Floyd Triangle in C with 0 and 1 Only


In the world of programming, the Floyd Triangle is a fascinating pattern that can be generated using the C programming language.

This pattern consists of consecutive numbers arranged in the shape of a right-angled triangle.

What makes this triangle even more intriguing is the constraint that only the numbers 0 and 1 are used in its construction.

In this article, we will explore the concept of the Floyd Triangle in C with 0 and 1 Only and learn how to implement it in code. So, let’s dive in!

What is the Floyd Triangle?

The Floyd Triangle, named after computer scientist Robert W. Floyd Triangle is a triangular pattern that forms by printing a sequence of numbers in a specific manne.

The pattern begins with 1 at the top, followed by the numbers incrementing by 1 in each subsequent row. T

he Floyd’s Triangle in C with 0 and 1 Only has a key feature: it uses only the digits 0 and 1 for its construction.

Implementing the Floyd Triangle in C

To create the Floyd Triangle in C with 0 and 1 Only, we need to use loops and conditional statements.

Let’s take a look at the code snippet below:

#include <stdio.h>

int main() {
   int rows, i, j, number = 1;

   printf("Enter the number of rows: ");
   scanf("%d", &rows);

   for (i = 1; i <= rows; i++) {
      for (j = 1; j <= i; j++) {
         printf("%d ", number % 2);

   return 0;

In the code above, we start by taking input from the user for the number of rows they want in the Floyd’s Triangle.

We then use nested for loops to iterate through each row and column of the triangle. The variable number keeps track of the current number to be printed.

We use the modulus operator % to alternate between 0 and 1 while printing the numbers.

Finally, we print a newline character \n after each row to move to the next line.

Explaining the Code

Let’s break down the code and understand each component:

Taking User Input

printf("Enter the number of rows: ");
scanf("%d", &rows);

This part of the code prompts the user to enter the number of rows they want in the Floyd Triangle. The input is stored in the variable rows using the scanf function.

Generating the Floyd’s Triangle

for (i = 1; i <= rows; i++) {
   for (j = 1; j <= i; j++) {
      printf("%d ", number % 2);

The outer for loop controls the number of rows in the triangle. It starts from 1 and continues until it reaches the user-defined number of rows.

The inner for loop is responsible for printing the numbers in each row. The variable i represents the current row, and the loop runs from 1 to i, printing the appropriate number at each position.

The % 2 operation ensures that only 0 and 1 are printed, as the modulus of any number by 2 can only be 0 or 1.

After each number is printed, we increment the number variable to maintain the sequence.


Q1: What is the significance of using only 0 and 1 in the Floyd Triangle?

The use of only 0 and 1 in the Floyd Triangle adds an element of constraint and simplicity to the pattern. It showcases the creative ways in which programming can be used to generate complex shapes using minimal resources.

Q2: Can the Floyd Triangle be constructed with numbers other than 0 and 1?

Yes, you can construct the Floyd Triangle using any sequence of numbers. However, the charm and uniqueness of the this triangle lie in its limitation to only 0 and 1.

Q3: How can I modify the code to print a larger Floyd Triangle?

To print a larger Floyd Triangle, you can simply input a higher number of rows when prompted by the program. The code will generate the triangle accordingly, accommodating the desired number of rows.

Q4: Is the Floyd Triangle limited to right-angled triangles only?

Yes, the Floyd Triangle is specifically a right-angled triangle. It follows the pattern of incrementing numbers row by row, creating a triangular shape with a right angle.

Q5: Can the Floyd Triangle be implemented in languages other than C?

Yes, you can implement the Floyd Triangle in various programming languages. The logic remains the same, but the syntax may differ based on the language you choose.

Q6: Are there any practical applications of the Floyd Triangle?

While the Floyd Triangle is primarily a pattern generated for aesthetic purposes and learning programming concepts, it can be used as a building block for more complex algorithms and data structures. The triangle’s unique properties and the skills developed while implementing it can be applied in various problem-solving scenarios.
