C++ :: Adding-up Elements Of Two-Dimensional Array?

Jan 9, 2015

I would just like to share my code and wanted to do something about it. This code shows a loop inside a loop initializing a two-dimensional array named arr with elements [2] and [5]. Here's my code:

#include <iostream>
#include <conio.h>
using namespace std;

[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

C :: Shifting Elements In 2 Dimensional Array

Feb 28, 2013

I am inserting elements from two files into 2-D arrays.Suppose I have generated this kind of code to create 2-D array:

Code:

main() {
int counter;
int divide=5, m1=0, l1=20, window=20;
for(counter=0;counter<divide;counter++){
for(i=m1,j=0;i<l1;i++,j++){
}

[code]....

Now after generating 2D array, if I want to shift last 2 elements from windata[counter] or winquery[counter] where counter=0 to the beginning of counter 1 and subsequently last two from counter 1 to counter 2 in this fashion, how can I do that.

C++ :: Adding Array Elements Together?

Sep 28, 2013

I'm having trouble getting my array to add its values together. I have a similar program running fine with the exact same equation. I am not so naive as to believe that this means it should run with every program but I'm at a loss as to what to do.

#include <iostream>
#include <iomanip>

C :: Adding Elements To Array Of Structs

Mar 6, 2015

I have a structure product_array *pa that contains a pointer *arr to an array of structs and count that adds 1 when a new product is added (set to NULL initially). I have to write a function which adds a new product entry to that array. One product entry has *title, *code, stock and price parameters. The array is dynamically allocated and I’m supposed to:

1. Reallocate space for array.
2. Update product_array.
3. Initialize it.

Also, code should be truncated to 7 characters.Products can be added multiple times, so the initial size is unknown.

Code:

void add_product(struct product_array *pa, const char *title, const char *code, int stock, double price)
{
for (int i = 0 ;; i++){
pa->arr = realloc(pa->arr, sizeof(struct product_array));

C++ :: Recursive Adding Elements In Array?

Mar 9, 2014

The goal of this program is to take 4 neighboring elements in an array and add them together. The program asks user for the number of rows and columns to start out with and the program will then continue to print the board until 1 element remains.

I'm having problems getting my program to compile (line 19)

#include <iostream>

C :: Array Of Structs (adding / Deleting Elements To A File)

Sep 20, 2013

I want to write a program to record my neighborhoods's name and address by using an array of structs and file.

my array of structs is

Code:
#define SIZE 30
typedef struct{
char name[30];
char address[100];
}Detail;
Detail neighbor[SIZE];

And I want to make adding,deleting, and searching functions.Something like

Code:

void add();//Add name and address to a file,
//and add more to the same file if I want to.
void del();//Delete or Change some neighbor's name or address
//in the same file(Can I?)
void search();//Search name and show detail

So I started to code adding function first, but I don't know that I need to use pointer to code each functions relations, and I don't know how to check that my input's already exists yet. But I started some code below...

Code:
void add() {
int i=0;
FILE *fp = fopen("neighborhood.txt", "at");
if ( fp != NULL ) {
do{

C :: Creating Two Dimensional String - Adding Char

Aug 15, 2014

I am making a program that formats a string. I want to create a new 2 dimensional string that will have many other chars and strings in it beside the original string. Then I split the string up on the newlines and return it. Adding different parts to the 2d string e.g. I need to add five _ as chars not string then I need to add different things. First I use sprintf () to add as much as possible. And then I do what to add the rest?

C++ :: Concatenate Two 2-dimensional Int Arrays Into One Larger 3-dimensional Array

Jul 31, 2013

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.

C++ :: Converting One-dimensional To Two-dimensional Array

Jan 17, 2014

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!

C :: How To Copy 3 Dimensional Array Into 2 Dimensional Array

Sep 2, 2013

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.

C++ :: 3 Dimensional Array Printing?

Oct 25, 2013

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?

C++ ::  Deleting Two Dimensional Array

Oct 21, 2014

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;

C# :: Sorting 2 Dimensional Array By Value

Jan 9, 2014

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.

C/C++ :: How To Create 4 Dimensional Array

Apr 24, 2013

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?

C++ :: Sparse 2 Dimensional Array?

Feb 26, 2012

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]).

C :: In Two Dimensional Array 0,0 Spot Keeps Changing

Jan 12, 2015

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.
