Expert Solution & Answer
Chapter 5, Problem 3FTE
Explanation of Solution
Given
//Line 1- Define a method timesTwo()
public static double timesTwo(double num)
{
//Line 2- Compute value
double result = num*2;
}
Methods:
- The methods could be used to break a complex program into small pieces.
- The “void” method simply executes a statements group and then terminates.
- A value returning method would return a value to statement that has called it.
- While calling a method, program would branch to that method.
- It would then execute statements in its body.
- The values that are sent into a method are termed as “arguments”.
- A “parameter” denotes a special variable that holds a value that is being passed into a method.
- The “passed by value” means that only copy of a value of argument is been passed into parameter variable...

Free Response Question:
28. Write a method that will return true if a randomly generated number between 1 and 10 is less than
or equal to 4.
public static boolean FortyPercentOrLess()
{
}
public static int cube(int num
{
return num
num
num;
}
What is the correct statement to pass value 8 to this method and assigns its return value to a variable named result?
O cube(8) = int result;
int result = cube(8)
O int result =
O int result = int cube(8);
Examine the following method header; then write an example call to the method. private void ResetValue(ref int value)
