For loops to create four right triangle histograms...HELP!!

[simpleeshelbee]

Hey all,
This is my first post. I am really hoping that someone out there has a solution to my C++ coding problem...

This is my code and what I have to do...
I think it is rows of 1 - 10 and then back

************************************************** ******************************************

//These histograms are supposed to print beside eachother like this:

//* ******************** *
//** ********* ********* **
//*** ******** ******** ***
//**** ******* ******* ****
//***** ****** ****** *****
//****** ***** ***** ******
//******* **** **** *******
//******** *** *** ********
//********* ** ** *********
//*********** ***********
//but I can't make them go beside eachother. My code below makes two of them,
//but they are one under the other!! Not what I need....

//HELP??????



#include <iostream>
using namespace std;

int count;


main()
{



for(int count_1=1;count_1<=10;count_1++)
{
for(int count_2=1;count_2<=count_1;count_2++)
cout<<"*";

cout<<endl;
}

cout << "\n";

for(int count_3=1;count_3<=10;count_3++)
{
for(int count_4=10;count_4>=count_3;count_4--)
cout<<"*";

cout<<endl;

}


cout << "\nPress q and then Enter to quit-->"; //
char dummy;
cin >> dummy; //Wait for input
return 0;

} // main
************************************************** *****************************************

Help anyone, please!!!!!!!

Thanks,

This line

cout<<endl;

and this line

cout << "\n";

are equivilent and moves the output onto a new line.

If you don't want to start on a new line then don't run this line of code.

[simpleeshelbee]

Hey,
Thanks for responding.

I tried that, just now again, and then it runs one of the triangles and the other is all on the first line in one long line of asterisks...! LOL It's making me crazy!! I thought about pulling my hair out, but I would look funny!! LOL HELP...?

Stuck again...?

If you think about it, you can't add lines to what you already outputted. What I believe you're trying to do is add the triangles to what you've already outputted.

I believe what you are doing is equivalent to trying to do this:

cout << "super";
cout << endl;
cout << "man";

and you're expecting superman, yet you get super/man.

I think your whole algorithm needs refining. Let me see what I can do, I'll get back to you.

[luninspectra]

I have refined the source code for you, its probably not exact, but the output is this:

-bash-3.00$ a.out
* ********** ********** *
** ********* ********* **
*** ******** ******** ***
**** ******* ******* ****
***** ****** ****** *****
****** ***** ***** ******
******* **** **** *******
******** *** *** ********
********* ** ** *********
********** * * **********


Press q and then Enter to quit-->q
-bash-3.00$

Here's the refined source code:

//These histograms are supposed to print beside eachother like this:
//* ********** ********** *
//** ********* ********* **
//*** ******** ******** ***
//**** ******* ******* ****
//***** ****** ****** *****
//****** ***** ***** ******

//*********** ***********
//but I can't make them go beside eachother. My code below makes two of them,

//HELP??????



#include <iostream>
using namespace std;


int count;

int main() {

for(int stars = 1; stars <= 10; stars++) {
for(int count = 1; count <= stars; count++) {
//It'll print the amount of stars
cout << "*";
if(count == stars)
cout << " ";
}

for(int count_2 = 10; count_2 >= stars; count_2--) {
cout << "*";
if(count_2 == stars)
cout << " ";
}

for(int count_2 = 10; count_2 >= stars; count_2--) {
cout << "*";
if(count_2 == stars)
cout << " ";
}

for(int count = 1; count <= stars; count++) {
cout << "*";
if(count == stars)
cout << " ";
}


cout << endl;
}

cout << "\n";

cout << "\nPress q and then Enter to quit-->"; //
char dummy;
cin >> dummy; //Wait for input

return 0;

}

Hope ya like it ;).

Hey!!

Thanks so much! The code was great...except that I need the two middle triangles turned the other way. I will try and look at your code to see what is needed to turn them around, but your code has come closer than anything I could figure out!!

In the diagram that I have here, the two middle right triangles are supposed to have their straight sides facing the other way. So, the straight side of triangle two should face triangle one, and the straight side of triangle three should face triangle four. Make sense? I hope you can fix it because I don't know if I can...LOL.

Thanks so much and will be checking back often to see your response!! :)

More Help !!!!????

PLEASE??

[luninspectra]

Can you draw what you mean? I don't understand what you mean by having the two middle triangles facing the other way...I'll see what I can do once you aid me visually :).

[simpleeshelbee]

Hey there!

Sure I will try to draw it here...(the last time that I drew it, it didn't leave enough space between the four triangles, LOL)

Hope it stays the same when I post this...

Thanks so much!

[simpleeshelbee]

It didn't...
I am going to put it on here with letters instead, for display purposes, but I still need the results in asterisks and spaces.
So, the "a" will stand for the asterisks and the "p" will be spaces. The asterisks are in sets of 10.

apppppppppaaaaaaaaaaaaaaaaaaaapppppppppa
aappppppppaaaaaaaaappaaaaaaaaappppppppaa
aaapppppppaaaaaaaappppaaaaaaaapppppppaaa
aaaappppppaaaaaaappppppaaaaaaappppppaaaa
aaaaapppppaaaaaappppppppaaaaaapppppaaaaa
aaaaaappppaaaaappppppppppaaaaappppaaaaaa
aaaaaaapppaaaappppppppppppaaaapppaaaaaaa
aaaaaaaappaaappppppppppppppaaappaaaaaaaa
aaaaaaaaapaappppppppppppppppaapaaaaaaaaa
aaaaaaaaaaappppppppppppppppppaaaaaaaaaaa


Now, I will go line for line in words to explain what happened up there...LOL.
1st line - 1 'a', 9 'p', 10 'a', 10 'a', 9 'p', 1 'a'
2nd line- 2 'a', 8 'p', 9 'a', 1 'p', 1 'p', 9 'a', 8 'p', 2 'a'
3rd line - 3 'a', 7 'p', 8 'a', 2 'p', 2 'p', 8 'a', 7 'p', 3 'a'
etc....


Does that help? It messes up the view each time I try to post it with spaces instead of letters.
Thanks so much!!

[simpleeshelbee]

Was wondering if that last post helped any with visualizing what I need?

Thanks,
Shelbee

[simpleeshelbee]

Hey there! Just wanted to see if I was still remembered? Still need that code...? I was getting too far back on the board and thought maybe "outta sight, outta mind", LOL. Waiting to hear back from ya!

Thanks,
Shelbee

[simpleeshelbee]

Feel like I have been forgotten. Can anyone help me with this code? I really NEED it...like rightaway...

Thanks,
Shelbee

[simpleeshelbee]

Hey guys,
Can anyone turn those inside two triangles around? The best code I have, I got from here, but it has the inside two triangles' straight sides facing eachother when they should be facing the other way..?

Anyone? Please help...

Thanks,
Shelbee

[simpleeshelbee]

Still waiting to hear back about the loops...? Can anyone help me? I really need to figure out how to switch those triangles around that are in the middle...? Anyone??

Thanks,
Shelbee

I know this thread is outdated, but you know, 2 cents.

I am not sure on the code right now, but what you need to do is realize the difference between printing just one of those triangles out, stacked on top of each other, and having them all lined up. You need a starting loop that is going to define how many total LINES there are, and then a loop that is going to define how many characters, including the spaces, that are going on each line.

next:
You have up facing triangles @ 1 char each. You have 2 triangles that have their bases up @ 10 chars each. Then you have 3 spaces. So the first line is going to look like this:

* ********** ********** * = 25 chars
You need to find a way to adjust where the " " is going to be for lines 2 -10. The middle space will always be the same, the first space will need to be added to each time the loop comes around so that it moves right, the third space needs to be subtracted from so that it moves left.

I am working and learning with C# and just finished a similar exercise where we just made the same shapes, just stacked on top of each other. I will see if I can come up with a solution to post here for you and others.

[dannyyoder1978]

I'm back, and sooner than I thought :)

Here is the code in C#, but it can be converted easily to any language.

---------------------------------------------

int space1 = 2; //variable that will move the first spacer right
int space2 = 24; //variable that will move the third space left

for (int L = 1; L <= 10; L++) //determines number of lines
{ //start first loop

for (int C = 1; C <= 25; C++) // determines chars per line

{ //start second loop

if (C == space1) // if the char location = space1, print a space

{

Console.Write(" ");

}

else if (C == 13) // if the char location = 13 (the middle) print space

{

Console.Write(" ");

}

else if (C == space2) //if the char location = space2, print space

{

Console.Write(" ");

}

else

{

Console.Write("*"); //all else fails, print *

}

}//end second loop

space1++; //incr. space1 by one
space2--; // decr. space2 by one

Console.WriteLine(" "); // new line

} //end first loop

--------------------------------------------------------------
Hope this helps, but I encourage you to study it and understand exactly how it is working instead of just copying it, or else you haven't learned anything, really.
