What is the main difference between call by value and call by reference?

Call by value and call by reference are the same, and both copy the actual value of the argument.
Call by value and call by reference are the same, and both copy the address of the argument.
Call by value copies the actual value of the argument, while call by reference copies the address of the argument. (correct)
Call by value copies the address of the argument, while call by reference copies the actual value of the argument.

In the call by value method, how do changes made to the parameter inside the function affect the argument?

Changes made to the parameter inside the function have no effect on the argument. (correct)
Changes made to the parameter inside the function may or may not have an effect on the argument.
Changes made to the parameter inside the function have an effect on the argument.
Changes made to the parameter inside the function always have an effect on the argument.

Which method of passing arguments to a function does C programming use by default?

Call by reference
Neither call by value nor call by reference
Both call by value and call by reference
Call by value (correct)
