A deeper understanding requires a lot of questioning.

Use the 5 W's (What, Who, Where, When , Why) and 1 H (How?)

A big part of programming is problem-solving. Find the cause and diagnose the problem. Figure how to solve it.

I didn't mod you down, so I can only guess what part of your post bothered others. What do you think "syntactical" means? The syntax of C is very easy to learn, and C++'s syntax is not all that hard to learn either. The tricky parts of the language are primarily about things like what is guaranteed behavior by the standard, how do compilers actually implement it, and how have these things evolved.

Using libraries written by others is a great way to learn how to write clean interfaces, which is a very good thing indeed, but it has little to do with this thread.

If you like the type of things in the video, what happens when you compile this C program?

#include <stdio.h>

int main(void) {
  char a[2] = "42";
  printf("%c%c\n", a[0], a[1]);
}

What does this C++ program do?

#include <iostream>

int main() {
  volatile char const *s = "Hello,world!";
  std::cout << s << '\n';
}

The best way to learn new syntactical concepts is to use libraries written by others.

syntax is good to know but in terms of deeper understanding it realy means understanding the underlying language of C++. What is really going on is the question.

What does this C++ program do?

#include <iostream>

int main() {
  volatile char const *s = "Hello,world!";
  std::cout << s << '\n';
}

What does this C++ program do?

#include <iostream>

int main() {
  volatile char const *s = "Hello,world!";
  std::cout << s << '\n';
}

Might be better if fewer people knew this one. Volatile variables are rarely useful, except in specific fields, and that's a bad example of their use. It's also something that can easily be learned when it is encountered as opposed to being part of a rounded C/C++ knowledge base. If it weren't for its contagious semantics, volatile would be better off in a rarely used c header, like va_args and friends.
