Answer 1

5. function prototype(s) which are correct.

void setValue(int &value); ----- reference parameter with name is allowed

void setValue(int &); ----- reference parameter without name is allowed

void setValue(int value, int max=100); ---- default value(max = 100) is allowed

But void setValue(int ++value); is not allowed as incrementation operation is not allowed in the parameter of the function.

6. Calling an overloaded function can result in multiple values being returned to the caller. False

The return type of the overloading function cannot alone implement overloading. There should be difference in the type , number or order of arguments.

7.A void function has no return value(s), but can have many parameter(s). Otherwise a function can return one value(s).

8. Only variables can be passed as reference.----- False

function pointers can also be passed as reference.

9.When writing a C++ program you must be careful to arrange all the functions in the order in which they are called.---True

The functions which are being called should be written earlier to the calling functions.
