Drawing different shapes like triangles, diamonds, pyramids etc. is the very basics of programming and are very important to learn and understand. Let’s start how to draw a Reverse Pyramid shape in C++ programming code.

For other triangle, diamonds & Pyramid shapes see -> Patterns and Shapes in C++

 

We will make our program to draw following structure of reverse pyramid

* * * * * * * * *
  * * * * * * *
    * * * * *
      * * *
        *

Program:

#include <iostream>
using namespace std;
int main()
{
    int rows,i,j,space;
    cout<<"Enter number of rows: ";
    cin>>rows;
    for(i=rows;i>=1;--i)
    {
        for(space=0;space<rows-i;++space)
           cout<<"  ";
        for(j=i;j<=2*i-1;++j)
           cout<<"* ";
        for(j=0;j<i-1;++j)
           cout<<"* ";
        cout<<endl;
    }
    return 0;
}
