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;
#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?
The bottom three functions do not work. Nor are the finished to the extent. I do not know how the data members are being accessed and is only giving me the last output. The overall goal of this program is to output the highest grade with student name and age, lowest grade with student name and age, and the average of all grades. The file is given and is commented out for you to see what the file looks like.
// Header Files #include <iostream> #include <fstream> using namespace std; // Global Constants const int STD_STR_LEN = 10;
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..
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;
One of my programs I recently created, needs higher precision then what doubles can provide. So I am wondering how I install a library like this [URL] .... I don't quite understand exactly how to install them. Im using visual studio 2012 ultimate right now!
On 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?
I 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?
I 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:
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.
I want to do something like when you have completed the first question then the program will give you +3 in coins then you have completed next question then I want the program to add 3 more so it says you have a value of coins 6. But I do not know exactly how to do this the code I begun to write was this:
Code: #include <iostream> using namespace std; int main()
[Code] ...
This code works for 1 question but I want it to work like add 3 for every question the user guesses correct. Like if user enters the correct answer 3 times then he/she has a value of coins 9.
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; bool busted = (score > 21); ShuffledDeck(deck);
I have to develop an application named smart client score board in c#
Main requirements for this application are that application should display the live scores, detailed score board, running commentary (in text), players and team profiles, statistics of matches, results and fixtures for cricket.
sort out websites which support rss feeds for full score card.
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?
Code: #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int cube; int number[4];
I am using the following code to print in SDL screen
SDL_GL_RenderText( timer, font, color, &position); sprintf(timer," Time : %d",time);
to print in SDL screen(used with opengl) , i am doing project on C++, as "sprintf" is C style function , so i can't do like this , i am trying to use" ostringstream" , but i am not sure how to use it.
I'm writing a program to keep score of a game of bowling. Whenever I run the program, it comes up with the correct starting point, but whenever i type in the first number and click enter, the program stops running and it gives a return value of something similar to 3221225477. Here is my code. I think the problem might be that I'm not using pointers..? but I could be way off..I'm new to programming.
#include <stdio.h> int main() { int frame[10][3] = {{0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0}, {0,0,0}}; int frameOutcome[10], frameTotal[10], currentFrame = 0, totalScore = 0;
I am trying to correlate the student's highest score with that student's ID. The old code is in blue and the new code is in green which includes a sort. The particular information in question is in red.
Ide1
Code: #include <stdio.h> int main(void) { /*Set up two arrays to include up to 50 elements each.*/ int st_numval_id[50] = {0}, st_val_tstscr[50]= {0}, i = 0, j = 0, temp;
[Code] .....
Enter the student's id and test score:
/*After the following input, then enter 0 to end the input*/
Student ID Test Score Letter Grade ------------ ----------- -------------- 1653 77 C 1945 72 C 1020 50 F 1955 92 A 1900 81 B
ABOVE AVERAGE STUDENTS
Ave Test Score Students Above Ave Number of: A's B's C's D's F's ----------- ---------- --------- --- --- --- --- --- 62.00 4 1 1 2 0 1
THE STUDENT WITH THE HIGHEST TEST SCORE
Student ID Test Score Letter Grade --------- ---------- ------------ 1900 0 F
