The goto-less goto!
by Robert S Sharp
I'm a C# programmer. I try to avoid goto at all costs, and generally I try to avoid throwing exceptions for the purpose of controlling the flow of execution. I've always been of the opinion that exceptions are for exceptional situations and indicate errors rather than expected conditions.I...
The goto-less goto!
by Philippe Mori
If the number of conditions is relatively small, the following code would made sense: bool bFailed = true; if (!condition1_fails) { if(!condition2_fails) { ... if(!conditionN_fails) { bFailed=false; ...
The goto-less goto!
by Philippe Mori
Alternative 2 can be enhanced by returning a booleen value if we want to code something similar to the original example. A (early) return value of false would indicate a failure which could then be handle by checking the function result.if (!DoAllActions()){ ...
The goto-less goto!
by guilherme heringer
In C#, you can always use try..finally to add some finalization code.Just write:bool bFailed = true; try{ if(condition1_fails) return; ... if(condition2_fails) return; ... ... if(conditionN_fails) ...
The goto-less goto!
by jsc42
It is much easier (and cleaner) to test for success than to test for failure.Viz:if ( condition1 // Note: Test for success, not for fail && condition2 // Will be short-circuited if condition1 fails && condition3 // Will be short-circuited if condition1 or condition 2...
The goto-less goto!
by rxantos
For Cbool bFailed = true;// foreverfor(;;) { // do something here. if(condition1) { // exit the loop (goto) break; } // do something here. // .... // In case you want to goto to the top instead of exit. if(condition2) { // jump to top of the...
The goto-less goto!
by abridges
Alternate 8, why not just do this:bool bFailed = true;// In case of an exception.try{ // while bFailed while (bFailed) { // do something here. if (condition1) { // exit the loop (goto) bFalse = false; ...
The goto-less goto!
by sergiogarcianinja
As this piece of code is normally a function, should be more readable if all of it is put inside a function returning a bool, indicating success or failure.The cleanup function could be only resource deallocation, not a function at all. If it is intended to use with C++ or C#, a try..finally...
The goto-less goto!
by Jörgen Sigvardsson
Usually, gotos are used to clean up resources when exiting a function. I would recommend using the RAII[^] idiom. It also works works well in the presence of exceptions.For C# I would use IDisposable/using. If that's not possible, I'd use a finally clause to clean up.Everything else...
The goto-less goto!
by Wolfgang_Baron
If you really have to put everything into a single function and want to keep the code analyzable and maybe want to be able put some common code at the end, you can always use a success variable. The code does not slow down, as the compiler optimizes the sequenced if-conditions away and produces...
The goto-less goto!
by Member 4694807
My favorite is a variant of alternative 2.{ ... DoInit(); status=DoAllActions(); DoCleanup(status); ...}int DoAllActions(){ if (condition1_fails) return status1; ... if (condition2_fails) return status2; ... if(conditionN_fails) ...
The goto-less goto!
by Jose David Pujo
Here goes my alternate.I am a C++ programmer. My goal is always to try to make code short and simple.bool bFailed=false;if (!bFailed) bFailed= condition1_fails;if (!bFailed) bFailed= condition2_fails;if (!bFailed) bFailed= condition3_fails;if (bFailed) DoFailedCleanup();else {...
The goto-less goto!
by testy_proconsul
bool bFailed = false; bFailed |= bFailed ? true : condition1; bFailed |= bFailed ? true : condition2; bFailed |= bFailed ? true : condition3; if( !bFailed ) { PerformActionOnAllSuccess(); ...
The goto-less goto!
by CashCow2
The correct way to do this in C++ is to invoke some form of RAII whereby the failure logic happens automatically in an object's destructor.class CleanupObject{public: CleanupObject() : successState( false ) { } void completedOk() { successState = false;...
