Zenva Learn Object-Oriented C++ by Building a Game Link to heading

A while ago I bought a bunch of Zenva programming courses from Humble Bundle as some of the courses covered C++, which I hadn’t touched since university, but was becoming a language that I was dealing with semi frequently in my new role.

So, this was a “refresher” on the C++ world and where it had come to in the last 10 years or. The course I did can be found here: https://academy.zenva.com/product/learn-object-oriented-cpp-by-building-a-game/

The course itself was fairly well organised in terms of being logical and easy to follow. I particularly liked the use of Replit which was great and was my first introduction to the in browser IDE.

It did feel like for the author of the course, it might not have been his primary/first language.

My impression of the C++ language after having not touched it for many years were not great. It feels like the language offers a massive amount of flexibility in terms of how to write particular bits of code/implement solutions, which sounds good, but it comes at the expense of there not being a clear/idiomatic way to do things. An example of this is that there are so many ways to include code files that the advice was to add “#ifndef LIB_FILE …” at the top of each file to prevent including the same libraries/files multiple times.

Additionally, I found the syntax quite clunky (e.g. “->function()” vs “.function()”) and overly verbose at times.

There was also a bug where if a player picked up an “item”, the definition of which looks like:

struct item {
  std::string name;
  int damage;
  int health;

and has an instance like (note that damage property is left uninitialised):

  item healingPotion;
  healingPotion.name = "Healing Potion";
  healingPotion.health = 50;

when you come to apply (or “pick up”) the item:

void Player::pickUpItem(item item) { 
  damage += item.damage;

for some reason the “damage” is increased by a random value (sometimes “6”)?

I’ve created a public Replit reproducing the issue here: https://replit.com/@srkiNZ/TestingCPPInt?v=1

I didn’t get to the bottom of this one, however, it’s unexpected behaviour like this that doesn’t give much confidence around the safety of C++ as a language. The tradeoff is the performance and the portability.
