C++ provides the functionality to find an element in the given range of elements in a vector. This is done by the find() function which basically returns an iterator to the first element in the range of vector elements [first, last) on comparing the elements equals to the val (value to ...

In this tutorial, we are going to learn how to find the index/position of an element in the vector. Along with its implementation in C++.

basic question is how to check a vector of structs to find an element that meets a condition in one of the struct members - using std::find_if with a predicate: // find the first struct in a vector with a double // member <= a given value #include <iostream> // std::cout #inc...
若要删除std::vector中的element,正规的方式该用find() generic algorithm,若find()找到了,会传回该iterator,若找不到,将传回vector.end()。这种写法远比用for loop干净很多。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : VectorFindAndErase.cpp ...

A Find Element Equal instruction is provided that compares data of multiple vectors for equality and provides an indication of equality, if equality exists. An index associated with the equal element is stored in a target vector register. Further, the same instruction, the Find Element Equal ...
I have a homework:if v is [1 2 3 4 5 4 3 2 1] and n is 3, it will find 4 5 and 4 because their sum of 13 is the largest of any 3 consecutive elements of v. The function returns summa, the sum as the first output argument and index, the index of the first el...
For each element of the result, the value of each bit is 1 if the corresponding elements ofadoes not equal to any element ofb. Otherwise, the value of each bit is 0. Table 1. Vector Find Any Element Not Equal dab vector bool charvector signed charvector signed char ...
