Return iterator of a sublist c++

Question

We have a list

std::list<int> list;

// fill part of the list with 5
list.push_back(5);
list.push_back(5);
list.push_back(5);

// fill part of the list with 10
list.push_back(10);
list.push_back(10);
list.push_back(10);

// iterator that starts with 5
std::list<int>::iterator iterFiveBegin = list.begin();


//
std::list<int>::iterator iterEnd = list.end();

How can I get the iterator std::list<int>::iterator iterTenBegin of the list where it starts with "10"?

Answer 1

Firstly, don't use variable name list, try intList instead.

You may use std::find

std::list<int>::iterator it = std::find (intList.begin(), intList.end(), 10);

Per std::find documentation:

std::find
Return value
Iterator to the first element satisfying the condition or last if no such element is found.
