vector find index
I don't think you can capture the index, but you can use an outer variable to do the indexing, capturing it into the lambda: int j = 0; std::for_each(data.begin(), ... ,The code you quote in the comment: [code]vector<int>::iterator indx=lower_bound(v.begin(),v.end(), num); int pos=indx-v.begin(); if(indx == v.end() || *indx! ,find example #include <iostream> // std::cout #include <algorithm> // std::find #include <vector> // std::vector int main () // using std::find with array and pointer: ... ,You could use std::numeric_limits<size_t>::max() for elements that was not found. It is a valid value, but it is impossible to create container with such max index. , I am trying to get the index of an element in a vector of strings , to use it as an index in another vector of int type, is this possible ? Example: vector ..., You can keep the iterator returned by the find function like so: std::vector<string>::iterator iter = std::find(nodesRefCollection.begin(), ..., ,In this post, we will see how to find index of the first occurrence of a given element in vector in C++. The simplest solution is to use the std::find algorithm defined ... , In this article we will discuss different techniques to get an element from vector by index or position.
