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   3
4   5   6
7   8   9   10

C++ Program For Printing A Floyd's Triangle.

/* Declaration Of Header Files */
# include <iostream.h>
# include <conio.h>

/* Start Of Main Program */
void main()
{
   /* Declaration Of Variables */
   int a, b, c, rows;
   clrscr();
 
   /* Asking For The Input From User */ 
   cout << " Enter No. Of Rows To Print : ";
   cin >> rows;
 
   /* Source Code For Computing Floyd's Triangle */
   b  =  1;
   for ( a = 0; a < rows; a++ )
   {
       for ( c = 0; c <= a; c++ )
       {
           if (  b  <  10  )
              cout << b << "  ";
           else
              cout << b<< "  ";
              b++;
