I have the structure defined in the code below and need to insert a new string into the middle of the string array. I know there is a way to insert a new element with a vector. How to do this. I have tried several variations similar to uniqueList.word.insert(400,"disisdabomb"); but with no luck.
const int maxWordCount=1500;
struct wordCountList
{
string word[maxWordCount];
int count[maxWordCount];
};
wordCountList uniqueList;
I want to insert an element into binary tree using pointer passing through functions. In my program i have used three structure which are follows :-
Code:
struct tree{
int data1;
struct tree *leftptr;
struct tree *rightptr;
};
struct list{
struct tree **data;
struct list *node;
[Code]...
Here i think problem is in allocating memory to n2 . why i do this because i want to store the address of address of left and right pointers of tree and extract that address to get the address of left and right pointers. Is my method correct ?
I'm trying to code the program that will store item data.And I'm having problems to receive user-input string to array.

how can i compare an element of the char array and string with single chsracter also how to compare char array to cpp string
View 3 Replies View RelatedI have a pointer to a C string that contains multiple lines of text. I need to change a few characters in the string (possibly adding 1-2 extra). At the moment my code looks like this (char **objectData is the pointer):
Code:
char temp[350];
char* end = strstr (*objectData, "word_before_data_changes");
strncpy (temp, *objectData, 39); // Copying the first 39 symbols
strncat (temp, "6-11", 4); // inputting some data
strncat (temp, end, 100); // copying the last symbols.
I don't know how many there would be. Tried sizeof(end), but this cropped off last two lines for some reason. So using 100 at the moment. This sort of works, but I think it also adds some new lines or null-terminating characters in the end or something like that, because data parser cannot parse the modified data after that.
I'm trying to make a function that lets me pass an index and a string and will insert the string at that index in the linked list...
Code:
typedef struct node {
char* value;
struct node* next;
} LinkedList;
void llAddAtIndex(LinkedList** ll, char* value, int index) {
[Code] .....
#include "stdio.h"
char t[16] = {0x8F,0x78, 0xC6, 0x12, 0xBA,0x98, 0xA2,0x16, 0x8F,0x78, 0xC6, 0x12, 0xBA, 0x98, 0xA2, 0x16} ;
char w[44];
void main(){
for(int i=0 ; i<4 ; i++){
w[i] = (t[4*i], t[4*i+1], t[4*i+2], t[4*i+3]);
printf("%0x ",w[i]);
}
}
i want to put some elements of the t array into the w array but when i do this, it prints only t[4*i+3]
i want the output to be something like this
w[0] = t[4*i], t[4*i+1], t[4*i+2], t[4*i+3] = 0x8F,0x78, 0xC6, 0x12
w[1] = 0xBA,0x98, 0xA2,0x16
and so on
For some reason, my input seems to lag one behind when inserting data. Attached, I have code that I wrote along with the example of the lag. What may be wrong with my code that is causing this to lag?
View 7 Replies View RelatedBelow is an extracted portion of an example exercise from the C Programming Language book:
Code:
void escape(char * s, char * t) {
int i, j;
i = j = 0;
while ( t[i] ) {
switch( t[i] ) {
[Code] ....
Here's my problem with this. s is a pointer to a char array. That means each index stores 1 byte. A backslash character '' is one byte. In above example, we escape it with a second backslash character: ''. That means we have two bytes there. So why does it allow inserting two bytes into a one byte index?
i am working on creating a priority queue, i seem to have done the algorithm for inserting from the top correctly but the algorithm for inserting from the bottom doesnt seem to work it just overwrites the existing data.
below is my code :
list is an array and listlength is the size of the array declared as a integer
void inserttop(string task) {
//int head = 0 ;
string temp ;
listlength++ ;
for (int i = 1; i < listlength; i++) {
[Code]...
Code:
#include <iostream>
#include <string>
using namespace std;
int main() {
string s="Last Assignment/n";
cout<<j[1]<<j[2]<<j[3];
I don't understand how it printing each element of whole string. Like L a s. But I did not declared array.
Why I cannot do this to display each element of my char string? What is the proper way?
Code:
char str[SIZE];
int i;
for(i=0; i<SIZE; i++)
{
printf("%s", str[i]);
}
So I have linked list and function which deletes element if next element is bigger, so my code is working but its not working with first element, in the comment I have wrote code which I would code for checking that first element, but when ever I check it is blowing up all program.
#include <iostream>
using namespace std;
struct llist {
int x;
llist *next;

My code has been acting odd. I made a function that layers my art resources but only the last tile of my art resource acts the way it should. My character goes behind and in front of the last tile and gets printed correctly. Strangely its really exclusive to the last tiles I print. What I need is to figure out in step by step order what going on with my code sample below and be able to layer the resources.
Here is a small sample of my main function. This is how I do my rendering.
Code:
Int main (int arc, char* args[]) {
//Move class
Move character;
//Class Tile & Side Tile
Tile *tiles [TOTAL_TILES];

I want to a C program to delete an element from an array which can use both index method & character method
For example
input : "1 222 333 4444"
output:"1 22 333 4444"
if either index = "4" or character ="2" is entered
It should able to read in/accept any input array of varying length, and the position/index or element in array to be deleted...
how to delete an element(s) from an array; suppose I have an array x[10] = {1,2,3,4,5,6,7,8,9,10}, and I want to delete array{5} so that the values of the array become {1,2,3,4,5,7,8,9,10}; how do I go about this? This is not the same as setting the value of array{5} to null; but completely eliminating it so that it does not get printed alongside the other elements of the screen.

How would I go about having a pointer to an array element specificity a character in a c-string.Every thing I try will not even build.An array is already a pointer to the first location of the array right?
char *pHead;
char *pTail;
pHead = sentence[0]; <=== This wont build
pHead = &sentence[0];
pHead = sentence[0]*;
*pHead = sentence[0]; <===== this builds but is not storing anything
"Write a program in C that finds the element of an array which all the previous are smaller and all the next are bigger than that.If there are more than one print the biggest. If there isn't any print "ERROR" .
EXAMPLE
If the array has 10 elements like this : {2,3,4,6,5,7,8,10,9,8}
The correct answer is 7 , because 2,3,4,6,5 are smaller than 7 and 8,10,9,8 are bigger than 7.
I am working on it for 2 weeks and I can't find a working solution />/>/>

Above you said to find the middle value you should divide the array by two and then display the middle value (aka the median). For example, for an array consisting of 1 2 3 4 5, 3 would be the middle value.
My question is, how/what do I write to tell the program to display the middle value???
So far, I have done enough research and written enough code to receive values from the user and sort the array in ascending order. I simply don't know where to go from here (I started C++ about 1 month ago). I don't know how to tell it to pull the middle value.
I've researched "find_if", "nth_value" and a boat load of others with no luck
Here's what I've done so far:
#include <algorithm>
#include <functional>
#include <array>
#include <iostream>
[Code]....
How to shorten it but it would need the user to set a variable's value and use that variable to call the array element.
int main() {
const int size = 3;
int choice;
