swap vector c++ code example
Example 1: swap two elements of a vector
std::iter_swap(arr.begin()+pos1,arr.begin()+pos2);
Example 2: C++ Vector swap syntax
vector<T>().swap(x);
Example 3: swap vector c++
vector1.swap<vector2>;
Example 4: C++ Vector swap
#include <iostream>
#include <vector>
int main ()
{
std::vector<int> myvector;
myvector.push_back (100);
myvector.push_back (200);
myvector.push_back (300);
std::cout << "myvector contains:";
for (unsigned i=0; i<myvector.size(); i++)
std::cout << ' ' << myvector[i];
std::cout << '\n';
myvector.clear();
myvector.push_back (1101);
myvector.push_back (2202);
std::cout << "myvector contains:";
for (unsigned i=0; i<myvector.size(); i++)
std::cout << ' ' << myvector[i];
std::cout << '\n';
return 0;
