C/C++ :: Using Functions Storing Sequence In Array
Oct 4, 2014
Trying to make a program that stores a sequence of integers in an array by using functions. This is my code so far:
# include <iostream>
using namespace std;
int Sequence_Length(int seq_length)
{
[Code]....
I get an error in the main, not completely sure how to "call" functions to the main..

I am trying to write a program that checks whether the number is in sequence(as in if the numbers are in order it is a sequence). Ex: If the numbers are {1,2,3,6,7,8,9,10,11,13,15,17,20,21}, then, the underlined parts are a sequence. Now i want to find
1) the no of sequence in the array(in the above it is 3 )
2) the longest sequence (7to 11 which is 5).

At the moment im trying out with pointing to an array of functions. I got this working as following:
typedef void (* functionPtr) ();
functionPtr functions[2][2]={{do11,do12}, {do21,do22}};
void do11(){DEBUG_PRINTLN("11");}
void do12(){DEBUG_PRINTLN("12");}
void do21(){DEBUG_PRINTLN("21");}
void do22(){DEBUG_PRINTLN("22");}
void loop(){
A=0;
B=1;
functions[A][b]();
}
But now I'm trying to use this to point to a function inside a class so instead of do11, i want to be able to point to Basic.Do11. Somehow this doesnt work and I keep on getting this message:
error: argument of type 'void (Basic::)()' does not match 'void (*)()'

Take for example two arrays.
int A[2][2][2] = { {{1, 2}, {3, 4}},{{ 5, 6}, {7, 8}} };
int B[1]
I want to store the entire array "A" into B[1]. Is it possible?

I am having trouble storing strings into an array. Basically I have a console program where it has an option. This is just an example;
Code:
char name[max];
char listofnames[maxname];
int counter;
....
printf("Add names
");
And how can I print it?

How do I go about storing info to an array of class?I need to do something like this:
info[count] = ReadNameRating(n, r);
Where info is an array of my own class and ReadNameRating reads the name and rating which is two of the variables handled by that class.

I have a base class Building. Then come its children classes - Commercial Building and Residential Building. The third level is composed of Apartment and House classes, both inherit from Residential Building.
I need to create an array of 20 elements that will store info about all these different types of buildings(Commercial Building,Residential Building,Apartment, House). How should I proceed?

I want to create filenames such as Query.student.1.bin and save them in an array. I have no problem when I don't include a "." between student and number "1" but as I add a "." there my code does not run. ( it does complie but crashes during the run)
string *filename_str;
filename_str =new string[Number_X_Axis];
for(i=0;i<Number_X_Axis;i++)
filename_str[i]="Query."+Table_Name+"."+convertInt(i)+".bin";

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]);

Code:
for(int i = 0 ; i < SIZE ; i ++)
{
scanf("%d" , & selection[i]);
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?

Is something like this possible and if not how can I make this work?
fscanf(in, "%d %d %d", &i, &x, &arr[i+x]);

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.

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,

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.

I am unable to understand why is the output for this shows me the address of the stored array.

{
size_t k= 0 ;
char t[3][100] = { "hi", "di", "fi" } ;
char s[3][100] ;

I'm trying to read in a file and store it in an array that is dynamically allocated of a struct (which I'm not sure how to do), then parse each line using strtok() from string.h. The idea is to separate the lines by date, subject, time, etc.
Since the array is a dynamically allocated of typdef struct, it's sorted by the date of each struct, with an intial size of 25. But whenever the array needs to be resized, it should be doubled.

I have been dealing with this problem for quite some time, I've been assigned to develop a program that can store products' information within structures (the number of products is undefined). I thought I should use an array of structures, but I don't know how to declare it properly. This is what I thought would work:
struct product {
string name;
string in_stock;
float sale_cost;
int id; }
prod [n]; //n being the undefined number of products the user will register/delete/modify
I already saw an example of array of structures, but it uses a defined number.

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.

I just started learning about pointer and reference. * and &
The assignment is " Write a program that stores the following numbers in the array named miles:15,22,16,18,27,23, and 20. Have your program copy the data stored in miles to another array named dist, and then display the values in the dist array. YOur program should use pointer notation when copying and displaying array elements.
And this is what i have so far. But there is an error. I highlighted it with red. It says it's incompatible...
#include <iostream>
using namespace std;
const int arraynumb = 7; // declaration of keys: number of characters of keys
void copyfunc(int *[], int); // function initialized
int main() {
int miles[arraynumb] = {15, 22, 16, 18, 27, 23, 20};

I am trying to use C# with C++, two different applications that work together.
In C# it is easy to get a byte array out of a string, by just using Encoding.Default.GetBytes(of-this-string);
I can pass bytes to my C++ program by just writing in the embedded resources. But this won't allow strings, as far as I know it can only be a byte array. C++ reads the embedded resources a LPBYTE.
So I try to send the string or message in byteform.
However the problem in C++ is that there is no Encoding.Default.GetString(xxx)
Would there be any other ways to send a message/sentence in bytearrayform and request it in C++ back to the original string?

When declaring char array[10], memory is allocated for 10 1-bit memory locations. Is extra memory allocated for storing the address of array[0]? In expressions, is array equivalent to a pointer constant or is it an identifier for a memory cell containing the address of array[0]? In other words, is array a variable or an alias for &array[0]?

typedef client...I would like to have these fields filled with this function below and stored in an array... Basically Multiple users and this is my function for it, if I can get it to work proper -.- .... I don't get syntax errors but I do get warnings
Code:
void getct(client *cl, int *pclientCounter) {
char input[buff];
char *pinput = NULL;
int typef = 0;
int lengthf = 0;
