#include <stdlib.h>
#include <stdio.h>
#include <vector>
#include <iostream>

using namespace std;

int main(int argc, char* *argv)
{

vector<int> vct;
vct.push_back(100);
vct.push_back(100);
vct.push_back(100);
vct.push_back(100);
vct.push_back(100);
vct.push_back(100);
vct.push_back(100);
vct.push_back(100);

for ( int& value : vct )
{
cout << value << endl;
