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]);
[Code].....

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.

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.

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

I am reading data from a text file into a program. I am well aware of the subtle distinctions in the mode of data input/entry when using the stream extraction operator, the get() function, and the getline() function.
My problem is that all of them do not read and/or store the newline character alongside the data read!
Any function that reads and stores data and the terminating newline character together??

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";

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?

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,

The program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?
Code:
#include<stdio.h>
int main(){
char str[50];
char rev[50];
printf("Enter Desired Text: ");
scanf ("%[^

Is it just my compiler?

Objective: Write a function with the given signature that will take a sorted array of integers and return the array compacted. That is, given an array containing: 1, 2, 6, 8, 8, 8, 9, 10, 10, when the function returns, the contents of the array should be: 1, 2, 6, 8, 9, 10.
Restrictions:
Cannot use Distinct method
Signature:
public static int[] CompactArray(int[] input)

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.
