This is also one of the basic interview questions for the freshers.
This is a right-angled triangular array of natural numbers, used in computer science education.
This Floyd’s triangle is defined by filling the rows of the triangle with consecutive numbers, starting with a 1 in the top left corner

1 2 3 4 5 6 7 8 9 |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
Here is the example program to print the Floyd’s triangle in C.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |
#include "stdafx.h" #include <stdio.h> #include <stdlib.h> int main () { int iCount, i, Ind, iVaribleTemp = 1; printf("Enter the number of rows of Floyd's triangle \n"); scanf("%d", &iCount); for (i = 1; i <= iCount; i++) { for (Ind = 1; Ind <= i; Ind++) { printf ("%d ",iVaribleTemp); iVaribleTemp++; } printf("\n"); } return 0; } |
The output of the above program is

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
