Using clear()

#include <iostream>
#include <vector>
using namespace std;

int main()
{
  vector<int> vectorObject;
  int i;

  for(i = 0; i <10; i++) 
     vectorObject.push_back(i);

  cout << "Initial contents of vectorObject: ";
  for(i = 0; i <vectorObject.size(); i++)
    cout << vectorObject[i] << " ";
  cout << endl;

  cout << "Initial size of vectorObject: ";
  cout << vectorObject.size() << endl;

  cout << "Initial capacity of vectorObject: ";
  cout << vectorObject.capacity() << "\n\n";

  vectorObject.clear();

  cout << "Size of vectorObject after clear(): ";
  cout << vectorObject.size() << endl;

  cout << "Capacity of vectorObject after clear(): ";
  cout << vectorObject.capacity() << "\n\n";

  // put new values in vectorObject
  for(i = 0; i <10; i++) 
     vectorObject.push_back(i*10);

  cout << "New contents of vectorObject: ";
  for(i = 0; i <vectorObject.size(); i++)
    cout << vectorObject[i] << " ";
  cout << endl;
  
  cout << "Size of vectorObject after adding new elements: ";
  cout << vectorObject.size() << endl;

  cout << "Capacity of vectorObject after adding new elements: ";
  cout << vectorObject.capacity() << "\n\n";

  return 0;
}
