I am writing a code with C where I will give an integer and get the binary conversion of it.I tried to fill the binary digits into an integer array.But when I normally print it will give the proper output.But when I try to print the contents of the array it will not produce the proper result.
My code would be as follows.
#include <stdio.h>
#include <conio.h>
int main()

For the last part of this problem, if player 2 loses the game of hangman, I need to display the letters they did get right. In order to do that, I believe that I need to traverse vector v for the elements that exist in the string hiddenword, and then print those characters that match.
#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>
#include <vector>
#include <algorithm>
using namespace std;
int letterFill (char, string, string&);

I am trying to establish a connection between client and server to send a file to the server from a client. I have been successfully able to send files to the server but i am facing a problem with the the filename whenever i try to send any string to the server and use it in naming the filename at the server side, the string is successfully concatenated but it saves the filecontents in the filename.
for example: i am sending a file hello1.txt to server and the server has to save it as abcxyz.txt as i am sending the "xyz" from the client. BUT Whenever i am doing this ,the file saves as abcxyzfilecontents.txt If i saved in the .txt file "you123" ,my file at server side would save as abcxyzyou123.txt
Here are my codes:
Know that the server code implements a multi threaded server. The functionality to be discussed is defined in myfunc
Code:

I'm writing a program that stores records into a file and then these records can be printed out. A last name, first name, and score is stored to be exactly 36 characters long (using leading spaces to pad) making it easier to retrieve specific records. For example, three records stored in the file would like like this: (the underscores are simply to illustrate the distance, they are not in the file itself)
_______lastname_______firstname__90__________lname __________fname_100___________last___________first __60
When printed out, the names are formatted as follows:
lastname, firstname: 90
lname, fname: 100
last, first: 60
However, when I print them out this is what I get:
lastname, firstname: 90
lname, fname: 100$
last, first: 60H
For some reason, for any record after the first, an extra character is added to the end. These characters are not in the file, so I was thinking that the array for some reason wasn't being filled completely, (the array is initialized to size 36 and 36 characters are read from the file using fread) so it was printing out a random character assigned to the 36th array position. Except the character never changes, (always a $ for record 2, H for record 3, l for record 4 if i remember) and I've tried reducing the array size or the number of character read and it's the string that gets altered, the random character always remains. I figure the problem must be in the print_records function (appending seems to work no problem). Anyway here is my print records and appending records code.
Code: /*
- Prints a single record stored in the file pointed to by ifp.
*/
void print_record(FILE *ifp, int record) {

I'm trying to reverse 25 items that are in my array by using a For Loop and sending 2 of the numbers to a function at a time. The code I have right here, is not working at the moment, I cannot find the problem because i've been staring at my code for too long.
int farEnd = 24;
for (int i = 0; i < 24; i++){
Swap(intArray[i], intArray[farEnd]);
farEnd--;
}
Also here is the code in my function
void Swap(int num1, int num2){
int temp = 0;
temp = num1;
num1 = num2;
num2 = temp;

So I insert values from a vector into a list and into a multiset, and I noticed zero is added to their contents! I had to do a whole lot of debugging to find out where the error was, how can i stop this thing? Code which generates such error...
infact i checked the content of vector ups to be sure that there was no zero in it, but after loading into list combi_t * head, it seems like there was a zero added and this is giving me errors when i call function master_roller...
Code:
void ins(combi_t * &testa, int &numero, int &num, int &no)
{ // if (ricerca(testa, numero) == 0)
//{
combi_t *temp = new combi_t;
temp->val0 = numero;
temp->val1 = num;
temp->val2 = no;
temp->nextPtr = 0;

In the function *expandArrayList and *trimArrayList I need to allocate either more memory or less memory to the given array. Right now I am using malloc on a new array and then transferring the elements of the original array to the new array, freeing the original array, and then reassigning it to the new array so it's size and capacity are either bigger or smaller than the original. I feel like there has to be a simpler way to do this with either realloc or calloc, but I cant find sufficient information on either online. Would I be able to use either to make this easier and the code cleaner?
Also, these are character arrays that contain several character arrays inside them, so I was wondering what the best way to transfer the contents of one array to the other would be. I have gone between
Code:
//example
for (i=0; i<length; i++){
newarray[i] = oldarray[i];
}
and
Code: for (i=0; i<length; i++){
strcpy(newarray[i], oldarray[i]);
}
but I'm not sure which one (if either) should work.
The 'ArrayList.h' file that is included contains the structure ArrayList, as well as the function prototypes for the functions listed below.

So I am working on a FUSE filesystem and I currently have the need to load the contents of a text file into an array.
My array initialization looks like: char array[max_entries][PATH_MAX] = {NULL}
The reason I want to pass it by reference is that I want my function to return two values essentially. One a specific char* and the other an array like I initialized. My function proto type looks like:
char* load_meta(char* list[max_entries][PATH_MAX], char* path, int mode);
How I'm trying to call the function:
someChar = load_meta(&array, path_name, 1);
Within the function I try to edit the array by deferenceing it once, like this:
strcpy(*list[i], file_entry); // This seg faults
Is there some quick way of resetting the contents of an existing array to 0? Just to be clear, I'm not initializing the array, it already exists, has content and needs to be reset at 0. Is there a faster way than the code below?
Code:
for(i=0;i<100;i++)myarray[i]=0;

I'm coding a hangman game. I'm trying to store user entries so i can output them to show the user what they have already entered. Problem is that it's not display anything at all.
I'm trying to store multiple characters of course, and then display all characters stored.
char guess[27]={0};
cin >> guess[26];
int hit=0;
for(int i=0; i<len; i++) {
if( guess[26] == hidden_word[i] ) {
hit++;
select_word[i] = guess[26];
if(strcmp(hidden_word,select_word) == 0) {

EDIT: I also get the error - Stack around the variable 'guess' was corrupted. At the end of the game.
I am trying to store the contents of a text file into a char array. However the function i am using ifstream member function get(); seems to stop working when fed with certain characters. Is there another solution besides the get() function that will accept all types of characters from files?

for (int i = 0; i <= textlen; ++i)
{
text[i] = text_in.get();

I need to create an overloaded cout that will print the contents of an array. So I can say output << a << endl;
And it will print the contents of the object a... which happens to be an array.

bool empty(); //returns true of false if empty
void front(); //makes current position at beginning of list
void end(); //makes current position at the end of list

I understand this code, I am simply calling the size method from the program, but i don't know how to pass in the array so that i can print it line by line... simple syntax i am sure... but the whole thing is baffling me... I need to be able to call this on any variation of the class, so it cannot be specific to any one array.
I am trying to store a large text file into an array so I can count the number of characters.
View 2 Replies View RelatedI am unsure how to write a function which modifies the content of the 1D character array and puts all of the letter it contains into uppercase. the following are the letters which i am trying to convert.
char text[MAX+1] = {'T', 'e', 's', 't', 'e', 'r', EOT};
The output to this should look like T E S T E R EOT
Goal:
Read contents from a file and use as the size of a 2d array.
Problem:
C2087: Line 27 : "a1" : missing subscript
C2133: Line 27 : "a1" : unknown size
Code :
int rows;
int columns;
ifstream fObject("inputdata.dat");
fObject>>rows;
fObject>>columns;
char a1[rows][columns];
I am not sure why this is occurring, or if there is a better way to do it.

I want to make a program that asks the user for a message and then print out a large graphic of that message. For example, if the user types "he" I want to print out
H..................H EEEEEEEEE
H..................H E
H..................H E
H..................H E
HHHHHHHHHH EEEEEEEEE
H..................H E
H..................H E
H..................H E
H..................H EEEEEEEEE
(treat the periods as spaces. I only put them there because it wouldn't separate the H's correctly.)
I will loop this to continue until the user types quit.
1. How would I set this up to store the user input characters into an array?
2. How would I print out the stored data in the shape of the word?

I have an array of structure that takes family information (name, age, and state) after it takes the users input it prints back all of the information that was input and then prints the family members that just live in Texas. After that I am trying to implement a function to average out the ages of all family members but I cant seem to get it right, whenever it gets to that part of the program it just outputs 0. I also tried adding an & sign prior to FAMILY[i].age and got an error of int from ptr with no cast.
Also I realize that the code only shows adding of the family members ages which is fine for now as I am concentrated on getting that to work in the first place.

#include <stdio.h>

I'm having some trouble printing the duplicates found in an array. Specifically, when the value is at more than 2 positions. So if the value 3 is at position 1, 10, and 11 it'll print three messages instead of two:
value 3 at position 1 is also at position 10
value 3 at position 1 is also at position 11
value 3 at position 10 is also at position 11
instead of
value 3 at position 1 is also at position 10
value 3 at position 1 is also at position 11
This is real simple problem, but I can't seem to figure it out. I've been trying to implement another array to 'remember' the encountered position, but I haven't had any luck.
Code:
for(i = 0; i < num_count; i++){for (j = i + 1; j < num_count; j++) {if (num[i] == num[j]){printf("
value %d at position %d is also at position %d", num[i], i, j);}}}

I need to print all the values in a square 2d array that are above the diagonal line. So if I have this 6x6 array for instance:
{0,0,0,0,0,0},
{1,1,1,1,1,1},
{2,2,2,2,2,2},
{3,3,3,3,3,3},
{4,4,4,4,4,4},
{5,5,5,5,5,5}
I'd have to print the elements in italics. I've tried this:
for (i = 1; i < a.GetLength(0); i++) {
for (j = i-1; j >=0; j--)
Console.Write("{0,-2}", a[i, j]);
Console.WriteLine();
}
with the array mentioned above but for some reason it keeps printing the elements BELOW the line, when I need it to print those above it. I know that for arrays we usually start loops with a value of 0 but seeing as there should be nothing to print at [0,0] I started the loop at 1.
