reverse a vector in cpp code example

Example 1: 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;
}

Example 2: how to sort a vector in reverse c++

#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
int main() {
   vector<int> v = { 10, 9, 8, 6, 7, 2, 5, 1 };
   sort(v.begin(), v.end(), greater <>());
}

Example 3: c++ reverse part of vector

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

Example 4: reverse a vector

vector<int> a = {1,2,3,4,5,6};
reverse(a.begin(), a.end());

Example 5: reverse in vector c++

reverse(start_index, last_index);
