Reading contents of an array horizontally?

[YourBroAlex]

Now, what i need help with is how to being able to insert the string into the array and be able to read it HORIZONTALLY instead of vertically. How do i output the contents of an array horizontally instead of vertically?

So if i insert 1234569 in an multidimensional array, instead of showing it like this:

1 4 7
2 5 8
3 6 9

i want it to show like this:

1 2 3
4 5 6
7 8 9

Please explain clearly as i'm still pretty novice. Thanks!

i want it to show like this:

1 2 3
4 5 6
7 8 9

The output is always horizontal. To make it this way, all you have to do is simply make a
new line after 3 outputs -

#include <iostream>

using namespace std;

int main(){

	int arr[3][3] = 
	{
		{1,2,3},
		{4,5,6},
		{7,8,9}

	};

	for (int i = 0; i < 3; i++)
	{
		for (int j = 0; j < 3; j++)
		{
			cout << arr[i][j] << " ";
		}
		cout << "\n";
	}

	
	return 0;
}

Could you show me an example of a code where you actually insert the numbers and convert them so you can see them horizontally?

[TarikNeaj]

#include <iostream>

using namespace std;

int main(){

	int arr[3][3];
	std::string numbers = "123456789";

	int stringLooper = 0;
	for (int i = 0; i < 3; i++)
	{
		for (int j = 0; j < 3; j++)
		{
			arr[i][j] = numbers[stringLooper] - '0'; // converting from char to integer
			stringLooper++;
		}
	}
	for (int i = 0; i < 3; i++)
	{
		for (int j = 0; j < 3; j++)
		{
			cout << arr[i][j] << " ";
		}
		cout << "\n";
	}

	return 0;
}

Sorry for a bad example, but i didn't really mean integers. I was just using it as an example because when i explained my realt assignment, people were getting really confused.

My actual assignment is to insert a crypted message, and when it's read horizontally it would be decrypted. Could you pleaaasee be a friend and show that exact same example, but instead of numbers. show me abcdefghi horizontally in an array? I'm really lost :/

[TarikNeaj]

Do you mean simply filling an multidimensional string array with numbers 1-9 and then printing it out like that?

[YourBroAlex]

No, i mean filling a multidimensional array with a string, like in letters. So what i'm asking is if you could make a same example but instead of 123456789, you show me how to do abcdefghi.

It's just an example and nothing specific really, that's why i need a CIN in the beggining of the code :)

So you insert these letters and it will show as:

a b c
d e f
g h i

[TarikNeaj]

Something like this? -

#include <iostream>

using namespace std;

int main(){

	char arr[3][3];
	std::string numbers = "abcdefghi";

	int stringLooper = 0;
	for (int i = 0; i < 3; i++)
	{
		for (int j = 0; j < 3; j++)
		{
			arr[i][j] = numbers[stringLooper]; 
			stringLooper++;
		}
	}
	for (int i = 0; i < 3; i++)
	{
		for (int j = 0; j < 3; j++)
		{
			cout << arr[i][j] << " ";
		}
		cout << "\n";
	}
	system("pause");
	return 0;
}

You only had to change the type of the array, and from 1-9 to a-i. Then simply removing the - '0'

[YourBroAlex]

But in that code you wrote it automatically, how do i make it that i have to type it in manually?

so in the beginning in the code it's gonna ask something like:

cout << "Type in the letters: ";
cin >> abcdefghi

in this case, abcdefghi is the string.

I think you can figure that one out yourself, you've got a good template which I provided for you =) Goodluck!

[YourBroAlex]

Alright, thanks for your help! You have been ever so helpful to me! :)

[TarikNeaj]

I'd be happy to help out if you get stuck on a specific bit, but you're gonna need to put in lots of effort first :p

[YourBroAlex]

I figured it out! But i'm still not as done, as this does not fit my assignment.
Now when you seem to really understand the point of my program, i will attempt to try to explain it as well as i can.

Here is a sketch my teacher made: https://gyazo.com/33d90496958ef231dec7866e39ce1951

My assignment is to insert a string, to be specific this string; "DA PAE RTTTARE TRYR" If this
string is placed horizontally in a string, it will show a message;


D E T T
A Ä R
K R Y
P T E R
A T

It means "THIS IS CRYPTED" in Swedish. Any tips? You have been veeery helpful so far!! :)

#include <iostream>

using namespace std;

int main(){

	string arr[3][4];
	char c;

	for (int i = 0; i < 3; i++)
	{
		for (int j = 0; j < 3; j++)
		{
			cin.get(c);
			arr[i][j] = c;

		}
	}
	for (int i = 0; i < 3; i++)
	{
		for (int j = 0; j < 3; j++)
		{
			cout << arr[i][j] << " ";
		}
		cout << "\n";
	}

	return 0;
}

[TarikNeaj]

Sorry but I'm not following.

to be specific this string; "DA PAE RTTTARE TRYR"

-

it will show a message;


D E T T
A Ä R
K R Y
P T E R
A T

There is no "K" in the original string, so Im confused how K ended up in the message. You're probably gonna have to give it another go at explaining.

It means "THIS IS CRYPTED" in Swedish.

Jag vet ^_-

[YourBroAlex]

Hahahaha, awesome!! I'm going to continue using English for the benefit of other people to learn from this.

I think i misspelled the insert string (sorry for being so confusing >.<)

I will emphezise the blank spaces with a " _ ".

The string you are supposed to enter is: DA_PAE_KTTTÄRE_TRYR_

And it should look like this, when inserted into an array;

D E T T
A _ Ä R
_ K R Y
P T E R
A T _ _

Did i explain it well? :P

[TarikNeaj]

That makes more sense. The only question that remains is that. Do you want to insert it vertically or does it only have to be displayed vertically?

[YourBroAlex]

Hmm, it has to be printed out the way i wrote it on my last question, like it should look like that on the console. So basically just printing out the array.

[TarikNeaj]

The start is easy, simply filling the array with the string -

std::string words = "DA PAE KTTTÄRE TRYR ";
	char arr[5][4];

	int stringCounter = 0;
	for (int i = 0; i < 5; i++)
	{
		for (int j = 0; j < 4; j++)
		{
			arr[i][j] = words[stringCounter];
			stringCounter++;
		}
	}

Now this is where you have to start thinking. Because you can't just display it like it is, it will print out

D A _ P
A E _ K
T T T _
...
...

So what you want to do is develop some kind of pattern/algorithm, which displays them the way you want it to. Basically the algorithm is -

Display the first Letter, which is D, then 5 characters to the right, which is E, then 5 characters to the right, which is T, then 5 characters to the right, which is T.

Now start from second character, 5 characters to the right which is _ ... and so on, until it's displayed like you want it to.

Work hard on this, I'd like to see the progress you make =)

[YourBroAlex]

I've been balling around this idea now and i know how it works, but i'm having a really hard time thinking of a simple and clear way of putting it into code. It could be that i'm just extremely tired, but i'll try my best, i'll update you in a PM, or just a reply, if i get something written that's even close to decent. Thanks again for everything and taking the time to help me. :P

[TarikNeaj]

Having a good idea on how it works is a great start, putting it to code is the challenge. Give it a day of trying and we'll see how you progress. If you feel you've done your best and is at a point where you're clueless, you can pm me and I'll help you in person via skype or something if you prefer it that way. Goodluck =)

P.S. You'll also need to active the ability to be PM'd.
