Hello fellow C++ Developers!

This week is another milestone in the “Introduction to C++” posts of our LearnCPlusPlus.org website, we start to add posts about Object-Oriented Programming, and we will dive into Classes & Objects in the next few weeks so keep following along. 

This week’s topics include

  • What is the main function in C++?
  • How can we define and declare functions?
  • What is the difference between declaration and definition of functions?
  • What does void mean?
  • How we use the return type in function?
  • How we can overload a Function?
  • What is overloading mean in C++?
  • How we can pass the parameters of a function by reference?

This week’s topics will teach you all this and particularly details about functions.

If you are a beginner, new to C++, or if you are a Delphi developer and want to learn or remember the basics of C++, these posts are good to improve your programming skills.

We keep adding new C++ blogs for C++ Builder, Dev-C++. Most are also compatible with other C++ compilers. Please visit our LearnCPlusPlus.org website for great posts from basics to professional examples, full code, snippets, and a lot more. 

Before we start on the details of Object Oriented Programming let’s learn about functions in C++. Here are our post picks from the last week for C++ beginners,
