C++ Pyramid Shape

pyramid is a polyhedron

A pyramid is a polyhedron for which the base is a polygon and all lateral faces are triangles. In this lesson, we'll only concern ourselves with pyramid whose lateral faces are congruent  that is, they're the same size and shape.  

 Example

#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
int j,z;
for(j=0;j<=10;j++)
{
for(int s=j;s<=10;s++)
cout<<" ";
for(z=0;z<=j*2;z++)
cout<<" *";
cout<<endl;
}
getch();
}
