C Exercises: Print the Floyd's Triangle
22. Floyd's Triangle
Write a program in C to print Floyd's Triangle.
The Floyd's triangle is as below :
1 01 101 0101 10101
This C program prints Floyd's Triangle, a triangular array of binary numbers (0s and 1s). The program prompts the user for the number of rows and then generates the triangle by alternating between 0s and 1s in a specific pattern. The resulting triangle is printed row by row, creating a visually distinct pattern with each row having an increasing number of elements.
Visual Presentation:
Sample Solution:
C Code:
#include <stdio.h> // Include the standard input/output header file.
void main()
{
int i, j, n, p, q; // Declare variables to store input and control loop indices.
printf("Input number of rows : "); // Prompt the user for input.
scanf("%d", &n); // Read the value of 'n' from the user.
for (i = 1; i <= n; i++) // Loop for the number of rows.
{
if (i % 2 == 0) // Check if 'i' is even.
{
p = 1;
q = 0;
}
else // If 'i' is odd.
{
p = 0;
q = 1;
}
for (j = 1; j <= i; j++) // Loop for each element in the row.
{
if (j % 2 == 0) // Check if 'j' is even.
printf("%d", p); // Print 'p' if 'j' is even.
else
printf("%d", q); // Print 'q' if 'j' is odd.
}
printf("\n"); // Move to the next line after printing a row.
}
}
Output:
Input number of rows : 5 1 01 101 0101 10101
