How to Remove an Element from Vector in C++?

Last Updated : 23 Jul, 2025

In this article, we will learn how to remove a given element from the vector in C++.

The most straightforward method to delete a particular element from a vector is to use the vector erase() method. Let's look at a simple example that shows how to use this function:

#include <bits/stdc++.h>
using namespace std;

int main() {
    vector<int> v = {1, 5, 7, 4};

    // Removing 7 from vector v
    v.erase(find(v.begin(), v.end(), 7));

    for (auto i : v)
        cout << i << " ";
    return 0;
}

Explanation: The vector erase() function removes the element using iterator not value, so iterator to the element to be removed is determined using find() function.

C++ also provide more methods to delete the element or multiple elements from the given vector. Some of them are as follows:

The remove() function shift an element that have to be remove to the end of vector. The last element is then deleted by vector pop_back() method.

#include <bits/stdc++.h>
using namespace std;

int main() {
    vector<int> v = {1, 5, 7, 4};

    // Shifting 7 to the end of vector
    remove(v.begin(), v.end(), 7);
  
  	// Deleting the last element i.e. 7
    v.pop_back();

    for (auto i : v)
        cout << i << " ";
    return 0;
}

We can also use vector erase() method to delete the last element.

The vector clear() method is used when all the elements of the vector have to be removed.

#include <bits/stdc++.h>
using namespace std;

int main() {
    vector<int> v = {1, 5, 7, 4};

  	// Removing all the elements
    v.clear();

    for (auto i : v)
        cout << i << " ";
    return 0;
}

Output

(empty)
