This is also why many people will suggest you find a project. As it will start you programming somethin and very often something you have some kind of passion or need for. But if you cannot think of a project to do, then I would look for guided projects or programming gamified like kattis.com or leetcode.com. I would highly suggest you do not watch tutorials without coding anything, as this is almost always wasted... Source: over 1 year ago
Have you been on https://kattis.com? It’s full of C++ practice exercises that you can sort by level of difficulty and run through tests to check. My teacher had us use it for practice. Hope it helps! Source: over 2 years ago

This, and OP should practice handling the stress. Find a friend to do interviews with, or give yourself a timer, or whatever. codingame.com is a good alternative if you want to try dealing with a timer and don't want to be able to cheat. Source: almost 2 years ago
Just jumped to codingame.com and start (cant) solving puzzles. Source: almost 2 years ago
Personally, I like codingame.com (completely free unless you are an employer) - Their simple puzzles are great places to get an idea of how programming works and the kinds of problems they solve. I think the first puzzle I was able to solve as a beginner in a few days. Source: about 2 years ago
I believe it's possible to use rust in codingame.com. Is that ok for you? Source: about 2 years ago
