Usually you start with just one feature, like std::map instead of OpenSSL's abomination of a hashmap library or rolling your own.

Of course you should use std::unordered_map instead of std::map because the latter is actually a treemap, but you probably don't know that when you first learn it...

Nah, I prefer to just use C, because at least I can parse the quite sane and helpful error diagnostics when I omit a semicolon or something, instead of getting 15 pages of unreadable garbage dumped into my lap by the oh-so-wonderful C++ standard library.

(Which quite frankly isn't much of a "standard" when there's about a dozen different real world interpretations of the code depending on which flavor of which compiler from which year that you're using.)

I also don't have to wait eons for my code to compile. Really, the mental and computational load of C has got to be 1/10 of C++.

What a nightmare C++ is, and it just keeps getting worse every year thanks to the incompetent standards committee.

LPT: scroll up to the top of the error message. Typically it's "could not match this function call" followed by "here's all the things that might match and why they don't match"
