Before going into the mechanics of using ref and out, it is useful to understand why you might want to pass a value type by reference. In general, there are two reasons: to allow a method to alter the contents of its arguments or to allow a method to return more than one value. Let s look at each reason in detail. Often, you will want a method to be able to operate on the actual arguments that are passed to it. The quintessential example of this is a swap method that exchanges the values of its two arguments. Since value types are passed by value, it is not possible to write such a method that swaps the value of two ints, for example, using C# s default call-by-value parameterpassing mechanism. The ref modifier solves this problem. As you know, a return statement enables a method to return a value to its caller. However, a method can return only one value each time it is called. What if you need to return two or more pieces of information For example, what if you want to create a method that computes the area of a rectangle and also determines if that rectangle is a square To do this requires that two pieces of information be returned: the area and a value indicating square-ness. This method cannot be written using only a single return value. The out modifier solves this problem.

The preliminary work done by the feasibility committee combined with management s reaction to the financial analysis enable the planning committee to identify the parameters of the Citrix project. In particular, the committee must select the applications to be run via Citrix along with expectations for stability and for upgrades during the implementation process. Adding a new application, for example, requires extensive testing as well as the creation of a new server image. What s known as scope creep is inevitable, and guidelines need to be established for an approval process when requests for additional applications or features are made. Allowances must also be made for delays caused by these changes.

is used, it obtains the number of arrays stored in network_nodes, which is four in this case. To obtain the length of any individual array in the jagged array, you will use an expression such as this:

wo types of processes commonly involve energy changes chemical reactions and the dissolving process. Heat of reaction is the overall energy absorbed or released during a chemical reaction. Heat of solution is the overall energy absorbed or released during the solution process. Both are the difference between the energy absorbed to break bonds and the energy released when new bonds are formed. In this activity, you will investigate two examples of heat of solution and one example of heat of reaction. The first example of heat of solution is the heat transferred when concentrated sulfuric acid (H2SO4 ) is added to water. The second is the dissolving of the ionic compound ammonium chloride (NH4Cl) in water.
