I've made a game and a dialogbox to show up asking to enter a nickname.
The problem is After entering the nickname, it won't show on the highscore list below (textbox)
Where can the problem be? Below is my code:
private void btnPlay_Click(object sender, EventArgs e) {
if (txtName.Text != "") {
Settings.Name = txtName.Text.ToString();

I am making a multiple quiz program. So everything is working fine, except for the part where i'm trying to add a highscore for each user which is being stored in a binary file. I have added a sample of the program containing the error. This isn't the actual program, which is very long.
class user { //The collection of all info pertaining to the users
char user_id[50];
public:
int hscore1;
user() {
strcpy(user_id,"NULL");
hscore=0;
[Code] ....
#include <stdio.h>
float total, avg, max, min;
float judge[4];
int index;
int array[4];
int main() {
total = 0.0;
max = array[0];
min = array[0];
[Code] ....
I dont understand how to make the array when it prints out only print out the final average and the final maximum score with the final minimum score but what its doing at the moment is just giving an average for each individual score taken...
Minimum and maximum scores are displaying 0.0
And it displays these things 4 times in a row i just want it to be displayed once.
I suspect that C++11 would make it possible to declare high rank vectors such as Code: int N = 15; // chosen arbitrary rank vector<vector<vector<...<vector<double>>>>..> vec; // N layers of nested vectors Is there a way to declare such a vector of rank N (given a fixed integer rank N)?
Heuristically I would like to write the declaration like this: Code:
vector<double> A;
vector<A> vec[0];
for(int i=1; i<N; i++)
{
vector<vec[i-1]> vec[i];
} Is there a way to use the new variadic templates to make this work?
I haven't tried to run my program yet, but maybe I will save some trouble if I ask this question first.I am using MC PIC16F690, and I could make a pin high or low by writing RCx = 1 or 0, where x is the pin in the C port. However, I want to use the counter variable from a for() loop as the pin number. Will RC(variablename) = 1 work, or is there another syntax?

I have taken a keen interest in writing trading programs. I have some Python background, a little C# but no C++.
The example below was provided in a book on HFT and I would love to see how the results look. I was hoping that I would just compile it and away you go!
That didn't happen. To start with the author listed this as a function, so I converted it to a main program. Still having issues with my path and where to see the output. Here it is..
Code
void HFT_AvellanedaStoikov() {
FILE* fin, *fout;
double lambda_a, lambda_b, d_lambda_a, d_lambda_b;
int hh = 0, mm = 0, ss, nb = 0, na = 0, prevnb = 0, prevna = 0, prevm = 0;
double bid, ask, prevbid = 0, prevask = 0;
char * p1, *p2, buffer[1024], fname[512];

Write a program that allows a user to enter high scores of a game, keeping tracking of the name of the user and the score. Add the ability to show the highest score for each user, all scores for a particular user, all scores from all users, and the list of users.
This is the program I am trying to write, however I am having difficulty storing the users name and high score, I know I need to store an array for the score but getting confused because of the structure. (By the way I have to use structures as it is a problem from the structures chapter of the ebook I am doing). Below is my code so far. .
Code:
#include <iostream>
#include <string>
using namespace std;
struct highScore
{
string user;
int score;
int highestScore;
int allScores;

View 3 Replies View RelatedOn a project I'm working on, I need to update many QLabels very quickly. Each label needs to be updated at about 20 to 50 hertz and there can be over 50 labels at any given time. The problem I'm having is after running the program for about a minute, the labels freeze and the whole program crashes about 10 seconds later. If I comment out the setText() and setNum() calls and reroute the outputs to the console, it runs fine and never crashes. Why does calling SetText() and setNum() so quickly cause the program to crash and how can I prevent this?
View 5 Replies View RelatedI basically have a listbox that has postcode areas i.e : AE,CW,GU etc etc.
The user selects this and then a postback occurs - an sql statement is builts and a database query operation is performed and the results are returned to a datatable called tempdata.
So far so good. I then need to loop through this datatable and copy the records to my main viewstate datatable which is the datasource for google maps api.
DataTable tempstore = GetData(querystring, "");
//check tempstore has rows otherwise add defaultcust as default otherwise map will be blank
if (tempstore.Rows.Count == 0)
{
[Code].....
So my main datatable can grow and grow as users add more postcodes. However when it gets to around 500 rows or so I get a huge memory spike only on postback and then it settles back down.
My ram usage goes from 2gb to 3gb and if even more postcodes is selected it maxes the memory and crashes my pc.
If I remove the:
dtpc.Importrow(row);
the memory spike goes completely, obviously because the main datatable has no rows. I thought you only run into memory issues when you have thousands of rows?
How to create a symbol table for an assembly language and high level language in c++?
View 1 Replies View RelatedI was investigating for the first time how to generate prime numbers with a considerably high upper limit, around 10^6 or so. I read about sieve's algorithm and tried to implement it using c#, as I had previously brute forced the generation. In Sieve's algorithm, instead of marking the values that were not prime I simply eliminated them, but I don't think that would make any difference. The issue is that my implementation of sieve's algorithm must be wrong, as when I establish the limit as 10^5 I get the following output:
Brute force:
Computation time: 00:00:00.0643539
Sieve's algorithm:
Computation time: 00:00:20:6934223
I have already checked that their generation of primes is correct, but I do not know why one is significantly slower than the other. Here is my code.

how to manually control the temperature of High Power Leds using PID controller. I have two GUIs,one reads the temperature from the Led while the second is used to ON/OFF the Leds and at the same time controls the Led brightness using slider control.The GUI that reads the temperature has a PID controller application on it.The output from this controller is what i want to use to increase or decrease the Led brightness which invariable changes the Led temperature.How to go about using this PID controller to control the Led brightness is what i have not been able to grasp well.The slider on the GUI is scaled from 0% to 100%.My thinking is that the output from the controller should be in percentage which will make me to adjust the slider accordingly.My question is that will this type of arrangment produce an output that will efficiently control the Led brightness. how to accomplish that. Attached to this post is a modified code of a tutorial on PID controller which i found on the net. a tutorial on how to develop a graph. i wish to display the Setpoint,Process value and the output value on a graph.

Currently in development of a cookie clicker clone (for fun)
I am stuck at the idea of the "Cookies Per Second" thing.
Is there a way to implement a per second adder thing that doesnt actually effect the game play (eg even though the player may not be pressing C every second a cookie (or more) will be added, or if they can press C more than once a second, every second a cookie will be added... If you get what I mean).

A buddy and I have been working together to try and create a blackjack game for a project we are doing, and while we have a couple of issues we are trying to get worked out, for some reason we are perplexed as to how we can keep score. Right now, it keeps score but it doesn't reset when it adds a card. So if you had 14 and you hit, and added 3; you would have 31 instead of 17.
// initialize players and hands
srand(static_cast<unsigned int>(time(0)));
GetPlayerInfo(players);
do {
int score = 0;

I have programmed a game where you guess a number (1-6) and if the number is equal to the random number then give the player score + 10. But if I have selected for example 4 players then if the game will give player 1 a score it gives player 2 a score instead? What can be causing this error?
