Visual C++ :: How To Write Array Into 3 Different Arrays - Odd / Even And Negative

Jan 11, 2014

Place the even lucky numbers in an array called evenList, the odd lucky numbers in an array called oddList, and the negative lucky numbers in an array called negList.

//So in main main i passed the array as parameter and the size;

void lucknumberlist(int favnum[], int size) {
int even = 0, odd = 0, neg = 0;
int evenArray[even];
int oddArray[odd];
int negArray[neg];
if(favnum[even] % 2 == 0) {
evenArray[even] = favnum[even];

C :: Calloc For Array Of Array With Negative Index

Oct 14, 2014

I have an array of array with negative index. It is an array which has real dimensions [dim_y + 40][dim_x + 40] but the user uses the array like it has dimensions [dim_y][dim_x].

So i see the array's rows lets say from -20 to dim_y + 20 but a user sees only from 0 to dim_y.

First i had global and already defined the dimensions dim_x, dim_y, so i had this:

Code:

int map_boundaries[dim_y + 40][dim_x + 40];
int (*map)[dim_x+40] = (int(*)[dim_x+40])&map_boundaries[20][20]; In fact, 'map' points to 'map_boundaries' , map[0][0] is map_boundaries[20][20].

I did what is posted in the second post here: Negative array indexing - Everything2.com

I want 'map' to be global. Until now i had defined the dim_y and dim_x so that worked fine.Now i just need to read from a user the dim_x and dim_y.

Until now i have global

Code: int **map_boundaries;

and then in main i use calloc:

Code:

map_boundaries = (int **)calloc(dim_y + 40,sizeof(int*));
for(i = 0; i < dim_y + 40; i++){
map_boundaries[i] = (int *)calloc(dim_x + 40,sizeof(int));}

but i dont know how to declare this line now:

Code: int (*map)[dim_x+40] = (int(*)[dim_x+40])&map_boundaries[20][20];

C++ :: Write A Function That Receives Two Arrays Of Integers

Feb 19, 2013

There is one question :

Considerint A[10]={ ....................}; // already filled
int B[10]={ ....................}; // already filled

Using PIONTER NOTATION ONLY, write a function that receives two arrays of integers like A and B above. The function should swap the values in A and B. You may NOT use array notation [ ]. Also, you have to use pointers to move among array cells. Note: Both arrays are of the same size, and size should be variable in the function.

C :: Ignore Negative Numbers In Array

Feb 15, 2014

So i have this program that takes in user input and stores them into an array and then prints them, removes duplicates, and sorts in ascending order. The user can also stop by inputting a sentinel value (in this case -1). But i am also supposed to ignore any negative value besides -1. When i input any other negative value into the program it messes up. How would i go about ignoring the negative values?

Code:
#include<stdio.h>
int main()
{
int input, nums[20], i, j, k, temp, count=0, count2=0;
for(i=0;i<20;i++)

Nov 8, 2014

I need to ignore negative values in an array, but not exit the function.

For example if the user enters:

the array would be

[1,2,3,4]

Is there a way to ignore these values?

C# :: Convert Dictionaries To Arrays To Read And Write Sequentially

Nov 27, 2011

Code:

// declare child arrays
public string[,] childcolor;
public string[,] childgeneo;
// create dictionaries
public Dictionary<string, int> colors = new Dictionary<string, int>();
public string color; // name for dictionary
public Dictionary<string, string> geneo = new Dictionary<string, string>();

[Code]...

I'm getting "field' is used like a 'type' error on jw.childcolor which causes other parts to error out.

How do I fix this & why am I getting the error?

I want to convert the dictionaries to arrays to read & write sequentially.

Visual C++ :: Read And Write XML?

Sep 8, 2013

I receive a telegram in XML format and I need to parse it and send my data in the same format back. My main problem is that I'm not allowed to use any open source software or other 3rd party software except VS2010. I have to write it in C++.

Now my question: is there any good tutorial for such a parser? I was hoping that I could write something which can be used similar to the GEtPrivateProfil-functions which are handy for ini-files.

My XML telegram looks like hat:

Code:
<Tag0 cmdId=“254“ version=“1“ ID=“87951“ action=“doing1“>
<!—comment1 -->
<Tag1 lId=“31“ type=“12“ index=“100“ state=“open“ />
<Tag1 lId=“31“ type=“12“ index=“135“ state=“open" />
<!—comment2 -->
<Tag2 lId=“42“ type=“32“ index=“2“ state=“open" >
<param key=“pos“ value=“center“ />
<param key=“car“ />
</epr>
</Tag0>

I was hoping to find a way to get to know how many tag1 and tag2 are in tag0 and then get for each tag the attributes and sub-tags like param in tag2

Visual C++ :: Read And Write Values Into File?

Sep 22, 2012

correct the below code:

file already contains entries : 1st row username; 2nd row password.

check status required to write at third line and need to read or alter the check status value.

Currently this code is working if already there is a value for check status, then it is overwriting else UI hanging.

Code:
WriteCheckStatusToFile(BOOL& locVar) {
FILE *l_pFile = NULL;
CString l_strRememberCheck;
l_strRememberCheck = GetExePath() + _T("password");
CString sVar;
sVar.Format(_T("%d"),locVar);
