C++ Builder implements all of these functions and includes several of its own. Many of the functions added by C++ Builder are long double versions of the standard functions. These C++ Builder specific functions are also discussed here. Remember, however, that they are not defined by C89 or C++. All the math functions require the header <math.h> to be included in any program using them. In addition to declaring the math functions, this header defines three macros called EDOM, ERANGE, and HUGE_VAL. If an argument to a math function is not in the domain for which it is defined, an implementation-defined value is returned and the global errno is set equal to EDOM. If a routine produces a result that is too large to be represented, an overflow happens. This causes the routine to return HUGE_VAL and errno is set to ERANGE, indicating a range error. (If the function returns a long double, then it returns _LHUGE_VAL.) If an underflow happens, the routine returns 0 and sets errno to ERANGE.

Tables 4 . 1 0 to 4.12 show the input tables and the result. Only small input and result tables have been used so that y o u can understand more clearly the process to derive the result. It does not take large tables to depict the conceptual evaluation process well. The conceptual evaluation process is a sequence o f operations as indicated in Figure 4 . 2 . This process is conceptual rather than actual because most SQL compilers can produce the same output using many shortcuts. Because the shortcuts are system specific, rather mathe matical, and performance oriented, w e will not review them. The conceptual evaluation process provides a foundation for understanding the meaning o f S Q L statements that is independent o f system and performance issues. The remainder o f this section applies the conceptual evaluation process to Example 4.22. 1. The first step in the conceptual process combines the tables in the F R O M clause with the cross product and join operators. In Example 4.22, a cross product operation is necessary because two tables are listed. A j o i n operation is not necessary because the I N N E R JOIN keyword does not appear in the FROM statement. Recall that the cross product operator shows all possible rows b y combining two tables. The resulting table contains the product o f the number o f rows and the sum o f the columns. In this case, the cross product contains 35 rows (5 X 7) and 7 columns (3 + 4 ) . Table 4.13 shows a partial result. A s an exercise, y o u are encouraged to derive the entire result. A s a notational shortcut here, the table name (abbreviated as E and O) is prefixed before the column name for OfferNo. 2. The second step uses a restriction operation to retrieve rows that satisfy the conditions in the W H E R E clause from the result o f step 1. We have four conditions: a join condition o n OfferNo, a condition o n CourseNo, a condition o n OffYear, and a condition o n OffTerm. N o t e that the condition o n CourseNo includes the wildcard character (*). A n y course

The average-value-of-a-fction problems so far have had pretty tame-looking hctions. This next problem will illustrate how to apply the average value of a fhction to some more complex hctions.

The main limitation of clientless mode is that it doesn t support non-web-based applications. Thin client mode was created to add support for some, but not all, of these applications. In thin client mode, the SSL gateway acts as a TCP proxy, proxying TCP connections from the user to resources beyond the gateway. Cisco supports three thin client implementations: port forwarding, plug-ins, and smart tunnels. All require that a web browser and Java 1.5 or later be installed on the user s desktop to operate correctly. With the thin client function, the user logs into the SSL gateway via clientless mode and then starts the thin client function; optionally you can have the thin client process start up automatically once the user logs in. Some modification of the supported applications may be necessary to successfully protect them across the SSL tunnel. Currently Cisco does not support all non-web-based applications using the thin client mode. Some common supported applications include telnet, SSH, e-mail, Citrix, VNC, Windows Terminal Services, and many others.

Because the sequence obtained when webAddrs is executed is a list of groups, you will need to use two foreach loops to access the members of each group. The outer loop obtains each group. The inner loop enumerates the members within the group. The iteration variable of the outer foreach loop must be an IGrouping instance compatible with the key and element type. In the example both the keys and elements are string. Therefore, the type of the sites iteration variable of the outer loop is IGrouping<string, string>. The type of the iteration variable of the inner loop is string. For brevity, the example implicitly declares these variables, but they could have been explicitly declared as shown here:
