The compiler can do inlining when creating the table having f1, f2, f3 setting x directly to 6,9,8Д«ut if you wrote the functions, and rolled your own jump table, f1,f2,f3 could be anywhere, but the compiler will know to put them close to the switch creating much better code locality than you could. You could have something like the following: int f1() To further elaborate on Jerry's answer and others However, don't get lost by just looking at overall algorithmic complexity: it hides important factors.

In the particular case of switch statements, since the compiler has full information, it can generate a perfect hash function which means O(1) lookup. Briefly, if by 'dictionary' you mean a balanced binary tree, then it is O(log n) and a hash table depends on its hash function and collision strategy. You should look into studying data structures to get a handle on the different complexity requirements imposed by them. The compiler is free to choose the lookup method for each switch statement, and there is no guarantee you'll get one particular implementation however, compiler options such as optimize-for-speed and optimize-for-size should be taken into account.

Saying that some code 'uses a jump table' doesn't imply by itself that you have O(1) lookup. That mapping is where terms like 'dictionary' and 'hash table' come in, and those techniques can be used independently of a jump table. These 'limited jump tables' are a different pattern, which is only taking advantage of a jump table's well-studied efficiency, and are common when each 'action' is independent of the others.ДЄctual implementations of jump tables take different forms, mostly differing in how the key to index mapping is done.

However, the full capability of a jump table is often not required, such as when every case would have a break statement. (How to implement jump tables efficiently has been studied much more for integral types than for the general case.) A classic example is Duff's Device. Only a limited form is provided (can only switch on integral types) to make implementations easier and faster in this common case.

(Wikipedia's article on branch tables is related.)ДЄ switch statement is how to write jump tables in C/C++. In particular, this control flow is not the same as a function call. Goto, continue, and break are similar, except they always transfer to a specific location instead of one possibility from many. For more information about downloading this sample report and others, see Report Builder and Report Designer sample reports.A jump table is an abstract structure used to transfer control to another location. We can't directly implement match scales dynamically. You could reference the videos to have a try. Otherwise, you could put the data into one chart and create a double Y-axis to show.

For more information, see Multiple Series on a Chart.ДЄn example of this chart is available as a sample report. If so, you could set a same fixed scale in the Y-axis of two visuals. In situations where there are more than two series to be compared, consider a different approach for comparing and displaying multiple series in a chart. If we show Revenue on the primary axis, and Tax on the secondary axis, we can display each series on its own y-axis with its own scale of values. However, when both series are plotted on the same y-axis, we cannot make a useful comparison because the scale of the y-axis is optimized for the largest values in the dataset. In this case, the 2008 time period is common to both value sets.

The secondary axis is useful when comparing two value sets with two distinct data ranges that share a common category.ДЇor example, suppose you have a chart that calculates Revenue vs. The paginated report chart has two axis types: primary and secondary.
