Here, we are going to learn how to print Floyd's triangle in C#?
Submitted by Nidhi, on October 03, 2020
Here, we will Floyd's triangle using nested loops on the console screen.
Program:
The source code to print Floyd's triangle is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.
//C# program to print Floyd's triangle
using System;
class MathEx
{
static void Main(string[] args)
{
int outer = 1;
int inner = 1;
int num = 1;
int rows = 0;
Console.Write("Enter the number of rows: ");
rows = int.Parse(Console.ReadLine());
for (; outer <= rows; outer = outer + 1)
{
for (inner = 1; inner < outer + 1; inner++)
{
Console.Write(num + " ");
num = num + 1;
}
Console.WriteLine();
}
}
}
Output:
Enter the number of rows: 8
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
Press any key to continue . . .
Explanation:
Here, we created a class MathEx that contains a Main() method, In the Main() method we declared 4 variables outer, inner, num, and rows initialized with 1,1,1 respectively. Then read the value of rows from the user.
for (; outer <= rows; outer = outer + 1)
{
for (inner = 1; inner < outer + 1; inner++)
{
Console.Write(num + " ");
num = num + 1;
}
Console.WriteLine();
}
In the above code, we print Floyd's triangle, here the outer loop is executed 1 time for each row and the inner loop is executed to print elements of the row.
