In this example, since f( ) is defined prior to its use in main( ), no separate prototype is required. While it is possible for a function s definition to serve as its prototype in small programs, it is seldom possible in large ones especially when several files are used. The programs in this book include a separate prototype for each function because that is the way C/C++ code is normally written in practice. The only function that does not require a prototype is main( ), since it is the first function called when your program begins. Because of the need for compatibility with the original version of C, there is a small but important difference between how C and C++ handle the prototyping of a function that has no parameters. In C++, an empty parameter list is simply indicated in the prototype by the absence of any parameters. For example,

Bridges need to be analyzed in both open and closed positions, and for positions in between. AASHTO movable bridge speci cations specify that the seismic load used for the open position may be reduced by 50 percent if the bridge is in that position for less than 10 percent of time. Counterweights on bascule bridges represent large seismic inertias. The effect of the large mass on the girders should be explored. When the span is raised, the span drive braking machinery becomes effective. Seismic acceleration forces on brakes need to be investigated. Several methods of seismic retro t are outlined for bearings and expansion joints within the FHWA Retro t Manual. Primarily, the bearings, joint restrainers, and minimum seat widths for seismic Zone 2 criteria retro t need to be addressed. Because of stringent operational and mechanical tolerance requirements, movable bridges need to be evaluated not only for stress, but more importantly for displacements. Ef cient functioning of the expansion bearings therefore is important. In bascule bridges, there are heavy counterweights that signi cantly affect the seismic behavior of the long structure.

Some cameras have an external button to set white balance. Refer to your camera manual for detailed instructions on setting white balance for your camera.

A recurrent basal cell carcinoma after so many years would be unusual. A new primary basal cell carcinoma may happen to arise coincidentally in the same area. None of the specific shape designations given to vessels are pathonomonic of any specific pathology. Inter-observer agreement on the exact shape of blood vessels within a given lesion might vary with the personal experience of the individual. Polarizing instrumentation, ultrasound gel/hand cleaning gel, and minimal pressure should be applied to better visualize small vessels.

objective, traffic-conditioning functions at the edge of the network are necessary to ensure that the incoming rate is always below the configured outgoing rate. The recommended DSCP value for the EF PHB is 101110. The EF PHB can be implemented in network nodes in a number of different ways. For example, the EF PHB could be implemented by a priority queue. Such a mechanism could enable the unlimited preemption of other traffic such that EF traffic always gets first access to outgoing bandwidth. This approach could, however, lead to unacceptably low performance for non-EF traffic. Therefore, it is important that the implementation of EF in a given node is designed such that EF traffic does not inflict enormous damage to other traffic. One way to do this would be to police the rate of incoming EF traffic through a token bucket limiter. Another way to implement the EF PHB would be through the use of a weighted round-robin output scheduler, where the share of the output bandwidth allocated to EF traffic is equal to some configured rate. That output rate should be greater than or equal to the rate expected for incoming EF traffic. Assured Forwarding (AF) AF PHB is defined in RFC 2597. Its objective is to provide a service that ensures that high-priority packets are forwarded with a greater degree of reliability than lower-priority packets. Normally, the traffic into a DiffServ network from a particular source should conform to a particular traffic profile. In particular, the rate of traffic should not exceed some pre-agreed maximum. In the event that it does, the source of the traffic runs the risk that the data will be lumped in with normal best-effort IP traffic and will be subject to the same delay and loss possibilities. In fact, in a DiffServ network, certain resources will be allocated to certain behavior aggregates, which means that a smaller share is allocated to standard best-effort traffic. Thus, receiving best-effort service in a DiffServ network could be worse than receiving best-effort service in a non-DiffServ network. A given subscriber to a DiffServ network might want the latitude to occasionally exceed the requirements of a given traffic profile without being too harshly punished. AF PHB offers this possibility. AF PHB is a means for a provider to offer different levels of forwarding assurances for packets received from a customer. AF PHB enables packets to be marked with different AF classes and, within each class, to be marked with different drop precedence values. Within a router, resources are allocated according to the different AF classes. If the resources allocated to a given class become congested, then packets must be dropped. The packets to be dropped are those with higher drop precedence values. From a customer s point of view, this offers the possibility of saying something like, Please don t drop my packets, but if you have

This program produces the following output:

PacketHeader is a good choice for a struct because it contains only a small amount of data and does not use inheritance or even contain methods. As a structure, PacketHeader does not incur the additional overhead of a reference, as a class would. Thus, any type of transaction record can use PacketHeader without affecting its efficiency. As a point of interest, C++ also has structures and uses the struct keyword. However, C# and C++ structures are not the same. In C++, struct defines a class type. Thus, in C++, struct and class are nearly equivalent. (The difference has to do with the default access of their members, which is private for class and public for struct.) In C#, a struct defines a value type, and a class defines a reference type.

In the preceding programs, the following line was used to declare an object of type Building:
