[2.0] Could this code be impossible to write??

[Fromethius]

Hello,

Let's say the user inputs the number 7. THe program will output this:

7
66
555
4444
33333
222222
1111111

The rules my teacher stated is ONLY for loops. No if statements, just for loops. You can nest a for loop but that is all. Can anyone solve this?

[RobDog888]

Loop backwards using a counter variable to increment the printing of the loop value.

[RobDog888]

For i = 7 to 1 step -1
    for x = 1 to 7
        conmsole.writeline(i);
    next
next

Something like that.

rob u could rack up a triple post if u translated that to c#. nah i got it don't worry thanks i'll try it out

[Fromethius]

yea it doesn't work i just get this as a result:

7777777
6666666
5555555
4444444
3333333
2222222
1111111

using... this code:

		for (int i = 7; i >= 1; i--) {
			for (int x = 1; x <= 7; x++) {
				System.out.print(i);
			}
			System.out.println();
		}

lol, naw. I just thought some pseudocode would be better explaination.
The write needs to write on the same line. In VB the semicolon identifies a print continuation. Oh add a new line print after the inner loop to get it to move to the next line.

Im sure there may be better .net ways to do it but this was my first thought.

Edit: Should be x = 1 to z where z would be 7 - i

[Harsh Gupta]

for(int i = 7; i >= 1; --i)
{
    for(int x = 7; x >= i; --x)
    {
         Console.Write(i);
    }
    Console.WriteLine();
}

Alternatively:

for(int i = 7; i >= 1; --i)
{
    for(int x = 0; x <= 7-i; ++x)
    {
         Console.Write(i);
    }
    Console.WriteLine();
}

[RobDog888]

for i = 7 to 1 step -1
    z = z + 1
    for x = 1 to z
        conmsole.writeline(i);
    next
next

[Fromethius]

gracias!! it works great:

		for (int i = n; i >= 1; --i) {
			for (int x = n; x >= i; --x) {
				System.out.print(i);
			}
			System.out.println();
		}

without nested loops:

int iNum = 0;
Console.WriteLine("Input A Value");
string sNum = Console.ReadLine();
if (int.TryParse(sNum, out iNum))
{
    string Buffer = "";
    for (int i = iNum; i > 0; --i)
    {
        Console.WriteLine(Buffer = new String(i.ToString()[0], iNum - i + 1));
    }
}
else 
{
    Console.WriteLine("No Good!");
}
Console.ReadLine();

(i'm answering this as much for my benefit as the posters - so if anyone can tell me if i'm doing something i shouldn't be, I'd like to hear it)

edit: slight correction (+1)

[Harsh Gupta]

Buffer = new String(i.ToString()[0], iNum - i + 1)

[bushmobile]

too slow, harsh!

[Harsh Gupta]

the connection is too slow today.

Furthermore, the i.ToString()[0] won't work good if number is a more than 9. It will display only the first digit.

I don't know if it matters.

yeah, I was aware of that - I assumed the question only meant for single digit numbers, otherwise the triangle doesn't make sense.

[RobDog888]

My original logic code example in C3 (finally lol).

private void button1_Click(object sender, EventArgs e)
{
    int z = 1;
    for(int i = 7; i >= 1; --i)
    {
        z = 7-i;
        for (int x = 0; x <= z; --z) 
        {
            textBox1.Text = textBox1.Text + i;
        }
        textBox1.Text = textBox1.Text + Environment.NewLine;
    }
}

How to do it on a WinForm ? (as there is no Print method)

[Harsh Gupta]

How to do it on a WinForm ? (as there is no Print method)

using GDI+, look for Graphics.DrawString() (+6 overloaded) functions. Works for functions having PaintEventArgs parameter.

[RobDog888]

Why would you want to draw this directly on a form?

[Fromethius]

cuz everyone loves a big number triangle as a form background picture!

So what grade did we get?

Maybe we should have a homework forum?

[penagate]

Bad wossname, you didn't use a for() loop.

for (;false;);
Console.Write("7\n66\n555\n4444\n33333\n222222\n1111111\n");

{
     Console.WriteLine("7\n66\n555\n4444\n33333\n222222\n1111111\n");
}

there...solved taht problem!

[wossname]

I wonder if you guys can print this output without using an if statement (the ?: operator is not allowed either)...

[penagate]

Console.Write("18\n18\n16 16 14\n14\n12 12 10\n10\n8 8 6\n6\n4 4 2\n2\n0 0");

[wossname]

Do it properly smartarse.

[brendan6]

Haha..smartass says the guy that tried to pull that stunt to begin with

[wossname]

Yeah but the first time it was original.

Twas extra credit. I now have a 105 in programming class
