Question

What is the difference between cdecl and other calling conventions in terms of parameter passing?

a.

cdecl uses registers for passing the first two parameters, while other calling conventions pass parameters through the stack.

b.

cdecl passes parameters in the reverse order compared to other calling conventions.

c.

Other calling conventions allow functions to receive a dynamic number of parameters, while cdecl does not.

d.

Other calling conventions require the callee to restore the stack pointer after a function call, while cdecl does not.
