Output Iterators in C++ programming

C++Server Side ProgrammingProgramming

In this tutorial, we will be discussing a program to understand output iterators in C++.

Output iterators are a part of the major five iterators. They function opposite of the input iterators in a way that they can be assigned values but can’t be accessed to fetch values.

Example

 Live Demo

#include<iostream>
#include<vector>
using namespace std;
int main(){
   vector<int>v1 = {1, 2, 3, 4, 5};
   //declaring iterator
   vector<int>::iterator i1;
   for (i1=v1.begin();i1!=v1.end();++i1){
      *i1 = 1;
   }
   return 0;
}

Output

No output, because we cannot access values of output operators
