int main ()

{

int t[]={1,2,3,4,5};

std::vectorv1(t,t+5);

std::vectorv2(v1);

v1.resize(10);

v2.reserve(10);

std::vector::iterator i = v1.begin();int ii = 0;

while (i != v1.end()) { std::cout<<i[ii]<<" ";ii??;i++; }

i = v2.begin();ii=0;

while (i != v2.end()) { std::cout<<i[ii]<<" ";ii??;i++; }

return 0;
