Call by value in programming means that a copy of variable value is pased from function calling part to function definition part. Call by reference means that an address of variables are passed from calling part to function definition. arrow_forward Step 2 Call by reference is used to avoid extra memory usage because in call by reference same variables addresses are passed. Any changes made will reflect back. So it doesn't require extra variable to hold data. Call by value in programming is used where memory storage is not concern. Scenario in which actual value must not be disturbed then in these type of cases, call by value is used. We can't use only one because user requirement changes. Sometimes user tella actual data should be preserved and he/she want any data processing, in such scenario programmers use call by value. Some users only want calculated result. In such cases, programmers use call by reference to preserve memory usage. So it is totally dependent on user…
