C# :: Output Two Dimensional Array With Proper Formatting
Jan 23, 2014
I have a 3x3 array which is filled up of random numbers, the limit being set by the user. So if the user chooses 3, the array will be filled up of 1s, 2s and 3s randomly. That bit is fine.
So when I display the array I use:
Console.WriteLine("
The values in the 2 dimensional array are: ");
foreach (int number in twoDimensional)
Console.Write(number.ToString() + " ");
The output will then be 3 3 2 1 3 1 2 3 3. Is there a way I can display it like:
3 3 2
1 3 1
2 3 3?

I have an array of strings and a two dimensional array made up of floats. In the output for the strings (this array stores 10 divers numbers) I am getting only 8 of the numbers, then a core dump. What could cause this?

How can I concatenate two 2-dimensional int arrays into one larger 3-dimensional array. This question is also valid for the 3-dimensional vectors. I know the command for the one dimensional vector as:
std::vector<int> results;
results.reserve(arr1.size() + arr2.size());
results.insert(results.end(), arr1.begin(), arr1.end());
results.insert(results.end(), arr2.begin(), arr2.end());
and for the one dimensional array as:
int * result = new int[size1 + size2];
copy(arr1, arr1 + size1, result);
copy(arr2, arr2 + size2, result + size1);
But I do not know how to make a 3-dimensional array or vector.

I had a hard question in my C++ final exam and I'm trying to solve it for the last 3 days. I haven't succeded yet! Here is the question: You have a one-dimensional array A[20]={1,2,3,4,...,20} and B[5][4] you have to assign the A array's elements to the B array but there is an order which is: B[5][4] = { { 12, 9, 11, 10 }, { 14, 7, 13, 8 }, { 16, 5, 15, 6 }, { 18, 3, 17, 4 }, { 20, 1, 19, 2 } } and there is a restriction: you can only use ONE for statement, nothing else!
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
int A[20] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,
16, 17, 18, 19, 20 }; // define A array's elements.
int B[5][4] = { 0 }, k = 1; // define B array and k counter.
[code]....
I can't narrow the statements to one,This program works perfectly but it shouldn't be that long, we need ONLY ONE FOR statement, not two!

class myclass{
string myarray[5];
myarray[0] = "one"; myarray[1] = "two"; myarray[2] = "three"; myarray[3] = "four";
myarray[4] = "five";
};
this works in main function but doesn't work in the class;
1. Why this methods doesn't work inside class but works in main function?
2. What is the proper way of using string array inside a class?

is it allowed to to like this:
char a[10] = "Lizard";
char b[2][5];
b[0][0] = a[0];
b[0][1] = a[1]; etc?

I have a 3D array that contains 200 strings. I'm trying to copy all these strings into a 2D array. How can this be done? This is what I have so far but it isn't working correctly.
Code:
for(int i = 0; i < row; i++) {
for (int j = 0; j < col; j++)
{
dest[i][j] = source[0][i][j];
} }
The finished product would be with 100 rows, 2 columns.

I want to create 2 functions to (1) convert a passed string into proper case (capitalize the first alpha character of a string and every alpha character that follows a non-alpha character); (2) sort the array of names (after it has been converted to proper case).
I tried these two:
console.writeline (lower.toUpper());
void bubblesort (string array[],int length);
but I don't know if they are good.

My problem is that the setfill('0') doesn't affect the output; I want four columns of 64bit numbers in hex which I read in binary mode from a file.
Here is the problem:
fffffff2 f1040000 fff10000 780000
76000d 11740000 0 5f
5f40405f 50636853 796d5f40 30304055
66687669 68556867 76657655 776c7866
and the code to produce it:
cout << hex << setw(4) << setfill('0') ;
unsigned long test,inc,grp;
grp = 0;
for (int i = 0; i < size; i += 4){
test = buffer[i];

I am using CRichEditCtrl in a dialog. I want to have auto wrapping off and paragraph justification as center or right. To turn off auto wrap i used SetTargetDevice which worked fine but the justification changed to left automatically. I tried to use SetParaFormat after setting the SetTargetDevice but unable to make the justification center or right when auto wrap is off.

I'm trying to write a short program that takes the input from a user and trims any leading/trailing white space, and then checks how many words are in the string. Problem is, I'm only allowed to use stdio.h and stdlib.h. How can I accomplish this? Also, how would I check if any of the characters which were entered aren't either a number, letter, or '-'?

Write a program using user-defined function which accepts an integer array and its size as arguments and assign the elements into a two dimensional array of integers in the following format: If the array is 1,2,3,4,5,6, the resultant 2D array is
1 2 3 4 5 6
1 2 3 4 5 0
1 2 3 4 0 0
1 2 3 0 0 0
1 2 0 0 0 0
1 0 0 0 0 0

I want to make a program that asks the user for a message and then print out a large graphic of that message. For example, if the user types "he" I want to print out
H..................H EEEEEEEEE
H..................H E
H..................H E
H..................H E
HHHHHHHHHH EEEEEEEEE
H..................H E
H..................H E
H..................H E
H..................H EEEEEEEEE
(treat the periods as spaces. I only put them there because it wouldn't separate the H's correctly.)
I will loop this to continue until the user types quit.
1. How would I set this up to store the user input characters into an array?
2. How would I print out the stored data in the shape of the word?

Consider the following code snippet:
GLfloat box[4][4] = {
{ x2, -y2, 0, 0 },
{ x2 + w, -y2, 1, 0 },
{ x2, -y2 - h, 0, 1 },
{ x2 + w, -y2 - h, 1, 1 },
};
Do I need to call a variant of
delete [] box;
Against this float array?

Here is what I have, I have a 1D Array being added to a 2D Array and I need to Sort them by value value 3 in the 2D Array, while maintaining a specific amount. Here is what I have so far:
public static void CheckHS(string[] HS) {
try {
GeneralData.HighScores[10, 0] = "11";
GeneralData.HighScores[10, 1] = HS[1];
GeneralData.HighScores[10, 2] = HS[2];
GeneralData.HighScores[10, 3] = HS[3];
//Need Sort Data - Bubble Sort?
}//end Try
catch (Exception ex) { MessageBox.Show(ex.Message); }
}
I am thinking bubble sorting but I remember reading about something faster. Unfortunately I can't find it on the web. The idea is that there will be always 10 Values and 4 Columns on the 2D Array. [The 11th Row being empty at the end of it.

I want to create 4 dimensional array, in that first three dimenstional are fixed size and the final index will be on 0 to N-numbers.
E.g., double array[500][25][10][<NOT FIXED>].. So I cant create statically, because the index size are more. Also I have tried 4 dimenstional vector, but its giving 2 problem.
(i) I am storing 4th dimenstion size is more than vector[0][0][0].max_size()
(ii) Storing and Retrieving its more time in vector
So, any other solution to store large array which is 3 index is FIXED and final one is not FIXED?

i created a program which uses Sparse 2 dimensional array, but i am not sure if i did it in the right way .
this is the instruction i have:
Create a constructor and a destructor. The constructor should take as input the size of the array (consider only square NxN arrays, so only one dimension is needed) and the thickness of the ribbon. To make this precise, if supplied with a thickness parameter t, you may assume that the element [0,t] (i.e. the (t+1)-th element of the first row) is where the useless area begins on the right. Similarly, the element [t,0] is where the useless area begins on the left. The border of the useless areas moves diagonally down and to the right, i.e. it consists of [1,t+1],[2,t+2],... and [t+1,1],[t+2,2],... The above example has thickness 3.
The space for the 2-d array should be dynamically allocated and must be large enough to fit the useful data only.Create methods for random read and write access to the array as in the case of 1-d arrays.Overload the [] and << operators, as in the case of 1-d arrays. Think carefully about what the [] operator should return and how it should work. Ideally we would like this to behave in a manner similar to standard 2-d arrays (i.e. accessing elements in the normal way, like x[5][6]).

This code shows a loop inside a loop initializing a two-dimensional array named arr with elements [2] and [5]. Here's my code:
Code:
#include <iostream>
#include <conio.h>
using namespace std;
int main ()
[Code]....
Now, what I wanted to do is to have an output showing the sums of each elements. Example, the above code has an output of:
1 2 3 4 5
6 7 8 9 10
I wanted to have more codes which would add up the elements 1 + 6, 2 + 7, 3 + 8, 4 + 9, 5 + 10 and produce and output:
7 9 11 13 15

I have a 10x10 array, initialized to all zeros. I create 2 random numbers for the purpose of guessing a position in the array.
However, when I print the array, the 0,0 spot keeps shifting to match the 2nd random number generated. Is there something strange about the 0,0 spot?
Here is my code:
Code:
seedrnd();
for (x=0;x<2;x++) {
randArray[x]=rnd(10);
}
for (x=0;x<2;x=x+1)
[Code] .....
The 2nd to last print statement actually prints randColumn. The last print statement correctly prints 0.

Code:

int col, row;
int *imageArray = (int**)malloc(row * sizeof(int*));
