Is there an equivalent of Pythons `pass` in c++ std11?

A null statement (just Semicolon), or empty brackets should work for you

For example Pythons

while some_condition():    # presumably one that eventually turns false
    pass

Could translate to the following C++

while (/* some condition */)
    ;

Or

while (/* some condition */) {}

Perhaps for the ternary operator case, you could do:

x > y ? do_something() : true;

No. You dont have pass or equivalent keyword. But you can write equivalent code without any such keyword.

def f():
   pass

becomes

void f() {}

and

 class C:
     pass

becomes

 class C {};

In different context, different syntax could be useful. For example,

 class MyError(Exception):
        pass

becomes

class MyError : public std::exception
{
      using std::exception::exception; //inherits constructor!
};

As you can see, in this context, youve to write using to inherits constructors from the base class. In Python, pass does the similar thing, in similar context.

Hope that helps.

As has been stated in the comments, this is not supported because it makes no sense. The conditional operator is designed to evaluate to one of two operands. Two. Not one.

It is not okay to abuse the operator to perform some conditional action in only one of those cases. In fact, it is best that neither operand have any side-effects whatsoever. This is not a do something construct, but a give me one of two things construct.

In this regard, if Python were to support what you say it supports, then it would be broken where C++ is not. As it happens, Python doesnt actually support it either, after all.

Write an if statement, instead:

if (x > y) {
   do_something();
}
else {
   /* Unimplemented at the moment */
}
