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


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

SPECIALIZATION


Whether you eventually choose web development, data analysis, AI, healthcare technology, mobile development, automation, or another field, the fundamental programming concepts remain valuable.


The goal is not simply to learn how to write code.


The goal is to learn how to solve problems with code.



HARPER RECOMMENDATION


Harper recommends Python as a strong starting point for beginners who are unsure where to begin.


Start with:


• Variables

• Data types

• Conditions

• Loops

• Functions

• Lists

• Dictionaries

• Basic error handling

• File handling

• Modules

• Simple projects


CS50P, freeCodeCamp, Python.org, Exercism, and Python Tutor can provide a strong combination of structured lessons, documentation, practice, and visualization.


If your primary goal is web development, consider learning:


HTML



CSS



JavaScript


If your goal is data analysis or AI:


Python



Statistics



pandas / NumPy



Data Visualization



Machine Learning


If your goal is healthcare technology, combine programming with:


• Healthcare data

• Statistics

• Research

• Health informatics

• Data privacy

• Electronic health records


Most importantly, do not measure your progress by how much code you can memorize.


Measure it by how confidently you can understand a problem, design a solution, write code, identify errors, and improve your program.
