Note that even though the for-loop above causes the switch-statement to be executed 1000000 times, the really expensive calculations to update the value of x are only performed (at most) once. IsCalculationValid = true // remember we already did the calculationÄoReallyExpensiveCalculationOnce(x, isCalculationValid) X += 6 // pretend this operation is really slow/expensive For trivial calculations that's fine, but what if your calculations were really computationally expensive, so much so that you want to avoid performing them more than one time whenever possible? For that you can use a technique called memoization, which is really just storing the result of the calculation in a variable, plus setting a flag the first time you perform the calculation so that you can remember not to do it the next time: void doReallyExpensiveCalculationOnce(int & x, bool & isCalculationValid) data analysis performed without software support tends to focus on only a. you only had to write the code inside addSix(int) in one location), but it does mean that the code inside addSix(int) is executed each time the switch-statement is executed. MacSHAPAs relation to other ESDA software tools is indicated throughout the. avoids the need to write redundant code (i.e. Or perhaps you want the more traditional pattern, where every case has a break at the end and you only want to execute one of the cases. Unlike other software on the market where you could open up a text file and start coding, in HyperRESEARCH you link these sources to one or more cases first. The first question is: is your code supposed to execute both cases, one after another? If so, you can do that using the switch statement's "fall through" feature, which is to say, by omitting the break statement at the end of the first case, you can let the program's execution "fall through" to the next case immediately after the first case executes, like this: int x = 5 The code list file is created on your disk in plain text format. Enter a name for the exported list, then export the file. From the 'Edit Codes' menu at the top of the Code Book window, choose 'Export List'. Powerful: Advanced features give you complete access to and control over your data. Recall your codes by name, or select them based on proximity to other codes. The techniques described below try to address both of those concerns. If the Code Book window is not already visible, choose Codes > Code Book to show it. Select any chunk of text (from a single character to an entire file) and apply any number of code names to the chunk. I'm going to assume that your motivation for this question is either that you want to avoid writing redundant/duplicate code, or that you want to minimize CPU cycles by not performing the same mathematical operation more than once.
