It has always seemed counter-intuitive to me that in the <while> block of the <do...while> loop inner names can't be accessed... simplest example: bubble sort do { bool changes = false; // iterate thru all elements // if swapping anything, set changes = true } while (changes) ^ This will cause an error complaining about undefined identifier 'changes'. Yet it's more intuitive to code that way... bool changes; do { changes = false; //... } while (changes) ^ This will work fine It seems a little bit C-ish to explicitly define a variable just two lines above its initialization. Maybe this could be changed yet ? Or am I missing something ? | ||||||||||||||||||||||
