C++ indexed set
WebSearches the container for an element equivalent to val and returns an iterator to it if found, otherwise it returns an iterator to set::end. Two elements of a set are considered equivalent if the container's comparison object returns false reflexively (i.e., no matter the order in which the elements are passed as arguments). Parameters val Value to be searched for. WebReturns an iterator pointing to the first element in the container which is not considered to go before val (i.e., either it is equivalent or goes after). The function uses its internal comparison object to determine this, returning an iterator to the first element for which key_comp(element,val) would return false. If the set class is instantiated with the default …
