Write a program to print a Floyd's Triangle

Floyd's Triangle:

Floyd's triangle is a right-angled triangular array of natural numbers, used in computer science education. It is named after Robert Floyd. It is defined by filling the rows of the triangle with consecutive numbers, starting with a 1 in the top left corner:1 2 34 5 67 8 9 10 and so on....

Program:

import java.util.*;

class FloydsTriangle 

{

public static void main(String[] args)

{

int limit; //this variable is useful for howmany  rows we need?

System.out.println("Enter the limit: ");// asking for limit

Scanner sc=new Scanner(System.in);//taking the input from console

limit=sc.nextInt();//taking the input as integer

int count=1; // for printing purpose

for (int index=1;index<=limit ;index++ ) //this is for number of rows

{

  for (int index1=1;index1<=index ;index1++ ) //in particular row it displays the howmany numbers u want

  {

      System.out.print(count+" "); //printing the number by using the "print" method

  count++;// count increment

  

  }//inner for loop

  System.out.println("");// it is for nextline 

           

            }//outer for loop

}//main

}//class

Output:

Enter the limit:
