parameter passing technique

Question

from below list of parameter passing techniques, which parameter passing technique we can implement in c?

1) call by value

2) call by refference

3) call by value result

4) call by name

5) call by text

6) call by need

Comments

We can implement call by value and simulate call by reference by using call by pointer technique in C. Rest of them are not supported.

Call by value is by default parameter passing technique in c. And we can support call by reference using pointers and address passing(by using &).
