WHAT IS PROGRAMMING?
Programming is the process of writing instructions that tell a computer what to do.
A program may instruct a computer to:
• Calculate information
• Display text
• Process data
• Store information
• Communicate with databases
• Display a website
• Automate repetitive tasks
• Control devices
• Analyze information
• Run an application
• Process images
• Interact with users
PROGRAMMING VS CODING
The terms programming and coding are often used interchangeably, but they can describe slightly different ideas.
CODING
Coding generally refers to writing instructions in a programming language.
PROGRAMMING
Programming is broader and can include:
• Understanding the problem
• Designing a solution
• Writing code
• Testing
• Debugging

PROGRAMMING FUNDAMENTALS
VARIABLES
A variable is a named reference used to store or represent information.
For example, a program may need to store:
• A person's name
• Age
• Temperature
• Product price
• Number of patients
• Examination score
DATA TYPES
Programming languages commonly distinguish between different types of data.
Common examples include:
• Strings
• Integers
• Floating-point numbers
• Booleans
• Lists
• Arrays
• Objects
• Dictionaries
Understanding data types helps programmers work with information correctly.
STRINGS
Strings represent text.
Examples include:
• "HarperHoleLearning"
• "Hello"
• "Nursing"
• "Programming"
String operations can include:
• Combining text
• Searching
• Replacing text
• Changing capitalization
• Extracting sections of text
NUMBERS
Programs frequently work with numerical values.
Examples include:
• Whole numbers
• Decimal numbers
• Measurements
• Prices
• Scores
• Quantities
BOOLEAN VALUES
Boolean values represent two logical states.
Common examples are:
• True
• False
Boolean logic is essential for conditions and decision-making in programs.
OPERATORS
Operators allow programs to perform calculations and comparisons.
Examples include:
• Addition
• Subtraction
• Multiplication
• Division
• Comparison
• Equality
• Logical operations
CONDITIONAL STATEMENTS
Conditional statements allow programs to make decisions.
A simplified concept is:
IF condition is true
→ perform one action
ELSE
→ perform another action
LOOPS
Loops allow a program to repeat instructions.
Common types include:
• For loops
• While loops
Loops are useful when the same operation needs to be performed repeatedly.
FUNCTIONS
A function is a reusable block of code designed to perform a particular task.
Functions can:
• Accept inputs
• Process information
• Return results
Using functions can make programs easier to organize, test, and maintain.
PARAMETERS AND ARGUMENTS
Functions often use parameters to receive information.
For example, a function designed to calculate an average might receive a collection of numbers as input.
Understanding parameters and arguments becomes increasingly important as programs become more complex.
LISTS AND ARRAYS
Lists and arrays allow programs to store collections of information.
Examples include:
• Patient names
• Product prices
• Exam scores
• Inventory items
• Website visitors
DICTIONARIES AND KEY-VALUE DATA
Some programming languages provide structures that store information using key-value relationships.
For example:
Name → "Alex"
Age → 30
Department → "Nursing"
This type of structure is particularly useful for representing organized information.
OBJECTS
Objects allow programs to group related information and behavior.
Object-oriented programming commonly uses concepts such as:
• Classes
• Objects
• Properties
• Methods
• Encapsulation
• Inheritance
• Polymorphism
OBJECT-ORIENTED PROGRAMMING
Object-oriented programming, or OOP, is a programming approach based around objects and classes.
Important concepts include:
• Classes
• Objects
• Encapsulation
• Inheritance
• Polymorphism
• Abstraction
Beginners do not need to master all OOP concepts immediately.
ALGORITHMS
An algorithm is a structured sequence of steps used to solve a problem.
For example:
Problem:
Find the largest number in a list.
A simplified algorithm might be:
1. Start with the first number.
2. Compare it with the next number.
3. Keep whichever is larger.
4. Continue through the list.
5. Return the largest value.
FLOWCHARTS
Flowcharts visually represent the steps of a process.
Common symbols represent:
• Start
• Process
• Decision
• Input
• Output
• End
Flowcharts can help beginners understand program logic before writing code.
PSEUDOCODE
Pseudocode is an informal way of describing an algorithm using human-readable instructions.
Example:
START
Get the user's score.
IF score is 75 or higher
Display "Passed"
ELSE
Display "Needs improvement"
END
Pseudocode allows learners to focus on logic before worrying about programming-language syntax.
INPUT AND OUTPUT
Programs often receive input and produce output.
INPUT
Information provided to the program.
Examples:
• Keyboard input
• File data
• Database records
• User selections
• Sensor readings
OUTPUT
Information produced by the program.
Examples:
• Text
• Numbers
• Reports
• Charts
• Files
• Screens
ERRORS IN PROGRAMMING
Programming errors are normal.
Common types include:
• Syntax errors
• Runtime errors
• Logic errors
• Type errors
• Configuration errors
SYNTAX ERRORS
A syntax error occurs when code does not follow the rules of the programming language.
Examples may include:
• Missing punctuation
• Incorrect keywords
• Incorrect indentation
• Missing brackets
RUNTIME ERRORS
A runtime error occurs while a program is running.
Examples include:
• Trying to access unavailable data
• Dividing by zero
• Opening a missing file
• Using an invalid operation
LOGIC ERRORS
A logic error occurs when a program runs but produces the wrong result.
These can be particularly difficult for beginners because the program may appear to work normally.
DEBUGGING
Debugging is the process of finding and correcting errors in a program.
A useful debugging approach is:
1. Reproduce the problem.
2. Identify where it occurs.
3. Check assumptions.
4. Examine variables and outputs.
5. Isolate the problem.
6. Correct the code.
7. Test again.
READING ERROR MESSAGES
Error messages are not simply failures.
They often provide useful information about:
• What went wrong
• Where the problem occurred
• Which operation caused the problem
Learning to read error messages is one of the most valuable beginner programming skills.
COMMENTS
Comments are notes included in source code to explain what the code does.
Comments can help:
• Explain complicated logic
• Document decisions
• Help teammates understand code
• Make future maintenance easier
CODE FORMATTING
Readable code is easier to understand and maintain.
Good practices include:
• Consistent indentation
• Meaningful variable names
• Appropriate spacing
• Reasonable function sizes
• Clear organization
NAMING VARIABLES
Variable names should communicate what they represent.
For example:
total_sales
is generally easier to understand than:
x
Meaningful naming becomes increasingly important in large programs.
VERSION CONTROL
Version control allows developers to track changes to code over time.
Git is one of the most widely used version-control systems.
It can help developers:
• Track changes
• Restore earlier versions
• Collaborate
• Create branches
• Merge changes

Examples include:
• Visual Studio Code
• PyCharm
• IntelliJ IDEA
• Eclipse
• Xcode
• Android Studio
• RStudio
COMMAND LINE
The command line provides a text-based way to interact with a computer.
Basic command-line skills can help programmers:
• Navigate folders
• Run programs
• Install packages
• Manage files
• Use development tools
• Work with Git
PACKAGES AND LIBRARIES
Programming languages often provide libraries or packages containing reusable code.
Instead of creating every feature from scratch, programmers can use existing libraries for tasks such as:
• Data analysis
• Web development
• Image processing
• Mathematics
• Artificial intelligence
• Networking
APPLICATION PROGRAMMING INTERFACES

For example, an application may use an API to retrieve:
• Weather information
• Maps
• Payment information
• Healthcare data
• Financial data
• Social-media information
DATABASES
Many applications need to store information.
Databases can store:
• User accounts
• Products
• Orders
• Patient records
• Transactions
• Messages
Common database technologies include:
• MySQL
• PostgreSQL
