In this tutorial, we will discuss Hollow Pyramid Pattern in Cpp using nested while loop
In this program, we are going to learn about how to display Hollow Pyramid Pattern using nested while loop in C++ language
Here, we display the Hollow Pyramid Pattern program with coding using nested while loop and also program get input from the user using cin function in C++ language
The user can provide numbers as they wish and get the Hollow pyramid pattern according to their input.
Hollow Pyramid triangle star pattern
Program 1
#include <iostream> #include <conio.h> using namespace std; int main() { int rows; cout<<"Enter the number of rows to Pyramid: "; cin>>rows; int i,j,k; i=1; while(i<=rows){ j=i; while(j<rows){ cout<<" "; j++; } k=1; while(k<2*i){ if(i==rows || (k==1 || k==2*i-1)) cout<<"*"; else cout<<" "; k++; } i++; cout<<"\n";//Move to the next line for print } getch(); return 0; }
When the above code is executed, it produces the following results
Inverted Hollow Pyramid triangle star pattern
Program 2
#include <iostream> #include <conio.h> using namespace std; int main() { int rows; cout<<"Enter the number of rows to Pyramid: "; cin>>rows; int i,j,k; i=rows; while(i>=1){ j=rows; while(j>i){ cout<<" "; j--; } k=1; while(k<2*i){ if(i==rows || (k==1 || k==2*i-1)) cout<<"*"; else cout<<" "; k++; } i--; cout<<"\n";//Move to the next line for print } getch(); return 0; }
When the above code is executed, it produces the following results
