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){
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.
How can I declare global 'delete' operation multiple times? Like, I've an implementation of global 'delete' operation in a file 'x' but I want a different behavior in file 'y'. However, if I override it again in file 'y' I get multiple definition error.
The first line indicates how many paths exist in my design. The second and third lines are those lines(the first number indicates 2 pairs, so 10,1 and 2,7 are 2 pairs) The first element in the third line indicates 3 pairs and the pairs are 8,3 and 7,7 and 10,7.
I have been able to read the text file and store these into ONE array. However, I need to divide them up and have each line in a seperate array.
So for example
array alpha to contain 10,1 and 2,7 array beta to contain 8,3 and 7,7, and 10,7
I currently have globally declared arrays, which are accessed by multiple functions. I want to turn the program so that the arrays are no longer globally declared, but are passed to functions by reference.
I have one problem with passing the arrays: I found that, through debugging, I HAVE TO resize the array when I pass it by reference. For instance, I was using int a[10] when it was globally declared, when it is passed by reference with size 10, it does not work, instead it should be higher than 10 (certain number). Why is this happening? I do not get it...
I'm trying to create a function where it allows the user to type in multiple amounts of integers, so if the user wanted to have 3 different storages that hold different integers, the input would look something like this:
5 97 12 31 2 1 //let's say this is held in variable "a" 1 3 284 3 8 // "b" 2 3 482 3 4 // "c" 2 3 4 2 3 // "d" 99 0 2 3 42 // "e"
Since we don't know what number the user will input every time, I'm not sure how to create a dynamically allocated array that will create an x amount of arrays every time.. I want to be able to access each index of a, b, c, d, e or however many arrays there are.
So far, this is what I have, but I'm having trouble creating the arrays since it's unpredictable. I'm purposely not using vectors because I don't really get how pointers work so I'm trying to play around with it.
int* x; int length, numbers; cin >> length; x = new int[length] for (int i=0;i<length;i++) { cin >> numbers; //this doesn't work because it only grabs the first line for some reason x[i] = numbers }
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
