Question

Assume you have written a method with the header void mymethod(num a, string b). Which of the following is a correct method call?

A) mymethod(5, "Hello")
B) mymethod("Hello", 5)
C) mymethod(5)
D) mymethod("Hello", "World")

Answer 1

The correct method call for the method header void mymethod(num a, string b) is A) mymethod(5, "Hello"), as it correctly provides a number as the first argument and a string as the second argument.

Step-by-step explanation:

If you have written a method with the header void mymethod(num a, string b), you need to pass arguments to it that match the types specified in the method signature when you call it. This means the first argument must be a number (num) and the second argument must be a string.

Looking at the options given:

1. A) mymethod(5, "Hello") - This matches the method signature exactly: a number followed by a string. Therefore, it is the correct method call.
2. B) mymethod("Hello", 5) - This does not match the signature because it passes a string first and a number second.
3. C) mymethod(5) - This is incorrect because it only provides one argument, but the method requires two.
4. D) mymethod("Hello", "World") - This is also incorrect because both arguments are strings and the first argument should be a number.

Based on the method signature, the correct method call is A) mymethod(5, "Hello").
