海外TECH	DEV Community	The big STL Algorithms tutorial: comparison operations	https://dev.to/sandordargo/the-big-stl-algorithms-tutorial-comparison-operations-2bfh	The big STL Algorithms tutorial comparison operationsIn this next part of the big STL algorithm tutorial we are going to talk about three comparison operations equallexicographical comparelexicographical compare three way equalstd equal compares two ranges to each other and returns true if the ranges are equal false otherwise There are mainly two different overloads of std equal but as each of them can be constexpr since C and all of them can be parallelized by passing an ExecutionPolicy as a th parameter since C and a binary predicate as the last parameter in order to replace the default operator there are many different overloads So what are the different overloads The first one accepts three iterators The first two iterators define the first range by its first and last element and the third iterator is to show where the second range starts In this case the caller must make sure that after the third iterator there are least as many elements as there are in the range defined by the first two iterators Otherwise it s undefined behaviour The other overload takes four iterators where the second pair fully defines the second range used in a comparison and it s available since C It seems like a nice idea first I was thinking that I might check whether the second range is the same size as the first one But it s not the case On the other hand let s say you have a larger range that you want to pass in the second position With the parameter version std equal will check if the first range is the subrange of the second one which might mean equality With the full version where you define both ranges by their beginning and end you really check for the equality of two ranges Let s see it in an example include lt algorithm gt include lt iostream gt include lt vector gt int main std vector nums std vector fewerNums std cout lt lt std boolalpha std cout lt lt std equal nums begin nums end fewerNums begin lt lt n std cout lt lt std equal fewerNums begin fewerNums end nums begin lt lt n std cout lt lt std equal nums begin nums end fewerNums begin fewerNums end lt lt n std cout lt lt std equal fewerNums begin fewerNums end nums begin nums end lt lt n falsetruefalsefalse lexicographical comparestd lexicographical compare checks whether the first range is lexicographically less smaller than the second range using the operator lt unless the caller passes in a different comparison function Both of the two ranges are defined by their begin and end iterators and as mentioned you can pass in custom comparator and of course an execution policy But what is lexicographical comparison A lexicographical comparison is basically an alphabetical ordering where two ranges are compared sequentially element by element if there is any mismatch that defines the resultif one range is a subrange of the other the shorter range is less than the otheran empty range is always less than the otherThe returned value is true if the first range is less than the other otherwise we get false include lt algorithm gt include lt iostream gt include lt vector gt int main std vector nums std vector fewerNums std vector lt int gt empty std cout lt lt std boolalpha std cout lt lt std lexicographical compare nums begin nums end fewerNums begin fewerNums end lt lt n std cout lt lt std lexicographical compare fewerNums begin fewerNums end nums begin nums end lt lt n std cout lt lt std lexicographical compare nums begin nums end nums begin nums end lt lt n std cout lt lt std lexicographical compare empty begin empty end nums begin nums end lt lt n std cout lt lt std lexicographical compare empty begin empty end empty begin empty end lt lt n falsetruefalsetruefalse lexicographical compare three wayIf you feel that it s impractical to get a true false result for a comparison whereas there could be outcomes less greater or equal you should use std lexicographical compare three way given that you work with a compiler supporting C By default it returns one of the constants of std strong ordering but it can also return std weak ordering or std partial ordering depending on the return type of the custom comparator that you can also define The default comparator is std compare three way include lt algorithm gt include lt iostream gt include lt vector gt std ostream amp operator lt lt std ostream amp out std strong ordering ordering if ordering std strong ordering less out lt lt less than else if ordering std strong ordering equal out lt lt equal else if ordering std strong ordering greater out lt lt greater than return out int main std vector nums std vector fewerNums std vector lt int gt empty std cout lt lt std boolalpha std cout lt lt std lexicographical compare three way nums begin nums end fewerNums begin fewerNums end lt lt n std cout lt lt std lexicographical compare three way fewerNums begin fewerNums end nums begin nums end lt lt n std cout lt lt std lexicographical compare three way nums begin nums end nums begin nums end lt lt n std cout lt lt std lexicographical compare three way empty begin empty end nums begin nums end lt lt n std cout lt lt std lexicographical compare three way empty begin empty end empty begin empty end lt lt n As you can see the possible outcomes are not printable you have to convert them manually into something that can be streamed to the output stream When you think about non equal results they are always relative to the first range The first is greater or less than the second ConclusionThis time we learned about comparisons algorithms They help us to compare ranges of elements With std equal we can compare if two ranges are equal or not and with std lexicographical compare or std lexicographical compare three way we can perform lexicographical comparison Next time we will discover
