Question

Select all true statements about function parameters:
a function call can't modify the outside values (the callers values) of the parameters passed by reference to the
function if those parameters are qualified as const
pass by reference is useful to modify the outside value (callers value) of a parameter passed
a function call can modify the outside values (the callers values) of the parameters passed by value to the function
passing by value could be an expensive operation for a larger data type like strings
a function call can modify the outside values (the callers values) of the parameters passed by reference to the
function if those parameters are not qualified as const

True or False? A loop with no condition is equivalent to a loop with true as condition
(i.e., an infinite loop).
Hint: Please follow the re
True
False

Expert Solution

Step 1

Answer-A Option- D, B, E

Correct Answer-:

Passing by value could be an expensive operation for a larger data type like string because passing by value would require more memory as compared to reference.
Pass by reference is useful to modify the outside value of a parameter used as the referenced variable would behave as an alias to passed variable so any changes on alias would reflect on original passed value.
If parameters are not qualified as const then we can modify its value in the function.
