C :: Storing Integers To Character Array?

Jan 30, 2013

I am creating a program and am having trouble with one part. The input file looks like:

Code:
2
3
Bill Jeff Steve
Linda Brittany Jessica
3 1 4
2 1 9
8 3 7
6 4 9
4 8 9
6 9 4

Where I am stuck is putting the numbers into the string array. For example, Bill's scores should be set up as Bill's scores should be set as

Code: bill_score = {3, 1, 4}

and when this code is ran

Code:
for (i=0; i<3; i++) {
printf("%s - ", men[i]);

C++ :: Reading Integers From File And Storing Into Array?

Oct 28, 2014

My main issue is that when I store just one value into a simple integer variable, it gives me a big negative number.

My goal is to store a file that reads like this into arrays:

2014 1 23
2012 2 15
2013 1 25
etc

Where I would have the first column in an array, the second in another and the third in third array since I am not allowed to use multidimensional.

C :: Program To Get Series Of Integers From A User And Storing Those Values Into Array

Feb 10, 2013

The problem deals with writing a program to geta series of integers from a user and storing those values into an array. Then use a function called selection_sort, when given an array with n elements, the function must sort the array from smallest to largest values.

I have code, and im trying to get it to compile but im getting these implicit declaration errors and conflicting types. Here is my code and the compiler errors.

Code:
Compilation started at Sun Feb 10 20:14:48

C++ :: Get Matrix Indexes From The Value

Oct 17, 2013

I have a 3x3x3 matrix with values hanging from 1 to 27.

The order is this: Code: m[0][0][0] = 1;
m[0][0][1] = 2;
m[0][0][2] = 3;
m[0][1][0] = 4;
m[0][1][1] = 5;
m[0][1][2] = 6;
.
.
.
m[1][0][0] = 10;
m[1][0][1] = 11;
m[1][0][2] = 12;
.
.
.
m[2][2][0] = 25;
m[2][2][1] = 26;
m[2][2][2] = 27;

Is there an easy way to compute the indexes given the value? For example, I know that the first index can be found by dividing the value by 9.0: Code: const int firstIndex = ceil(value / 9.0) - 1; What about the second and the third indexes? I couldn't find a pattern in the numbers, and I didn't want to iterate through the matrix (the indexes will be calculated many times).

The other option is to create arrays where the values will be indexes and the matrix indexes will be the values. I'm not sure if it is the best way though

Visual C++ :: Getting Indexes Information From SQL Server?

Jan 6, 2014

Trying to get table indexes information in SQL Server 2012 I identified a strange situation for one scenarion.I have a table that contains two indexes referenced to some fields: Field_1 and Field_3 mapped over int, null columns (the number means the existing field order into the table designed few years ago...).

I am trying to get information about these indexes like this:

Code:
nRetCode = ::SQLStatistics(hstmtAux, NULL, 0, NULL, 0, (TCHAR*)(LPCTSTR)strTempTable, SQL_NTS, SQL_INDEX_ALL, SQL_ENSURE);
if (nRetCode == SQL_SUCCESS || nRetCode == SQL_SUCCESS_WITH_INFO)
{
nRetCode = ::SQLBindCol(hstmtAux, 4, SQL_C_SHORT, &swNonUnique, sizeof(SWORD), &cbNonUnique);
nRetCode = ::SQLBindCol(hstmtAux, 5, SQL_CHAR, szIdxQualif, sizeof(CHAR) * 130, &cbIdxQualif);
nRetCode = ::SQLBindCol(hstmtAux, 6, SQL_C_CHAR, szIdxName, sizeof(CHAR) * 130, &cbIdxName);
nRetCode = ::SQLBindCol(hstmtAux, 7, SQL_C_SHORT, &swType, sizeof(SWORD), &cbType);
nRetCode = ::SQLBindCol(hstmtAux, 8, SQL_C_SHORT, &swSeqInIdx, sizeof(SWORD), &cbSeqInIdx);
nRetCode = ::SQLBindCol(hstmtAux, 9, SQL_C_CHAR, szIdxColName, sizeof(CHAR) * 130, &cbIdxColName);

[code]....

Becasuse SQLExtendedFetch() is deprecated I used SQLFetchScroll() but the behavior is the same from my interest point of view.

Usally, I get the right information about indexes but in one situation I encounte a strange behavior. It's about having a clustered index into a scenario.
When Field_1 is Non-Unique, Non-Clustered and Field_3 is Clusted index I get the right information.

But if the index Field_1 is Clustered and the Field_3 is Non-Unique, Non-Clustered I get no information about Field_1 index (eg. szIdxName and szIdxColName are "" and their length is -1 that means SQL_NULL_DATA). So, I have no Index information. Within while loop, with the next iteration I get correct information about the second index Field_3.

I'm not sure whether the problem is with SQLStatistics, the bindings or SQLFetchScroll (they all always return SQL_SUCCESS). It looks like a problem with the driver when the first index is clustered.

C++ :: Save The Indexes Of Multi-dimensional Arrays

Apr 8, 2014

I am working on the game of fifteen.Yes this is home work. I was wondering if it is possible to save the indexes of an element in a two dim array. I need to find the position of the space in the two dim array save it, find the position of the tile which is passed in as an int and swap the two if they are adjacent. Here is my code

Edit: I can do this by saving i and j in separate int variables but is there a more elegant way of doing this

int board[MAX][MAX];
void init();
void swap(int* lhs, int* rhs);

C++ :: How To Program A Hash Map System Where Each Key Have Multiple Values Under Indexes

Nov 13, 2013

How difficult would it be to program a hash-map system where each "key" can have multiple values under indexes?

For example: "Word" -> 45(index 0) , 67(index 1) , 12(index 2). What could I start with to program this or where could I find a pre-made system that does this?

C :: Storing Random Number Into Array

srand((unsigned) time(&t));
draw[i] = rand() % 50; //feeling could be a problem with this line of code :::::

}

is it possible to do this. i am trying to get 6 different numbers stored into 6 elements of an array . this is the piece of the code i think there is a problem with. ie my program scans the numbers and then crashes at this point so think it could be something to do with the commented line?

C++ :: Array Not Storing Values Properly

Jan 4, 2013

For some reason the integer array, arr[100][50], declared in main is not storing the correct values when passed through the function charArrayToIntArray.

I made an output right in the function to show how the array is not keeping the proper values, although when I output the array from within the loop in the function, it shows the correct values.

C++ :: Storing Different Digits Of A Number Into Array Of Int

Oct 9, 2013

The aim is : If i have a natural number [max 5 digits] (say) n=13579. Then a[4]=1, a[3]=3, a[2]=5. a[1]=7. a[0]=9.

I start with a[4]= n/10000 .. then n= n - a[4]*10000;

then a[3]= n/1000. .. n= n - a[3]*1000;

i.e a[i]= n/10^i .... n= n - a[i]*10^i;

To reduce code size i used a for loop. The code is free from any syntax errors.

Its the "output" that is weird. I enter 13579 and what the program process is:
a[4]=1 a[3]=3 a[2]=5 a[1]=8 a[0]=5

Same goes for other numbers too.. leaving the most significant digit , the rest digits are just out of the logic!!

I am using CodeBlocks 12.11 and compiler is GNU GCC compiler.

Here is the output window: [URL] ....

Here is the code:

#include<iostream>
#include<math.h>
using namespace std;
int main() {
int n,a[5],i,t,dec,divisor; // n: storing number; t: copy of n,

C/C++ :: Storing IPv6 In Character Array?

Jul 11, 2014

Its been too long since I have had to fiddle bits and I am coming up short.

Bottom line is the new IPv6 ip address representation is of the format:

xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx

These come to me as hex values for example:

2001:7D7E:0000:0000:111A:222B:333C:4444

I want to store this in a char array, of integers of size char_addr[16] where each byte represents the integer representation of each xx pair thus

char_addr[0]=32 (20) *note address above
char_addr[1]=1 (01)
char_addr[2]=125 (7D)
char_addr[3]=126 (7E)
char_addr[4]=0 (00)
...
char_addr[15]=68 (44)

So I am having trouble filling that char_addr array.
