allows the user to enter data into a program. It's like ordering a pizza: you need to specify what you want!
Output operator
The output operator displays information to the user. It's like printing a receipt: you need to know what you ordered!
Programming the Computational Process
1
Define the problem
The first step in programming is defining the problem you want to solve. It's like identifying the destination before starting a journey!
2
Design the solution
Once you've defined the problem, you need to come up with a solution. It's like choosing the route to take to your destination!
3
Write the code
Programming involves writing code that the computer can understand. It's like writing a love letter: you need to use the right words!
Programming a Cyclic Calculation Process
What is a cyclic process?
A cyclic process is one that repeats itself a predetermined number of times or until a certain condition is met. It's like brushing your teeth: you need to repeat the same process every day!
A cyclic calculation process
Programming a cyclic calculation process involves creating a loop that repeats itself until a condition is met. It's like a hamster running on a wheel: it keeps going until it reaches its goal!
Debugging a cyclic process
Debugging a cyclic process involves finding and fixing errors in the loop. It's like finding and fixing a broken toy: you need to identify the problem and fix it!
