• Which of the function call is call by value for the following function prototype? float add(int);

• add(&x);

• add(x);

• add(int x);

• add(*x);

[jäqüär β$ɨţ-5]

add(x) would be the correct answer I believe.

add(*x) - when you declare a function as call by reference.

add(&x) - when you call by reference

add (int x) - when you declare a function as call by value.

[hifzah]

add(x);

[hifzah]

add(x);
