C/C++ :: How To Declare Array With Undefined Size
Oct 7, 2014I need to make a program that will let the user input values and it will only stop accepting once the user has inputted a negative number then it will display its mode and frequency.
The problem is I can't find a way to let the user input values freely without asking first for the no. of values he will enter.
#include<stdio.h>
int main() {
int i,j,k=1,p,a[20],b[20],n,cnt=1,big;

C++ :: How To Declare Array With Constant Size Inside Of Class

Jan 13, 2015Problems :
1) Is there any way so that i can use "X" and "O" char instead of 9 and 0 int.?? I also tried to use enum but was only able to print out -1 for 'X' and 0 for 'O'...
2) if player - 1 choose field 2 . and player - 2 chooses field 2 .. how can i show error and ask for another input ?
3) is there any short coding trick for int check_result(); ?

C :: Pointer To Multidimensional Array
Jul 31, 2014What is the correct method of declaring pointer to multidimensional array

C++ :: Passing A Multidimensional Array
Sep 25, 2013I'm trying to pass a two-dimensional array to a function. The function is defined as: long foobar(char foo[][CONST]); I have to create that array dynamically. Currently I do that this way: char* bar = new char[count * CONST];
But when I'm trying to pass the array I get a type conversion error. I tried a lot of different ways to pass the pointer and/or to allocate the memory, but apparently I didn't find the right way or combination of definition, allocation, casting and calling.I cannot change the definition of the function, which (IMHO) is pretty stupid. :(

C :: Scanning Characters Into A Multidimensional Array
Mar 19, 2014I have initialized a multidimensional array eg char fruit[5][10]...Then I would need to read in 3 words with spaces in between from user and store in fruit[5][10] e.g "pear apple orange"
The thing is that after typing orange, when I press Enter it still prompts me to enter more characters. How can I end the scanning of characters after orange ?
C :: Using A Pointer To Parse Multidimensional Array
Feb 27, 2015I have a 3-dimensional matrix(3,3,3) and want to write it to a file. I have the code for parsing it in a compatible for matlab format. But at this point i want to use a pointer to do the same thing.
Code:
#include <stdio.h>
#include <stdlib.h>
int main() {
const int dimx = 3, dimy = 3;
int i, j;
unsigned char a[3][3][3] = {
[Code]...
If it is a 1-dimensional array i can understand the logic.
Code:
int val[7] = { 11, 22, 33, 44, 55, 66, 77 } ;
int *p;
p = val[0];

C++ :: Output Multidimensional Array Using For Loops

C++ :: Parsing Multidimensional Vector Into Array
Nov 30, 2013For a rather complex and strange reason that I won't explain right now, I need to have this going on in my program.
class FVF{
private:
vector<vector<float>> data; //Contains fvf data for Direct3D stuff
public:
[Code].....
The FVF allows this Model3D class to also be compatible with file handling methods I've got, but here's the problem. D3D buffers require an array to feed them the information, and I know that for a single dimension of vector I can use vec.data(), how to do this for multiple dimensions.
I think the best Idea I've got so far is to set the vector within the Model3D class as a pointer, then I can union it with a float pointer... Once I can guarantee the information is correct and complete, manually transfer the contents of the vectors into the float pointer.. (The union is to reduce memory needed instead of having the data repeated in vectors and arrays)
how I could just pass these as arrays?
C++ :: Loop Unrolling Multidimensional Array?

C/C++ :: Read Strings From File And Place Into Multidimensional Array
Mar 1, 2014I am having problems figuring out how to place a list of strings from a text file into a multidimensional array that is something like words[NUM_WORDS][MAX_LEN]. I already run through the file once and count the number of words in it. I have tried a number of loops using fscanf and fgets, but I'm not sure if I am using them right -- this is my first time using them. The text file is a list of words in a dictionary, so the wordCount is about 45340.
Here is my code:
#include <stdio.h>
#include <string.h>
#define MAX_LEN 46
int main(){
int wordCount = 0;
FILE *inputFile, *outputFile;
[Code] ....
Like I said, the wordCount portion works. I added the printf statements at the end to see if anything was being saved, but it just prints two new blank lines. New to file reading and writing.
C/C++ :: Read BMP Image Data Into Multidimensional Array Of Structures
Apr 8, 2014I am trying to read the information from a .bmp file into my program while dynamically allocating memory for all of it. So I defined the structures for the headers and for a pixel, and then I have to read each pixel into a multi-dimensional array of pixels. I am completely new to structures, and definitely new to pointers combined with structures. I will have to use a filter with the information later, but right now I just want to read everything in correctly. The array of pixels will be two-dimensional -- the width by the height of the image, I guess.
Here's my code:

#include <string.h>
