Flowchart Examples For Beginners
A flowchart is a graphical representation of a process or algorithm. It uses various shapes and symbols to depict the steps involved in a process, making it easier to understand and analyze. Whether you are a beginner or an experienced programmer, flowcharts can be a useful tool for visualizing and designing your programs. In this article, we will provide some flowchart examples for beginners to help you get started.
Before we dive into the examples, let’s familiarize ourselves with some common flowchart symbols:
- Start/End: Represents the beginning and end of a process.
- Input/Output: Represents input or output of data.
- Process: Represents a specific action or operation.
- Decision: Represents a conditional statement or question.
- Connector: Represents the flow of control from one part of the chart to another.
Example 1: Simple Calculator
In this example, we will create a flowchart for a simple calculator program that performs basic arithmetic operations.
In the above flowchart, the user is prompted to enter two numbers and select an operation. The program then performs the selected operation and displays the result.
Example 2: Guessing Game
In this example, we will create a flowchart for a guessing game program. The program generates a random number between 1 and 100, and the user has to guess the correct number.
The flowchart starts by generating a random number and initializing the guess count. It then prompts the user to enter a guess and checks if the guess is correct. If the guess is incorrect, the program provides feedback and updates the guess count. The flowchart continues until the user guesses the correct number or reaches the maximum guess count.
Example 3: Factorial Calculation
In this example, we will create a flowchart for calculating the factorial of a number. The factorial of a number is the product of all positive integers less than or equal to that number.
The flowchart starts by prompting the user to enter a number. It then calculates the factorial by multiplying the number with its preceding integers until it reaches 1. The calculated factorial is then displayed.
Example 4: Sorting Algorithm
In this example, we will create a flowchart for a simple sorting algorithm called bubble sort. Bubble sort compares adjacent elements and swaps them if they are in the wrong order, repeating this process until the list is sorted.
The flowchart starts by initializing the list and setting the pass counter. It then compares adjacent elements and swaps them if necessary. The flowchart continues until the pass counter reaches the length of the list, indicating that the list is sorted.
Example 5: Login System
In this example, we will create a flowchart for a simple login system. The program prompts the user to enter a username and password, and checks if the entered credentials are valid.
The flowchart starts by prompting the user to enter their username and password. It then checks if the entered credentials match the stored username and password. If the credentials are valid, the program displays a success message. Otherwise, it displays an error message.
