// Question 4:
// Declare an integer variable named "variables with an initial value of 10.
// Write a method named "SetToOne" that takes one out parameter.
// The method should set the out parameter to 1.
// Call the method SetToOne passing variables in the btnQ4 click method.
// Display the variable variables in the lblQ4.
private void btn04_Click(object sender, EventArgs e)

Modify the Percentages application whose main() method holds two double variables. Assign values to the variables.
Pass both variables to a method named computePercent() that displays the two values and the value of the first number as a percentage of the second one. For example, if the numbers are 2.0 and 5.0, the method should display a statement similar to “2.0 is 40.0 percent of 5.0.”
Then call the method a second time, passing the values in reverse order.
For testing use the values 2.0 and 5.0.
An example of the program is shown below:
2.0 is 40.0 percent of 5.0 5.0 is 250.0 percent of 2.0
