C++ Vector end()

This function returns an iterator referring to the past-last-element in the vector container.

Syntax

Consider a vector v. Syntax would be:

iterator it=v.end()

Parameter

It does not contain any parameter.

Return value

It returns an iterator following the last element.

Example 1

Let's see a simple example.

#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<int> v{10,20,20,40};
vector<int>::iterator it;
for(it=v.begin();it!=v.end();it++)
cout<<*it<<" ";
return 0;
}

Output:

10 20 20 40

In this example, elements of the vector have been iterated using begin() and end() function.

Example 2

Let's see another simple example.

#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<string> v{"Welcome","to","javaTpoint"};
vector<string>::iterator it;
for(it=v.begin();it!=v.end();it++)
cout<<*it<<" ";
return 0;
}

Output:

Welcome to javaTpoint

In this example, strings of vector have been iterated using begin() and end() function.
