Is it better to use an array of pointers to members or a switch?
c++,optimization,switch-statement,function-pointers
It depends. Switch-case with multiple, not connected choices is effectively the same as big if-else - slow.

Curious thing is, that compilers can usually perform this kind of optimization automatically -...

The reason why some variable declarations are not allowed in a switch statement is: it is illegal for switch-based control flow to jump over a variable initialisation.

If multiple threads access an enum set concurrently, and at * least one of the threads modifies the set, it should be synchronized * externally. EnumSet is 'safe' only in the sense it will not throw any...
SQL subquery (stockin quantity runtime by sum up the stock in and stock out group by store and than subtract from stockin to stock out)
sql,switch-statement,subquery,inner-join,correlated-subquery
This (select ISNULL(Items_store.Item_ID,0) from Items_Store where ...) gets you the Item_ID from Items_Store. In case it is null (and I suppose this is never the case) you replace it by 0. In case no record can be found, you get NULL. Replace this by ISNULL((select Items_store.Item_ID from Items_Store where ...),...
Alternative for switch statement, drill down Table Views?
ios,uitableview,swift,xcode6,switch-statement
If you only have one detail controller, you don't need the switch statement at all. The best (most object oriented) way to do this would be to use custom objects to populate your cells. You could create a Sport object that would have two properties, name (NSString), and categories (NSArray)....
C++ switch statement odd output
You can test whether the result of cin >> decimal_number succeeded, like if(!(cin>>decimal_number)) throw std::runtime_error("Oops, not a decimal number!"); This is a bit too extreme, you can also validate the input: while(!(cin>>decimal_number)) { std::cout << "Not decimal, input again "; cin.clear(); cin.ignore(numeric_limits<streamsize>::max(), '\n'); } If you're not performing this kind...
stuck with switch in c project [duplicate]
You should add break: switch(month) { case 1:case 2: day_in_week++; if (day_in_week>7) day_in_week= day_in_week-7; break; case 3:case 4:case 5:case 6:case 7:case 8:case 9:case 10:case 11:case 12: day_in_week=day_in_week+2; if (day_in_week>7) day_in_week= day_in_week-7; break; } Also you should do it in next switch too. So, your code should looks like this: #include<stdio.h>...
some code in swich(..) {…} why set default if default mean to do nothing?
It's not necessary, it is a style thing. In the Google Java style guide it says: 4.8.4.3 The default case is present Each switch statement includes a default statement group, even if it contains no code. In the event you have a different case added that isn't handled in the...
Not counting right? [closed]
c#,loops,for-loop,switch-statement
The loop counts from 0 to four, but the switch checks the values 1 to 5. To include all 5 judges, change the for loop to: for (int count = 1; count <= 5; count++) ...
case operator on for operator
In a switch case block, once a case is satisfied, the control of the program will stop checking to see if each other case is true and will continue to execute each "action". For example: int i = 1; switch (i) { case 0: cout << "0"; //action 1 case...
Is there a way of checking more than one condition in Swift switch?
Repeated code? Good candidate for a local function: func statement3() { // ... lots of stuff here ... } switch char { case "+": statement 1; statement3() case "-": statement 2; statement3() default: statement3() } But if you really want to do statement3 in every case, then just take it...
