I´m 15, without any prior coding experience learning C++ from LearnCPP, I had a few suggestion to learn using some graphilac interface. I got recommended two, but I can´t really decide which one to choose.

Can anyone help me?

Is for me better Raylib, or SFML, I want to make simple games like flappy bird, tic tac toe, or simple programms like to do lists and stuff. Which one will suite my needs the best?

Thanks for answers!

Hi, I´m 15, learning C++ with LearnCPP. I´m currently on chapter 14, where is introduction into OOP, classes...

For the theoretical part, I think I understand everything up to this point pretty good, but when it comes to real programming, I´m a little lost. I think the problem is that I don´t have enough of the practical experience, to fully understand it. I tried using AI to give me some exercises, and projects I can build, but none of that really makes difference, cause it is all theme specific and I just can´t figure out, how to use the code in real applications.

Do you have any ideas how can I get better not at understanding the theory, but really building something?

All the people are saying, "Just build something, you learn by experience", but that isn´t the problem, the problem is what to build.

Do anyone have any ideas?

I am currently 15 and learning C++ with LearnCPP, without any prior coding experience (except for scratch, but lets not count that) I´m on chapter 13 (Enum, Struct...)in LearnCPP. I finished writing this program ( it has nothing to do with what I´m currently learning about), and wanted to ask some things.

1. Is there anything that needs to be changed? Are there some things that may function incorrectly in some instances, or do i have any bad practise I should fix?

2. Should I also focus on learning things like for example what is used in this program, the sstream library things and stuff? Because currently, it looks terrifying to use something like this. ( I spent very long time figuring out how to do the check if the input is a integer, and at the end I ended up on some StackOverflow forum.) Is it bad to find information like this, or id it completely normal?

Also one more question, I´m currently 1 month in learning cpp, and I already learned this many things, that I´m proud of. How long will it approximately take to learn all the stuff so I can comfortably write any code that I need.

Thanks for answers!
