C# null coalescing operator equivalent for c++

Question

Is there a C++ equivalent for C# null coalescing operator? I am doing too many null checks in my code. So was looking for a way to reduce the amount of null code.

Answer 1

There isn't a way to do this by default in C++, but you could write one:

in C# the ?? operator is defined as

a ?? b === (a != null ? a : b)

So, the C++ method would look like

Coalesce(a, b) // put your own types in, or make a template
{
    return a != null ? a : b;
}
