Parameter Passing Techniques in C/C++

Question

There are different parameter passing techniques like - Call By Value, Call By Reference, Call By Value Result, Call By Name, Call By Text and Call By Need in Programming Languages.

I have seen implementations of Call By Value and Call By Reference in C/C++; but the other techniques were taught only with simple plain examples, where we are given that this example uses say "Call By Value Result" and so answer accordingly. I was wondering whether the other techniques have ever been implemented in C/C++ or any other languages or were they just theoretical?

C provided and still provides pass by value only.

In C++ it's only by value or by reference. The other techniques can be simulated using existing C++ language constructs - specially crafted conversion operators and constructors.
