Tom qab ntawd, ib tug kuj yuav nug, std:: ua haujlwm li cas?
std:: pib() yuav rov qab ib qho iterator(pointer) rau thawj lub caij hauv array peb dhau nws. Qhov twg std:: kawg() yuav rov qab ib qho iterator(pointer) mus rau ib qho dhau los ntawm cov khoom kawg hauv cov array peb dhau nws. Yog li peb tuaj yeem hu rau xaiv ua haujlwm los ntawm kev hla nws pib() thiab xaus() zoo li ntawd.
Kuj Paub, yog std:: txheeb ruaj khov? Yog lawm, std:: lis ::kev yog guaranteed yuav ruaj khov . Raws li "C++ Programming Language" (Stroustrup p470), yog, stl :: lis ::kev yog ruaj khov.
Qhov thib ob, dab tsi algorithm ua std:: txheeb siv?
Siv std::sort (los yog std::stable_sort) Nws feem ntau yog ib qho kev siv tau zoo ntawm Introsort algorithm uas pib nrog kev ceev thiab hloov mus rau heapsort thaum lub recursion mus tob heev. The std::sort algorithm tsis tuav cov txheeb ze ntawm cov khoom sib npaug.
