c++ reverse vector

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

int main()
{
    vector<int> nums{4,1,2,1,2};

    reverse(nums.begin(), nums.end());
    return 0;
}

C++ reverse vector

// C++ program to reverse Vector
// using reverse() in STL
 
#include <bits/stdc++.h>
using namespace std;
 
int main()
{
 
    // Get the vector
    vector<int> a = { 1, 45, 54, 71, 76, 12 };
 
    // Print the vector
    cout << "Vector: ";
    for (int i = 0; i < a.size(); i++)
        cout << a[i] << " ";
    cout << endl;
 
    // Reverse the vector
    reverse(a.begin(), a.end());
 
    // Print the reversed vector
    cout << "Reversed Vector: ";
    for (int i = 0; i < a.size(); i++)
        cout << a[i] << " ";
    cout << endl;
 
    return 0;
}

how to reverse a vector

//vector<int> A;
reverse(A.begin(),A.end());

c++ reverse part of vector

//Reverse vector partially (from index x to index y)
reverse(v.begin()+x, v.begin()+y+1);

c++ reverse vector

#include <vector>
#include <algorithm>

int main() {
  std::vector<int> a;
  std::reverse(a.begin(), a.end());
  return 0;
}

reverse in vector c++
