C Programming with CMake 🎯

Welcome to this comprehensive guide on C Programming using CMake! Whether you're a beginner or an intermediate learner, this tutorial will walk you through the basics and advanced concepts of C programming with practical examples.

What is C Programming? 📝

C is a powerful, general-purpose programming language that offers low-level access to memory and hardware, making it a popular choice for system programming, embedded systems, and more.

What is CMake? 📝

CMake is an open-source build system that helps manage and build projects in various programming languages, including C and C++. It's cross-platform, which means you can use it on Windows, Linux, and macOS.

Setting Up CMake 💡

To start using CMake, you'll need to install it on your system. Here's a quick guide for different operating systems:

Windows: Download the latest CMake installer from here.
Linux: Install CMake using your package manager. For example, on Ubuntu, run sudo apt-get install cmake.
macOS: Install CMake using Homebrew. Run brew install cmake.

Creating a CMake Project ✅

Let's create a simple CMake project. Create a new directory, navigate into it, and create three files:

CMakeLists.txt
main.c
hello.h

hello.h

#ifndef HELLO_H
#define HELLO_H

void printHello();

#endif

main.c

#include "hello.h"

int main() {
    printHello();
    return 0;
}

CMakeLists.txt

cmake

cmake_minimum_required(VERSION 3.0)
project(CMakeHello)

add_executable(CMakeHello main.c)

include_directories(.)

function(printHello)
    message(STATUS "Hello, World!")
endfunction(printHello)

Now, open a terminal, navigate to your project directory, and run cmake . to generate the build files. Then, build the project with cmake --build .. Your executable, CMakeHello, should now be in the build directory.

C Types 💡

Understanding C types is crucial for writing effective C programs. Here's a list of some common C types:

char: Used for storing single characters and small integers.
int: Used for storing integers.
float: Used for storing floating-point numbers.
double: Used for storing double-precision floating-point numbers.
void: Represents the absence of a value.
bool: Represents Boolean values (true and false).
