making my delete function work. My program does compile but my delete function doesn't work. I haven't finished my last two functions because I am focusing on the delete but how to Sell a title and print the value of all sold titles would be nice as well.

#include <cstdlib>

Here is the Method Code:
public void DeleteCustomer(string firstName, string lastName,
string address1, string address2, string city,
string state, string phoneNumber, int customerID)
{
[Code]....
.... And here is the response I get:
Error Deleting customer, please check form data. Syntax error in FROM clause.
int main() {
int vnum = 0;
VEHICLE *vehiptr;
VEHICLE *dptr;
cout<<"Please enter the number of vehicle: ";
cin>>vnum;
vehiptr = new VEHICLE[vnum];

I have to manage a Clinic. I need to delete a booking (for example, if John said he's coming on March 22nd at 15:30 but then he say he's not going to come, I have to delete that booking so another person can use it).
idSearched: the id of the person that is not going to come. I have a lot of specialties and each one has a list. So I ask for the speciality to delete the node (the node contains John's booking). If I don't find it, I return (-1). searchSpecByID return a pointer to the list where the speciality is. So head will point to the first node of the list. In nodeToDelete I have the node I want to delete.
The program detects OK when is the first in the list and when not, but it doesn't delete the node.
Code:
typedef struct bookingList{
tSpecialty specialty;
struct nodo* intro;
} tList;

How I can delete a parameter in a function .
int *buildTrail(int antIndex, int start, double *pheromones) {
int *trail = new int[tabu];
bool *visited = new bool[tabu];
trail[0] = start;
visited[start] = true;
[Code] ....
If I comment all lines includes visited word , no exception occurs , Otherwise , exception throws.
Simply put , How can i delete visited parameter as long as its role has been finished?
.
.
.
delete visited ;
return trail;
Code:
#include <stdio.h>
int main() {
int m,c;
for(c=0;c<100;c++) {
m = c % 10;
printf("%d ",m);
}
return(0);
}
When I run this code in my compiler, I get the first nine or ten numbers, and then after that it just spells out the letters in my name in different sequences over and over.
I am having an issue when i try to delete a node with 2 children it either doesn't delete anything, or wigs out in various manners deleting the wrong node or replacing a node with a various memory location. As follows, here is the delete function:
void BST::dele(){
bool found = false;//initialize a bool type to "find" the element to be deleted
if(root == NULL) return;//well if the tree's empty, nothing to be found right?
current = root;//set the current to the root to traverse the tree in search of the element
node* parent;//create a parent node for use once the node has been deleted
while(current != NULL){//traverse the tree

I have a quick question about dynamic memory. I know that if you are dynamically allocating memory for a single data array and it fails, you can immediately abort the program via a return statement, but is this also true with multiple data arrays? For instance:
int *foo, *bar
foo = new (nothrow) int [5];
bar = new (nothrow) int [5];
if (foo == nullptr || bar == nullptr)
return -1;
else
/*rest of execution */
If the answer to the previous question is no, do you need to do a delete[] on the arrays that succeeded before terminating the application? Say foo is correctly allocated but bar fails, would you have to do something like this?
int *foo, *bar
foo = new (nothrow) int [5];
bar = new (nothrow) int [5];
if (foo == nullptr || bar == nullptr) {
if (foo == nullptr && bar != nullptr)
delete[] bar;

I have two functions bool check_key(string cKey, string eKey) and bool check_digit(char digit1, char digit2), and I have declared both of them globally (is this the right terminology?) right after the "using namespace std;" and right before the "int main(){".
In the first one, I called the second one . But it is giving me the error: "no match for call to `(std::string) (int&)' ".
Code:
bool check_key(string cKey, string eKey) {
if(cKey!="" && eKey=="") return false;
if(cKey=="" && eKey=="") return true;
if(cKey=="" && eKey!="") return true;
if(cKey.length()!= eKey.length()) return false;
bool flag=true;

the functions checks if the word is a palindrome like"level" "madam" etc. but with input "dfdfdfdffdfd" my recursive function fails.
Code:
/* main.c - Created on: Nov 9, 2013 - Author: Kaj P. Madsen*/
#define MAX 100
#include <string.h>
#include <stdio.h>
int checkPalindrome(char checkString[MAX]);
int checkRecPalindrome(char checkString[MAX], int strLgt, int a);
}
[code]....
results from "dfdfdfdffdfd" added some print to see that its the variables a and strLgt not functioning properly
Code:
dfdfdfdffdfd.
The word is not a palindrome(iterative)
strLgt: 11 a: 0
a: d strLgt: dstrLgt: 10 a: 1
a: f strLgt: fstrLgt: 9 a: 2
a: d strLgt: dstrLgt: 8 a: 3
a: f strLgt: fstrLgt: 7 a: 4
The word is palindrome (recursive)
Why the roundf function is not successfully rounding my numbers.
Code:
#include <stdio.h>
#include <math.h>
//function declarations
void CelToFah (int ctemp, int ftemp);
[Code]....
it produces a correct number when called, but it is not a rounded number, the roundf((float)cel) does nothing. I get the same number with and without it.
The function Reverse does seem to work. Its supposed to take the words in a sentence and then reverse them. For example: "This is nice" to "Nice is this." When I type "This is nice" I get " niceniceis nice"

Below is my .h file and the code below that is my function that I'm having troubles with. Its suppose to take in a users topic and see if that topic exists, if it does exist then find the keyword, commentcompare will find where that keyword is and delete the comment. However its not deleting anything and its returning temp is NULL.
class comment //adds a comment
{

void displayStudent(Student x) {

I have written a delete node function to delete a node in a linked list by the index number. Here is the code:
Code:
void delete_node(struct node **start,int index_no)
{ int counter=0;
struct node *current=*start, *prev=NULL;//Current holds start and prev holds previous node of current
while(current->next!=NULL)
[Code]....
note that I know if the head node turns out to be the indexed position, there is no way to delete that node in the current coding. But please after correcting the present node add that part of the code separately.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
struct node {
int data;
struct node *next;

The above code is a SLL. I have a problem in my deleteNode function. I can't delete the exact data on the list. How to do this right?
I had an assignment that I completed and it was just inserting values into a binary tree and then displaying it. I was wondering what the code would be if I wanted to delete a number in the binary tree, or if I wanted to search for a number. Here is my code for my assignment.

This function should delete each element in the list which is the same as this one typed by user. There are no errors, but function doesn't work. It deletes something, but not this element which should.

The concatenation function working correctly and displays correctly in the function. But if I make another function to display it, it shows this

My program seems to be working fine, except for when I call on my delete function. I don't receive any errors, but when I call the delete function my program outputs nothing and freezes. As in, my print function (which is called before the delete function) doesn't even work. I've tried removing bits of the function to see if I could pinpoint where exactly the issue is, but I've had no luck.
#include <iostream>
#include <string>
using namespace std;
class List{

struct node{
string _data;
