Help in c++

Question

In python when i want to know function, i use

help("dir")

What is alternative for c++?
For example, i want know function sizeof()

Answer 1

For functions I like cplusplus.com: http://www.cplusplus.com/reference/algorithm/copy_if/

But, sizeof is not a function. (It is an operator like + or -). An alternative is cppreference.com. It has info about everything, however it can be very technical:
https://en.cppreference.com/w/cpp/language/sizeof

You can always google for easy to read tutorials of course.

Answer 2

Schindlabua Unfortunately, in your answer there is no direct description of the help call from the module. I know what sizeof is, but is it really impossible to call a quick description of a parameter or function? one line. But i appreciate your attention to my question

Answer 3

Petr If at all possible, I recommend coding on a desktop PC. Programming on a mobile phone is really slow and cumbersome.
With a proper keyboard and mouse, and the ability to have many windows open at the same time, you are at least 10 times faster.

I appreciated your subtle humor. fun. however, I only write codes in the solo mobile application and it’s very inconvenient to search in Google and other sources. this can be done, but the writing process becomes slow. it turns out I need to read a book. But thank you anyway .
