Drawing a w-wide h-high rectangular frame using asterisks

[shenzy9ace]

My lab is basically prompting the user first for the width and height, then using asterisks to draw it, Kinda lost as to where to go from here, Super beginner level

  #include <iostream>
using namespace std;

int main{

int w, h; //Variables for width and height, respectively

do {   //Getting dimensions of rectangle

  cout << "Enter width of desired rectangle (whole number >0)"<< endl;
  cin >> w;
  cout << "Enter height of desired rectangle (whole number >0)" << endl;
  cin >> h;
}

for(int i=0; i<h;i++)
   {
     for(int i=0; i<w; i++)

thanks for the help
