• User-Defined Types - Enumerations, structures, type aliases
• Arrays and Containers - C-style arrays, std::array

Advanced

• Object-Oriented Programming - Classes, inheritance, polymorphism

• Smart Pointers - unique_ptr, shared_ptr, RAII principles
• STL - Containers, algorithms, iterators
• Concurrency - Threading, synchronization, async operations
• Modern C++ - C++11/14/17/20 features and best practices

Prerequisites

• C++ compiler supporting C++17 or later (GCC 7+, Clang 5+, MSVC 2017+)
• Basic understanding of programming concepts
• Command-line familiarity (optional but recommended)

Quick Start

Compilation

# Basic compilation
g++ -std=c++17 -Wall -Wextra chapter_03_functions.cpp -o functions

# With debugging symbols
g++ -std=c++17 -g -Wall -Wextra chapter_03_functions.cpp -o functions

# Optimized build
g++ -std=c++17 -O2 -Wall -Wextra chapter_03_functions.cpp -o functions

Execution

./functions

Compiler Flags

Flag	Purpose
-std=c++17	Enable C++17 standard
-Wall	Enable all standard warnings
-Wextra	Enable additional warnings
-g	Include debugging information
-O2	Enable optimization level 2
-o <name>	Specify output filename

File Organization

Each chapter file follows a consistent structure:

/*=============================================================================
 * CHAPTER N: TOPIC NAME
 * =============================================================================
 * 
 * C++ Development Course - Consolidated Examples
 * Original Author: Faranak Rajabi
 * 
 * This file contains X code example(s) from Chapter N.
 * 
 * USAGE:
 *   - Review each example section
 *   - Uncomment the code you want to test
 *   - Compile: g++ -std=c++17 -Wall thisfile.cpp -o program
 *   - Run: ./program
 =============================================================================*/

#include <iostream>
#include <string>
#include <vector>
#include <algorithm>

// ============================================================================
// EXAMPLE 1: Title
// ============================================================================
// Example code with inline documentation

// ============================================================================
// EXAMPLE 2: Title
// ============================================================================
// Additional examples...

// ============================================================================
// MAIN FUNCTION
// ============================================================================
int main() {
    // Test code here
    return 0;
}

Usage Guidelines

Working with Examples

1. Review - Examine the example code and comments
2. Uncomment - Activate examples that are commented out
3. Modify - Adapt the main() function to test specific examples
4. Compile - Use appropriate compiler flags
5. Execute - Run and verify output

Example Workflow

// Locate desired example in chapter file
// Example: chapter_08_strings.cpp

// In main() function, add test code:
int main() {
    std::string text = "Example";
    std::cout << text << std::endl;
    return 0;
}

Compile and run:

g++ -std=c++17 -Wall chapter_08_strings.cpp -o test && ./test

Important Notes

Code Extraction

Examples were extracted from PDF course materials using automated parsing. Some considerations:

• Snippets - Some examples are illustrative code fragments rather than complete programs
• Context - Certain examples may require additional headers or supporting code
• Formatting - Minor formatting adjustments may be needed for compilation
• Completeness - Examples without main() functions are commented out by default

Making Examples Compilable

If an example is commented out:

/*
std::string message = "Hello";
std::cout << message << std::endl;
*/

Add to main():

int main() {
    std::string message = "Hello";
    std::cout << message << std::endl;
    return 0;
}

Build Systems

While not required, these examples can be integrated into larger build systems:

CMake Example

cmake_minimum_required(VERSION 3.15)
project(CPPExamples CXX)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

add_executable(functions chapter_03_functions.cpp)
add_executable(strings chapter_08_strings.cpp)

Makefile Example

CXX = g++
CXXFLAGS = -std=c++17 -Wall -Wextra -O2

functions: chapter_03_functions.cpp
	$(CXX) $(CXXFLAGS) $< -o $@

strings: chapter_08_strings.cpp
	$(CXX) $(CXXFLAGS) $< -o $@

clean:
	rm -f functions strings
