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 { 
  PerformActionOnAllSuccess(); 
  DoNormalCleanup();
} 


Pros



  • Short and simple to read
  • You can set debug breakpoints in any condition to test return values
  • No functions / exceptions needed

Good approach, but I think that it doesn't work:

bFailed = condition1_fails = condition2_fails = condition3_fails;

Doesnt's shortcircuit and maybe you get a Syntax error
Better:

bFailed = condition1_fails || condition2_fails || condition3_fails;
