Tutorial — primer-programa

Learn by programming: follow each step, write your own code, then apply it to the course assignment.

What you will build

A CMake console executable that prints a greeting.

  1. 1

    Create the project folder

    Create `hola-cpp/` with `CMakeLists.txt` and `main.cpp`. Open the folder in VS Code or your preferred IDE.

    Tip: Environment: /en/introduccion/entorno/

  2. 2

    Configure CMake

    Run `cmake -B build` from the root. CMake generates build files inside `build/`.
    
    								cmake_minimum_required(VERSION 3.16)
    project(hola_cpp CXX)
    add_executable(hola main.cpp)
    							
  3. 3

    Write main.cpp

    Print a greeting. This is the same skeleton you will use in class and assignments.
    
    								#include <iostream>
    
    int main() {
        std::cout << "Hola, Computacion II!" << std::endl;
        return 0;
    }
    							
  4. 4

    Build and run

    Run `cmake --build build` then `./build/hola` (path may vary). You should see the message in the terminal.
