Find in vector c++

WebC++ Algorithm library Constrained algorithms Returns the first element in the range [first, last) that satisfies specific criteria: 1) find searches for an element equal to value 3) find_if searches for an element for which predicate pred returns true 5) find_if_not searches for an element for which predicate pred returns false Webfind () in C++ is a function used to search an element inside a specified range and returns the first occurrence of the element. find () in C++ takes first_element, last_element, and the value which we want to search is taken as arguments. If the value is not matched within the range then the find () function returns the last element after all ...
