Lydia Thompson · Answer 1

d. int x = 7; displayValue (x);

Explanation:

Only option D is correct.

The declaration of the method displayValue () has a single int parameter.

When this method is called an int value is to passed as an argument terminated with a semi colon as given in option D.

Option A displayValue (int x); is wrong because it declaring x again at the method call Option B displayValue (x) has a syntax error "Missing semi colon" Option C void displayValue (x); is wrong, when calling a function its return type is not written.
