Programming Help Needed

Hey,

I am trying to do the following using a for() statement.

It's in C (but if you know it in ANY language, its almost universal).

I need to outprint something liek this

lililililililili
lilililililili
lililililili
lilililili
lililili
lilili
lili
li

That would be the number "8" if the user inputted 8 it would do a for() loop and show that.

if it was a 7 they inputted, it would do this

lilililililili
lililililili
lilililili
lililili
lilili
lili
li

Ya know?

Please, I need this asap.

Thanks!

Is "inputted" really a word?

That's beside the point ;)

hehe.

Anyone?

Here's PHP. The logic is the same for java/c/etc
[code1b785c2bbda]
$input = readLine(); // or whatever

for(int $i = $input; $i > 0; $i--)
{
for(int $j = 0; $j < $i; $j++)
{
echo "li";
}
echo "\n";
}
[/code1b785c2bbda]

What is the highest # you want to allow them to input? I know in PHP you could just use if/elseif if it was a small enough span if numbers you want to work with.

Yeah, it's a loop inside a loop. I was writing it out in C++, but someone walked in the room and I saw Admin already did it in another frame.

[code1d98cc98851]
cout << "How many stars?" << endl;
cin >> numstars; // or whatever

for(int i = numstars; i > 0; i--)
{
for(int j = 0; j < i; j++)
{
cout << "8";
}
cout << endl;
}
[/code1d98cc98851]

Theres c++ if it makes you feel better. I would have done it a tit bit different, but I'm lazy, so I just used his code.

This was like day three of AP Java, ha ha.

Awesome, thank you Admin.

Alright, now I got 2/4 done.

I also need to do this, which I have been stuck on for hours

Output

[code11ddb2d651d]
lililili
lilili
lili
li
[/code11ddb2d651d]

I know you would be checking for the number of spaces, but im stuck.. any clues?

Thank you Admin, by the way, I appreciate it

for the second question, this is in java.

[code1a2baf2d81d]
public static void recursion (int x, int y)
{
for (int i = 0; i < x; i++)
{
for (int j = 0; j < y - x; j++)
{ System.out.print ("li"); }
}

recursion (x-1, y);
}

public static void main (String[] args)
{
int x;

System.out.println ("Enter a number: ");
x = Stdin.readInt ();

recursion (x, x);
}[/code1a2baf2d81d]

I'm glad they are asking you shit that you really need to know...

Heh, yeah.

Assuming n is the number inputted

[code1c766c5e79a]
for (int i=0; i<n; i++)
{
for (int j=0; j<n-i; j++)
{
printf ("li");
}
printf ("\n");
}
[/code1c766c5e79a]

Just make sure you actually understand the code...or you're not going to know what you're doing next week in class ;)

Well, I know the code, it makes sense when I go through it in my head, but I am just stumped on loops, they confuse me a lot.

opps, i forgot to mention. my post in response to your second question utilizes recursion. i dont know if you guys touched that yet.

Recursion is against my religion.

We haven't got there quite yet,

Do you know how I would do that without 'recursion' or whatever?

It's all gotta be through a for() loop

[quoted8ca11bec6="Ryanish"]Well, I know the code, it makes sense when I go through it in my head, but I am just stumped on loops, they confuse me a lot.[/quoted8ca11bec6]

Here's a cool way to do it. Assuming n is the given number.

[code1d8ca11bec6]
charli outstring = (charli) malloc ( n+1);
int i;

outstring[n] = '\0';
for (i=0; i<n; i++)
{
memset (outstring, ' ', i);
memset (outstring, 'li', n-i);
printf ("%s\n", outstring);
}

free(outstring);
[/code1d8ca11bec6]

I don't have a compiler handyso I can't check to be sure ...

Anyway you should probably stick to a two for loops.

Eh, yeah..
I haven't been able to get it to work..

Here's what ive got for outputting this
[code1a9072e8132]
userint = 7

lilililililili
lililililili
lilililili
lililili
lilili
lili
li

number = 7
li
lili
lilili
lililili
lilililili
lililililili
lilililililili
[/code1a9072e8132]


Eh.. having trouble!

i've got
[code1a9072e8132]
nextint = userint;
for (x = 0; x < userint; x++)
{
for (y = 0; y < (x - userint); y++)
{
printf("%c", &usersymbol);
}
printf("\n");
}
[/code1a9072e8132]

^^ don't work.

The double for loop version


[code1953d352ee3]
for (int i=0; i<n; i++)
{
for (int j=0; j<i; j++)
{
printf (" ");
}

for (int j=0; j<n-i; j++)
{
printf ("li");
}
printf ("\n");
}

Thanks..

Is there a more efficient way of doing this
[code11dff765284]userint = userint + 1;
for (x=0; x<userint; x++)
{
for (y=0; y<x; y++)
{
printf ("li");
}

for (y=0; y<userint-x; y++)
{
printf (" ");
}
printf ("\n");
} [/code11dff765284]

I can't seem to think how to make it outprint this

[code11dff765284]
li
lili
lilili
[/code11dff765284]

Any pointers?

BTW, once I see the stuff, I learn it really quickly, my brain just gets confused when I try to do like 2 for loops in my head and see the result. I guess it's just one of those gotta-knows ?

you are a real novice ryanish, keep working on experimental projects and reading up on books. good luck man

Yeah, thanks.. ) I'm in an introductory class right now for C Programming / Java / C++, so I should learn a lot this semester.

I plan to go on to more advance classes in the future and learn outside of class too.

It's fun! P

just do what you do for

lilili
lili
li

the other way around.

Yea, you can get carried away in it and start thinking of crazy huge creations and projects. Don't let it get to your head though, that just makes things harder. Take it easy and keep working on it, soon you will be a pro, and classses help a lot!!!! So do online sites (but only if you are in the mood and have a very large interest)

Yup, I was fooling around with it and did it that way (before you posted) and I got it.

Thanks anyways.

Finally finished this project, feels good that I did 70% of it on my own.

Hehe, I will defenitely learn not to do assignments 2 hours before they are due (it's due tonight online by 1200 AM PST.. and I forgot about it).

Thanks to all that helped.

I gotta be honest... these are pretty basic logic exercises. they're really more tests of your logic and thoroughness and ability to think within a certain pattern than they are programming tests. if you're really struggling with these you might want to consider a different course. The level 2 programming course at my school has a 50% failure rate. You have to have a certain mind for it...

Remember, I am learning, I'm not in any advanced courses yet.

If I started the assignment 2 days prior, I would have been able to do it. I get faster as I get more familiar with the stuff.. I can do while loops pretty easily now, just getting into for() loops now..

I don't think I'll have a problem, I'm pretty accustomed to most everything else.
