Question

what does call by value and call by reference mean?​

Answer 1

Functions can be invoked in two ways: Call by Value or Call by Reference. These two ways are generally differentiated by the type of values passed to them as parameters. The parameters passed to function are called actual parameters whereas the parameters received by function are called formal parameters.

Answer 2

Call by value is directly calling the value from the function whereas call by reference is calling a value by referring a function to another.
