Program:

#include<iostream>
using namespace std;

int main()
{
int i,j,no;
cin>>no;
if(no>=3)
{
for(i=1;i<=no;i++)
{
if(i==1 || i==no)
{
for(j=1;j<=no;j++)
{
cout<<"* ";
}
}
else
{
for(j=1;j<=no;j++)
{
if(j==1 || j==no)
{
cout<<"* ";
}
else
{
cout<<" ";
}
}
}
cout<<endl;
}
}
else
{
cout<<"Input value has to be greater or equal to 3 i.e. 3 is the lowest number!";
}
