C/C++ :: Copy A String To Array Of String
Mar 27, 2014
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.
[URL]...
[URL]...
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)

using namespace std;
int main(){
char char_array[10];
int ascii_array[10];
[Code] ....
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 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*/
}
[code]....

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)

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];

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]

/*assume array is already initialized and declared and is of array type string.*/
int i = 2;
int j = 1;
string newvalue;
cout<<"Current value at array[i][j] is "<<array[i][j]<<endl;
cout<<"Enter new value "<<endl;
cin>>newvalue;
array[i][j]= newvalue; //PROBLEM IS IN THIS LINE.
cout<<endl;
cout<<array[i][j]<<endl;
I'm having lots of trouble with storing a cin string text into a string array. It just seem that after I cin newvalue, the program crashes. Is this way of storing it considered illegal? I'm just a beginner with 5 months of coding experience in C++.

I'm trying to "tokenize" a string using std::string functions, but I stored the text in a char array. When I try to convert it to a string, the string has the first character right but the rest is garbage.
// Get value from ListBox.
char selectedValue[256];
memset(selectedValue, NULL, 256);
SendMessage(GetDlgItem(hWnd, IDC_LB_CURRENTSCRIPT), LB_GETTEXT, selectedIndex, (LPARAM)selectedValue);
// Convert to string.
string val(selectedValue);
[Code] ....

Ok so I searched this site, and google string arrays, but I couldn't find anything on how to create an array to accept string input. In other words the strings are unknown, until the user inputs them..
so code would say input a name..user enters Tom, and its inserted into the array.. and if another name is entered ..lets say Lisa..Lisa is added to the array..so now in the array we have tom and Lisa..
Everything I read only shows the array already having the strings declared...
string n;
string name[n]={};

What is the efficiency of the two assignments (line 1 and 2), i.e. (function calls, number of copies made, etc), also the Big O notation. I know there are function calls for retrieving the size of each string in order to produce a new buffer for the concatenated string...any difference between line 1 and 2 in terms of efficiency?
String s("Hello");
String t("There");
1. s = s + t;
2. s += t;

Ok, so I'm writing this code and when I build it keeps saying cannot implicitely convert type int to string even though I declared my variables as string. Why is it giving me this error?
private static string Repair()
{
string result="";
string beep;
string spin;
Console.WriteLine("Does your computer beep on startup?:(y,n)");

I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code:
#include <stdio.h>
#include <string.h>
int main() {
char str[100];
int i = 0;
[Code] ....
Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0;
at the beginning of the code and then made
Code: count = strlen(str);
why wouldn't i have the same result? Is there a way to do it also?

I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main() {
string str = "3 J JD,K";
stringstream ss(str);
[Code] ....
Output of the code is
3 J JD
k
but I want
3
J
JD
K
Also after I split the string is there any way to put the split string into individual string variables.

In this code, i declared a string constant and trying to print the length of string. I know that if i write char a1[7] or char a1[] than it runs and give aggregate output, but in this case it is giving double length of string.
Code:
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
}

I wrote a program that reads a list from a file and stores it in a string type vector. Now, I want the user to input a word so that the program can search the vector to see if that word already exists. I have used every possible way of reading input from the console and storing it in order to compare with the vector but it never results in a match. When I print the input string and the vector string they are exactly the same thing (or at least print to the console as if they were). I've tried using getline; using cin direct to a string var; using cin to a char array and then casting to string using string str(arr); I even added a newline at the end just in case and STILL I cannot get a match.
vector <string> currentSet; //read a list in from a file and has 9 items in it
cin.ignore();
string line;
getline(cin, line);
if(line == vector[0]){//if printed to console line is HEAT and vector[0] is HEAT
cout<<"match"<<endl;
}

write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.) Does this follow the criteria? This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?
#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;
int main() {
char let[100];
cout << "Enter what you would like to be UPPERCASE: ";

I made a simple little program that takes text from the clipboard, and spits out all the lines I've copied one at a time (so my program can analyze it).
everything works perfectly, except, it spits it own in the wrong order, I want it to spit out from bottom to top. but currently it spits out the data from top to bottom. here is my code :
Code:
#include <iostream>
#include <Windows.h>
#include <string>
#include <sstream>
using namespace std;
int main() {
HANDLE clip; // assigns the var. clip to hold a handle ID.
[Code] .....
I want this loop to run backwards! Like it say's what I want to work backwards. Where as I know how to flip a while loop like this: while(x < 5), how to flip a loop like the one I'm using. how I can do this?

I have the codes for such a problem where, to create a program that counts how many times the second string appears on the first string. Yes it counts if you put 1 letter only, but if you put 2, it is an error. As an example. If the first string is Harry Partear, and the second string is ar, it must count as 3. Here's the code:
Code:
#include <iostream>
#include <conio.h>
using namespace std;
int main ()

I am stuck in this program, Be given a string of chars, where each single char belongs to the following alphabet: a..zA..Z0..9 (So, in the string there are only lowercases, uppercases and digits. No blank, no comma, ...). For every char of the given alphabet, count how many times in the string
1-- the char belong to a sequence of identical chars whose length is at least three (i.e.: in the string cc74uyrpfccc348fhsjcccc3848djccccc484jd for three times the character 'c' satisfies this condition)
Code:
#include<stdio.h>
#include<conio.h>
#include<string.h>
[Code]...
2-what is the longest substring of characters strictly rising interm of ASCII code(the following is greater (>) of the previous)
3- what is the longest substring of successive characters interm of given string rannge (i.e.: fhkjshdfruytyzABCDEfglsj => 7)
