In this tutorial you will learn about the C++ Program to Create Floyd’s Triangle and its application with practical example.
In this tutorial, we will learn to create a c++ program that will create a Floyd’s Triangle using c++ programming.
Prerequisites
Before starting with this tutorial we assume that you are best aware of the following C++ programming topics.
- if-else Statements.
- Looping statement.
- Basic input/output.
- Operators.
What is Floyd’s Triangle ?
It is named after Robert Floyd who created this Triangular shape. Floyd’s triangle is a triangular array of numbers.It is a method of showing ,filling the rows of the triangle with consecutive numbers, starting with a 1 in the top left corner.
C++ Program to Creating a Floyd’s Triangle
In this program we will print Floyd’s Triangle using nested for loop. We would first declared and initialized the required variables. Then we will create the Pyramid using below program.

#include <iostream> using namespace std; int main() { int i,j,num = 1; for(i = 1; i <= 5; i++) { for(int j = 1; j <= i; ++j) { cout << num << " "; ++num; } cout << endl; } return 0; } |
Output
In the above program, we have first declared and initialized a set variables required in the program.
- i & j= for iteration.
In above program first we declare variables i and j, here we use 2 for loops.The outer loop will run for number of rows or pyramid and the inner loop print the Floyd’s Triangle to be displayed in each row.This is displayed using the following code.
And the final output of our program is like that.
