AGENDA

• Introduction to C++17
• First program: Hello World
• Compile with g++
• Intro to Makefile
• Intro to CMake
• Project structure
• Mini exercises

Why C++?

• Widely used in embedded, power electronics, and system testing
• High performance and control
• Large ecosystem (STL, libraries)
• Industry standard for engineering projects

Hello World in C++

#include <iostream>
int main() {
    std::cout << "Hello, world!" << std::endl;
    return 0;
}

Compile and Run

g++ main.cpp -o main
./main

Makefile (Intro)

• Automate compilation Example Makefile:

all:
    g++ main.cpp -o main
clean:
    rm -f main

• Run:

make
make clean

CMake Basics

• Cross-platform build system generator
• Easier for larger projects

Minimal CMakeLists.txt:

cmake_minimum_required(VERSION 3.10)
project(HelloWorld)
add_executable(main main.cpp)

Building with CMake

mkdir build
cd build
cmake ..
make
./main

Project Structure

myproject/
├── src/
│   └── main.cpp
├── inc/
├── CMakeLists.txt
└── build/

Mini-Exercises

Exercise 1

1. Create a new folder cpp_project
2. Write main.cpp with Hello World
3. Compile with g++ and run

Exercise 2

1. Write a Makefile to compile main.cpp
2. Use make to build and make clean to remove binaries

Exercise 3

1. Create CMakeLists.txt as shown
2. Build with CMake in build/
3. Run the program

Survival Package (C++ Project Setup)

• g++ main.cpp -o main
• Makefile: make, make clean
• CMake: cmake .. && make
• Project structure: src/, inc/, build/

Wrap-Up

• Wrote and compiled first C++ program
• Learned Makefile basics
• Used CMake to build project
• Understood standard project structure
