"Do nothing" in the else-part of the ternary operator?

Question

What's the standard line to add to the ternary operator in order to do nothing if the condition is not met?

Example:

int a = 0;
a > 10 ? a = 5 : /*do nothing*/;

Using a seems to do the trick, but I am wondering if there is a more generally accepted way.

Answer 1

That will do it:

a = a > 10 ? 5 : a;

or simply:

if (a > 10) a = 5;
