Notice that StrMod takes one string parameter and returns a string. Next, in DelegateTest, three static methods are declared, each with a single parameter of type string and a return type of string. Thus, they match the StrMod delegate. These methods perform some type of string modification. Notice that ReplaceSpaces( ) uses one of string s methods, called Replace( ), to replace spaces with hyphens. In Main( ), a StrMod reference called strOp is created and assigned a reference to ReplaceSpaces( ). Pay close attention to this line:

There is a special type of namespace, called an unnamed namespace, that allows you to create identifiers that are unique within a file. It has this general form: namespace { // declarations } Unnamed namespaces allow you to establish unique identifiers that are known only within the scope of a single file. That is, within the file that contains the unnamed namespace, the members of that namespace may be used directly, without qualification. But outside the file, the identifiers are unknown.

Earlier you learned that it is legal to compare the value of one pointer to that of another. However, in order for a pointer comparison to be meaningful, the two pointers must have some relationship to each other. The most common way such a relationship is established is when both pointers point to elements of the same array. For example, given two pointers, A and B, that both point into the same array, if A is less than B then A points to an element at a smaller index than the element pointed to by B. Such comparisons are especially useful for determining boundary conditions. The following program demonstrates a pointer comparison. The program creates two pointer variables. One, called start, initially points to the beginning of an array, and the other, called end, points to the end of the array. As the user enters numbers, the

Deciding what you should migrate to the cloud really comes down to figuring out what you want out of the cloud. That is, are you looking to store data on someone else s servers If that s the case, it s simply a matter of deciding which data you want to send (and pay for) and what data doesn t need to be sent. If you are using the cloud for SaaS or PaaS, you have to look at which applications are most appropriate for maintenance on the cloud. It will obviously differ from organization to organization, but you likely won t move your key mission-critical tasks to the cloud. For instance, a company that develops software for healthcare providers is going to have different needs than a financial advisor, for Different companies will need to send instance. But even within the same different applications to the cloud. industry, different organizations will get Even companies in the same industry different things out of the cloud. will perform different work on the cloud.

To create an inserter function for an object of type three_d, you must overload the << operator. Here is one way to do this:

is well de ned. Look at Fig. 6.22 for the graph. It can be shown that 1 d Cot 1 x = . dx 1 + x2 De ne Sec x to be the function sec x restricted to the set [0, /2) ( /2, ] (Fig. 6.23). Then Sec x is one-to-one. For these values of the variable x, the cosine function takes all values in the interval [ 1, 1] except for 0. Passing to the reciprocal, we see that secant takes all values greater than or equal to 1 and all values less than or equal to 1. The inverse function is Sec 1 : ( , 1] [1, ) [0, /2) ( /2, ]

Good forecasts must be consistent with historical performance and the current industry outlook. Look at historical numbers in relationship to others and use these ratios, particularly the operating ratios, to make your projections. All forecasts are estimates and approximations. Spend the time thinking and developing your ideas about the big picture, not the third decimal place. If the forecast looks too good to be true, it probably is. Re-examine your assumptions.
