C/C++ :: Won't Delete Entries Correctly

Mar 5, 2015

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

[Code]....

It compiles just fine and it will add new entries and print the entries just fine but when I go to delete an entry it will delete it but it will mess up the one before it.

C :: List - Why Delete Function Doesn't Delete

Dec 9, 2014

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;

C :: Summing Entries In A For Loop

Sep 26, 2014

Basically, say i wanted to sum all the values enter for x. First, i ask the user how many x's there are, then create a "for" loop to ask for x1, x2, x3, .. xn. Then i want to know the cumulative total of x. How would i do this? This is the sample code i have made right now inside of my main function:

Code:
int N;
int I;
int X;
//This is where i ask for how many x's there are//
}

C :: Setting Hash-table Entries To NULL?

Apr 21, 2013

Here is my code so far:

Code:
//LINEAR CHAINING OR SEPERATE CHAINING...
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

#define MAX_USERNAME_LEN 15
#define MAX_PASSWORD_LEN 20

[Code] ....

When I compile I get this error:

Code:
simpleauth.c: In function ‘initialize_table’:
simpleauth.c:179:30: error: incompatible types when assigning to type ‘DBEntry’ from type ‘void *’

I am sure its a simple error but I cannot seem to figure out how to set all the entries in the database to NULL. My plan is this:

1. Set all entries to NULL.
2. Check if entry is empty, if empty insert into hash-location, if not increment until empty...

Part 2 seems easy to me, but I cannot set them to empty....

C++ :: Heap Sort Algorithm Crashing After 4100 Entries?

Nov 18, 2013

I developed the following heap sort algorithm code, and for some reason anytime it goes above 4100 entries, the algorithm completely crashes. It works perfectly up until that point but I can't see why it would crash?

void heap_from_root(MVector &v, int i, int n) {
int end=n,j=0;
// Identify the lowest root and how many sons it has. If it only has one son, set j=1.
if (n==1) { n = 0; j = 1; }
else if ((n-2) % 2 == 0) { n = (n-2)/2; }
else if ((n-1) % 2 == 0) { n = (n-1)/2; j=1; }

C++ :: Program Inputs The Number Of Rows And Columns And Asks For The Entries

Feb 7, 2015

I am writing a program that deals with 2d arrays. The program inputs the number of rows and columns and asks for the entries. When the program run and compiles it works perfectly until it outputs then it gives me a warning.

Here is my code:

#include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
int row1=0,col1=0,i,j;
//int a[row1][col1];
int** a= new int*[row1];

[Code]...

I am learning how to do this before I can move on so it can read a text file of numbers.

Also I am having problems with ////delete [] a[];///// I took it out because it made my code compile and run but when I add it in, it gives me an error:

matrixtesting.cpp|56|error: expected primary-expression before ']' token|

I know this expression is suppose to deallocate the array.

C Sharp :: Call That Counts Number Of Entries In Database - Cast Error

Jul 14, 2013

I have an issue with a database call. I've got a database call that counts the number of entries in the database:

        private static Int32 dbCount() {
            SqlCommand cmd = new SqlCommand("SELECT COUNT (*) FROM Employees", conn);
            conn.Open();
            Int32 count = (Int32)cmd.ExecuteScalar();
            conn.Close();
            return count;
        }  

Afterwards I'm using this as a check throughout my application:

           if (dbCount > 0)  {
                // do something
            }  

When I execute this code I'm getting the following error: "Operator '>' cannot be applied to operands of type 'method group' and 'int'"

So I'm guessing it has something to do with the cast of the dbCount-object but I don't understand why as I already stated that the count-object to be an Int32.

Visual C++ :: Creating Loop To Call In Entries From Text File Named Set

Jul 14, 2013

I am trying to create a loop to call in the entries from the text file named Set. The entries of Set.txtare :

1 2 3
2 4 5
and so on .. (64 such combinations)[/CODE]

It basically means the first combination for testing is 1 2 3 and next has to be 2 4 5 and so i have 64 such entries defined in set

My test files are located in D://data// and are named tst_data1 to tst_data64.

I created a loop for test set but its incorrect

Code:
// loop for test samples
char basefilename[] = "D://data//";
char , testFilen[160], numiChar[10];

for (int i=1; i<=64; i++) {
strcpy(basefilenme, "D://data//");
strcat(testfilename, Set[]);

[Code] .....

How can i call the Set .txt and how to define it.

C :: How To Typecast Correctly

Feb 17, 2015

so i have this problem with my code ( not running)i want to read ( 2 double numbers x,y) and ( one integer z) then calculate reminder of x and y ( after they both converted to integer) and the formula : x^2 + y^2 + z^2and : x^z + y^z

here is what i came up with :

Code:
// compute.c

#include<stdio.h>
#include<math.h>
int main(void)
{

it also says in q : be sure to test the user input to make sure x,y,z are positive . any negative or zero should not be accepted and must print error msg ==> do i have to have an if statement here ? or the while loop is enough ?
