Question

The process of calling a method in such a way that the change in the formal arguments reflects on the actual parameter is known as:

Options

• Call by reference

• Call by value

• Call by method

• None

Answer 1

Call by reference

Explanation:

In a call by reference, the method receives the address (reference) of the actual parameter. This means that the formal parameters correspond to the exact memory location as the actual parameters, and any changes to the formal parameters directly impact the actual parameters.
