I have a struct called Array and I'm to create a function to create a dynamic array that's fill with randomly generated integers from 0 to 50 (inclusive) and a function to destroy the array for freeing its memory. Below the code that I have written so far.
Code:
* Struct */
typedef struct {int *pArray; //the dynamic array
int length; //the size of the dynamic array}Array;
/* Function to create a dynamic array */
Array *initializeArray (int length) {int i;

I got this program to create an array of playing cards and assign the values and suits and shuffle the array. I'm at the point where I need to output the cards but I need to burn the first card by making it output "**" instead of the card. my cards[] is a constant so I can's assign the first card as such.
void showCards(const int cards[], int numCards, bool hideFirstCard) {
if (cards[0]) {
hideFirstCard=true;
cards[0] = '**';
} for(int a = 0; a <= numCards; a++) {
cout >> showCard(cards[a]);
} }
I am trying to see if I can create an array of nodes. I think I have it down somewhat but this is what I have.

public:
int data[32];
bool selected = false;
person(){

I am trying to see if there is a way for me to create a 86 slot array of person nodes. I am not sure how to do it and how to access them afterwards. I know that I am creating the bitstring of person correctly but I am not sure how to get the array of person going.
Is it possible to create an 8 dimensional array in C? If no, then what can I do to improvise or let say bypass the limit?
View 7 Replies View RelatedI wanted to do this: Accept a line of input from user and save it to an array1 and copy its contents to other array in a set of arrays and then input another line to array1 and then copy it to next array in the same set and so on.... I know it is confusing but I can put it like that I want to create an array of arrays (Set of arrays). How can I do so?
I wrote a code to input the line in an array and tried to copy it another array of pointers, but pointers are just addresses so the same adress is copied again and again so, all the pointers of the array point to one address only. The code doesn't print anything when I try to print all the lines that were saved.
Code:
#include <stdio.h>
#include <stdlib.h>
#define MAXLEN 1000
#define MAXSIZE 100
int getline(char [], int );

What I am trying to do is to have the program create 2D array that for each row, no two numbers are the same and only consists numbers between 1-9. The array lists out every possible combinations. Supposely I do not know the number of possible combinations, I had it keep adding new rows until there are no more possiblities left.
The problem with my code is when I print out the completed array, it gives out really, really large numbers. But when I print the array from inside the first loop, it gives correct values. I do not know exactly what happened.
Code:
#include <stdio.h>
int main(void) {
int double_digit[1][2];
int a = 1;
int b = 1;

I have to create dynamic array, where each element of it points to some value. I know how to create dynamic array
Code: array_record * record_1 = (array_record*)malloc( (group!/(2!(group!-2)!)) *sizeof(array_record));
But i don't know how i create this case. for example what i want if array elements are:
Code:
index value value
0 01 -> 345
1 02 -> 457
2 03 -> 689
3 21 -> 634
so if i have value somewhere 01 match with 01 in this array it display 345. how i can implement it?
My assignment is use a 3D array to create an image. Use an array of the form arr[300][200][3]. For this homework, you need to use an array of the form arr[3][400][500]. It will have 400 rows and 500 columns. You need to first initialize the array as described in class and after that write the array to a ppm image file. When viewed using Gimp, it should display USM. The letters would be 200 pixels high and 100 pixels wide each. Use at least 15 pixels for the width of the stroke. Use different colors for each letter and a different color for the background.This is what I have so far.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void initialize(unsigned char a[][200][3], int nrows, int ncols, int nc);
void printAll(unsigned char a[][200][3], int nrows, int ncols, int nc);

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 working on a big program, and it involves character arrays. What I want my function to do is create a seperate array that consists of the same number of "*" as there are letters in the word from the text file. For example, if the word sarc was up, the function show make ****. This was my attempt at it. I managed to reach this far. I can only fit in one "*". This is part of jumble game program I'm trying to make, and its in C language.
insert Code: void partialWord(char current[]){
int n;
int i;
n = strlen(current);
for (i = 0; i < n; i++){
current[i] = strcpy(current,"*");
}
printf("%s
", current);
}

let's say I have an IntPtr that points to the raw data of System.Drawing.Bitmap. is there any way to create a byte array from that IntPtr without copying the data? I'm a pretty experienced C++ programmer, so I can call ToPointer() on it and convert to a byte* to work with it as a pointer, which is no big deal for me, but using a pointer and doing pointer arithmetic increases the risk of bugs, so I'd prefer not to do it that way if there's another way.
View 4 Replies View RelatedI'm writing code to create an array of integer and let user input choice to display, replace, add new element, etc.I created a header file in the header file there's a function:
Code:
int display_one_element(int* array, int num_of_elements, int position) {
if(num_of_elements < position || position < 0) {
printf("Position out of bound.

return 1;

in main I write a function call:

display_one_element(array, *p_num_elements, position);
My code seems to work fine but there's an error message right next to my function call:
1.too many arguments provided to function like macro invocation
2.Expression result unused
I tried to move the function from header file to c source file. but other functions in the header file works fine and this doesn't work with the error message.

I am trying to create an billing system "without using pointers". This is my class assignment. In this,
1) User inputs the name
2) The system asks how many items he has purchased
3) Displays a bill number [just a random number]
4) System asks for the item names the user purchased and stores them in an array (of max 10 (ten) inputs (or items))
5) After each item the user inputs, the system asks for the price of the item (stored in an array of numbers)
6) The total bill is calculated, by adding the sum of all prices in the array
I am having terrible difficulties in coding #4 and #5. Somehow, they aren't going well together. Here's what I have:

int price[10], total_item, total_price = 0, i, j, a, total_bill = 0, max_items = 10, max_char = 10;
