vector size

#include<iostream>
#include<vector>
using namespace std;
int main(){
  //Creation of integer vector
  vector<int> vectorArray {1,2,3,4,5,6,7,8,9};
  //Created vector has 9 elements on it 
  int sizeOf_vectorArray= vectorArray.size();
  
  cout<<sizeOf_vectorArray; // Output will be 9
  
  vectorArray.push_back(10); // 10 will be added in the end of the vector
  
  sizeOf_vectorArray=vectorArray.size();
  
  cout<<sizeOf_vectorArray; // Output will be 10
  
  vectorArray.push_front(0); //0 will be added in the begining of the vector
  
  sizeOf_vectorArray=vectorArray.size();
  
  cout<<sizeOf_vectorArray; // Output will be 11
  
  return 0;
