int main()
{
 cout<<"size of int "<<sizeof(int)<<endl;
 cout<<"size of float "<<sizeof(float)<<endl;
 cout<<"size of double "<<sizeof(double)<<endl;
 cout<<"size of long "<<sizeof(long)<<endl;
 cout<<"size of long double "<<sizeof(long double)<<endl;
 cout<<"size of long long int "<<sizeof(long long int)<<endl
