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.
I have to create a program that holds three arrays one for the persons last name one for the points scored and one for the player number, now i've got all the arrays and things done but i'm confused as to how i'm going to delete an entry so far the options i've got working are create player, list player, update player, retrieve player and exit.
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace PlayerSystem6 { class Program { static void Main(string[] args){
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.
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// }
I'm having trouble understanding how to get my phonebook to print out it's entries. If I just have one entry, it will correctly display it but if I have 2 or more, it leaves out chunks of that entry's data.
I'm creating a program that holds three arrays one for the persons last name, one for the points scored and one for the player number, now I've got all the arrays and everything done but I'm not sure as to how I'm going to delete an entry for multiple arrays.
This program is an address book where you caan add/view entries. I'm having a problem printing out entries. Why the information isn't getting saved into the structure array?
Code: #include <iostream> #include <string> using namespace std; struct contactinfo
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; }
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.
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.
I am developing a program that needs auto start at windows startup. For that I need to add Registry entries. Also the program needs to read some registry keys. What are the functions i need to do these.. Simply I need to
check if the startup key already exists add a new key if it doesn't exist read a key values
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) {
[Code]....
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 ?
I'm writing a version of the classic Snake game. However, my board is not printing correctly. The right hand border is in the incorrect location. Also, when I randomly generate where the food ('X') is located, it only generates on the edges of the boundaries.
#include <iostream> #include <cstdlib> using namespace std; const int ROWS = 21; constint COLS = 61;
Well I have my program running and the Variables are not passing correctly and the return statements are not returning correctly. Here is the parts that are not working.
