Re: floyd triangle
Did you have any specific java programming questions? That sounds like a homework assignment. We'll help you with any java programming problems writing the program.
If you don't understand my answer, don't ignore it, ask a question.
Re: floyd triangle
no my assignment is the above given problem. i'm getting a triangle but not getting a single line which is required. pl do help
Re: floyd triangle
Post any code you have so far and explain where in the code you need the help.
People will be able to help you easier if they have something visual to look at.

Re: floyd triangle
If you already have the code to print the entire triangle it should be rather trivial to limit the output to the desired line.
Re: floyd triangle
import java.util.Scanner;
class FloydTriangle
{
public static void main(String [] args)
{
int n, i, c;
Scanner in = new Scanner(System.in);
System.out.println("Enter the number of rows of Floyd's triangle to print\n");
n = in.nextInt();
int a=n*(n-1)/2+1;
for (c = 1; c <= n; c++)
{
System.out.print(a+"");
a++;
}
System.out.println("\t");
}
}
i have the code.can someone explain this line (int a=n*(n-1)/2+1
Re: floyd triangle
Please edit your post and wrap your code with code tags:
[code=java]
YOUR CODE GOES HERE
[/code]
to get highlighting and preserve formatting.
It defines an int variable: a, evaluates an expression and assigns the value of that expression to a.explain this line (int a=n*(n-1)/2+1;

Re: floyd triangle
Do you have code that compiles and executes manually and gives the desired results?

Re: floyd triangle
If you have working code that prints out all lines of the triangle all you need to do is add some sort of control that only prints the desired line. What kind of control statement do you think that would be?
