# Floyd's Triangle Program In C

Floyd's triangle, named after Rober Floyd, is a right angled triangle, which is made using natural numbers. It starts from 1 and consecutively selects the next greater number in sequence.

We shall here learn how to print floyd's triangle using C programming language.

## Algorithm

Algorithm should look like this −

Step 1 - Take number of rows to be printed, n. Step 2 - Make outer iteration I for n times to print rows Step 3 - Make inner iteration for J to I Step 3 - Print K Step 4 - Increment K Step 5 - PrintNEWLINEcharacter after each inner iteration Step 6 - Return

## Pseudocode

We can derive a pseudocode for the above mentioned algorithm, as follows −

procedure floyds_triangle FOR I = 1 to N DO FOR J = 1 to I DO PRINT K INCREMENT K END FOR PRINTNEWLINEEND FOR end procedure

## Implementation

Implementation of right triangle in C is as follows −

#include <stdio.h> int main() { int n,i,j,k = 1; n = 5; for(i = 1; i <= n; i++) { for(j = 1;j <= i; j++) printf("%3d", k++); printf("\n"); } return 0; }

The output should look like this −

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
