using namespace std;
int main()
{
   cout<<"\"Hollow Triangle Shape\"\n\n";
  int z=1;

  for (int i=0; i<7; i++)
  {
    for (int j=7; j>i; j--)
    {
      cout<<" "; // displaying space here
    }
    cout<<"*";   // displaying asterisk here

    if (i!=0)
    {
      for (int k=1; k<=z; k++)
      {
        cout<<" ";
      }
      cout<<"*";
      z+=2;
    }
    cout<<endl;  // endl is for new line
  }

  for (int i=0; i<=z+1; i++)
  {
    cout<<"*";
  }

return 0;
}


Sample Output of the program
sample output Hollow triangle shape in c++ programing code


To increase or decrease the size of triangle change the value of loop variables. It is recommend to change the code and examine the output it will be more helpful.
