I have been trying for a while to copy a string to an array, i know i can copy an char_array element to a string but its with a two dimension. How can i do this? i want it to be user entered.
I am trying to copy a string to an array of string. I have used these two examples before and they have worked so I don't understand why they won't work this time. I am getting a segmentation fault.

I remembered to initialize everything.
char *strings_mneumonic_table[503] = {0};
char mneumonic[20] = {0};
int start_address = 0;
int hash = 0;
if(line[0] == 32)
[Code]...
Here is my output
hash is 2
little start
BIG START
32 group
mneumonic is START
hash is 2
Segmentation fault (core dumped)
I have this function in a class: and a private declaration: how can I copy the parameter "ProductName" to allowedProductName. I tried all combination and I can't get it to compile.
private:
StatusPanel &statusPanel;
char allowedProductName[MAX_NAME_LENGTH];

Copy some characters from char * arg to char * first using a loop with specific conditions.
Code:
char * arg;
// set arg some string...
char first_[25];
char * first;
int length;
length=strlen(arg);
for (n++; arg[n] != '}' || n>=length-1; n++)
strcpy(first,arg[n]); // first += arg[n]; I have strcpy(first,arg[n]); but arg[n] is char and strcpy expects char * ;
how to solve this?
My goal is to copy only the elements of string 2 that are equal to string 1 into a new string. I tested this idea with an array of integers and it worked, but didn't work for the strings.
Code:
#include<stdio.h>
main()
{
int scan1;
char arr1[40] ;
char arr2[40] ;
char arr3[40] = {'_',.....,'_'}; /*for sake of brevity with post*/
}

I have one tab seperated file and i whish to change values in one column and then copy the entire row (including the changed value) into anothe file.
file :
Code:
x y z sdfsdgnsdfgndfjgndfbsgdf
x y z dkjfgdsbfvgsdfvg
x y z ksdnfsdfbsdnfsdvjsdbvjsdjfnsdbfubsdfjsdbfuibsdfsdfujbsduf
the way i am doing it right now:
Code:
while (fgets(line, sizeof line, list) != NULL){
result = sscanf(line, "%ld %ld %d %10000s", &one,& two, &three,string);
if (results == 4){
// change three
//print: one two three string
}
}
the problem is that the string in the file is of variable size and sometimes it is bigger then my char string[10001] array which then i need to resize and it gets messy. Is there a way to somehow , once identified first three numbers (and modified) just to read the rest on a character base and the print it character by character into a new file so that i can avoid string array completly.
I am getting an error when i try to open FILE which user must enter then program must open that file i an function and copy string from that file in other .
Error is expression (stream !=NULL)
insert Code:
#include <stdio.h>
#include <stdlib.h>
void FileCopy(char a[],char b[]);
void main() {
char a[40],b[40];

i'm right now using C, IO is done via ncurses, but that won't affect the following problem, i think. The relevant code is:
#define SIDEBARWIDTH 27
//...
typedef struct {
[Code]...
surprisingly this works, now the new 3rd outputline is correct again. So it seems that the printcommand has some troubles with accessing the struct here. Not sure if that might be ncurses fault. Still feels odd.
I am trying to write a program that takes a sentence and reverses the word order.
For instance This is a Bird would become Bird a is This
Code :
#include <stdio.h>
#include <string.h>
#include <ctype.h>
int main (void) {
char input_buffer[1024];
char middle[1024];
[Code] ....
But it can the other way around
Code:
static_Array= dynamic_Array;
dynamic_Array = static_Array;
The second statement works and i'm able to print out both arrays with equal values but with the first
[code] static_Array = dynamic_Array;I get incompatible types in assignment of 'int*' to 'int [7]' is the error I get [/code]
I want to copy the middle of 2dim array into another array. who knows how i can do it. for example I have:
int A[4][2] = {{1, 2} ,{5, 6} , {7, 8} , {3, 4} };
copy the second and third rows into another array to have the following array:
int B[4][2] = {{null, null} ,{5, 6} , {7, 8} , {null, null} };
I have written this code, and at first glance it does what I want, however I am worried that
a) I am overwriting the array that is apssed from chord.getPattern()
b) Im getting a memory leak that I want to get rid of, and
c) is there generally a /what is the neater way to do it:
Code:
uint8_t* ChordBuilder::invert(uint8_t count, Chord chord) {
temp = chord.getPattern();
chord.invert(true);
//TODO count is how many times to invert. Moves root aswell however
for (uint8_t i = 0; i < count; i++){
[Code] ....
temp is a member variable of ChordBuilder - and is expressed as: Code: uint8_t* temp; I dont want the pattern that chord stores, and passes with getPattern() to change - I fear it is at the moment?
I would rather not use the "new" but I cant think how to get rid of it, however Im not sure where I would need to put the "delete"?

I am trying to figure out copy constructors for a dynamic array and I am definitely missing something. If I go into the copy constructor routine during debug, the values appear to be correct but they don't percolate up to the newly created object. I'll post a portion of the code below:
Code:
// include header files for the classes that are being used
#include "stdafx.h" //
NOTE: THis reference must be added to all cpp files in Visual Studio Express 2013
#include <iostream>
#include <string>
#include <cstdlib>
#include <map>
using namespace std;
const int ARRAY_SIZE_DEFAULT = 32;
class vectorOfInt {
public:
[code]....
The size of c is 0. Values of a were not copied to c, although they appear to do so within the copy constructor routine.
Code:
#include<stdio.h>
void main() {
int x=0;
int y=0;
char c;
FILE* HUG;
FILE*fopen();

my question is located as a comment beside the last printf ! ? check the comment near the last printf the comment is ==>here i get a sequence of numbers the question is how can i copy this sequence to an array and the print the array out ?

#define N 30
#define n 100

I am trying to compare 2 strings of characters The users input containing 5 chars is compared to a table If the input is already be existent in the table the index of those chars in the table is printed Quest: how to copy the result of a printf() into an array ? The last printf() gives a sequence of numbers and I am trying to save that sequence to another array for further operation ! I have not been able to do that so far even with tmp[]=i ;

I am having some trouble performing this. I am not sure, if my unsigned char arrays are null terminated, but I don't think so. Here is my code: They are supposed to be byte arrays of size 16.
int setkey(unsigned char* ky) {
printf("INSIDE POLY-DEL ... key byte array passed in HEX:
");
int i;
for (i = 0; i < (int)16; i++)

I'm trying to copy my array 'block' to a 'dummy' 3D matrix so I can take out some arbitrary smaller matrix. Shouldn't this be possible with std::copy, where I'm certain the number of elements in the 1D array are equivalent to those in the dummy?
int dummy[210][210][1000];
std::copy(&block[0], &block[block.size()], &dummy);
I know everything works except my copy constructor! There are no errors. The program crashes when it goes to access the copy constructor. why the copy constructor isn't working?
#ifdef _MSC_VER
#define _CRT_SECURE_NO_WARNINGS
#endif
#include <cstring> // access to C str functions
#include "String.h" // access String class
using namespace std;
String::String( int size )// default constructor

How would i copy this array to a another array but have a different memory address so when i deallocate array a my copy array also isn't deallocated.
I am trying to write a program for a library system that allow stuff to add, remove, view and delete customer. i try to use file to store data and i open the file in mode read then i store then i put the content of the file into a structure. now the problem started it is only showing me haft of the content and here is the coding.
#include <stdio.h>
# include <windows.h>
# include <stdlib.h>
#include<string.h>
#include<conio.h>

I am trying to copy string Line BY Line from text file into array of pointers. lets say file has only two lines for example.
This is an apple.
This is another apple.
I want to copy both of these lines from file to array of pointers. Below is the code which i am trying to use for this.
Code:
#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <fstream>
#include <string.h>
using namespace std;
int main() {
char const *filePath = "test.txt";
[Code] ....
using the following header files:
Code:
#include <list>
#include <map>
#include <iostream>
#include <algorithm>
and
Code:
std::list
If there is a creation of a list, how can one find the sizeof the list. and is it possible to copy all the data from the linked list into an array. Assuming that the data is of type
Code:
char
Very new to programming, and I know that there must be another way on inputting a string into each array cells not by just inputting it one by one, but as a whole. My code at the meantime is: [URL]
