Below, is the program I completed so far. I need to write a C program that reads in a stream of integer values, each representing an (x,y) pair on the cartesian plane. It then says I need to display the distance and direction from one point to the next. I tested it out, and it works.I need to use a conditional statement, and I'm a little confused how to display the direction(right, left, up, or down).I think I need to use an. "If" statement with my first one being something like:
If (y2 = y1) && (x2 > x1)
and I'm not sure what else to put,or if this is wrong. And with y staying the same and x increasing, the direction would be right.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main(void)
{
int x1, y1,x2,y2,x3, y3,x4,y4,x5,y5,x6,y6; //x and y coordinates
I am having an issue with my sort function. This is one part of the Hash table program. The main issue is that I am trying to sort the pointer table after all of the values have been entered. The ptr_sort function is not a class function and so I am therefore unable to use the class variables psize and pTable. Is there another way I should be trying this? it is a Vector should I use the sort() function from the vector class in STL?
I've finally been able to get my coding corrected after doing this for 5 hours and watching numerous tutorials on it... But I now need to create a table. how to create a table with dashed lines like -----------------, both vertical and horizontal.
Another issue I have is that I'm having trouble trying to get a prompt to ask the user how many programs, tests, and quizzes he/she completed with their total points. I got the basic programming done, but need a prompt asking "How many (quizzes, tests, or programs) have you completed?"
Finally, the do-while loop is driving me insane, where I have to set certain values. If it is greater than 2, then I insert formula 1, but if it is less than 2, then I insert formula 2. Whichever way it goes, the total points earned minus the two lowest scores are then calculated into an average.
Code:
#include <iostream> #include <iomanip> #include <string> using namespace std; int main()
[code]....
The whole basis of the program is to calculate the averages of programs, tests, and quizzes done during a semester at a school. The user is asked how many of each category he/she has completed (total points earned and total points possible). All of this is then calculated into a cumulative class average in a table along with points earned and points possible for each category (along with tests and quizzes combined into one average along with individual averages).
I am having trouble getting values of a dictionary to display in a label and radio button text after the dictionary key is randomly selected.
I first created a class called TheoryQuestions and created a new instance of the class for each dictionary entry. Each entry contains strings for Question, RadioButton Text(x4), and Correct Answer.
The random generator is actually selecting a random number as I can display the generated number in a label. The problem is that the dictionary string values held in the dictionary position represented by the random number are not being displayed.
Here is my TheoryQuestion Class
public class TheoryQuestion { bool BeenAsked = false; public string Question { get; set; }
[Code] .....
Its probably some mistake I have made but I just can't see it.
get my code to display a table with values from a file. my current code fills up all the sections of the table with the same data. here is what I need: from a file .txt I upload numbers that should show a table like this :
Lake Beach Average E-Coli Level Recommendation Ontario Kew Beach 47.12 OPEN Huron Goderich 51.13 CLOSED Simcoe Sibbald Point 0 INSUFFICIENT
my problem is in the last two columns. The ave. E-coli has one value for all which should look like the above table but my code doesn't. Also my recommendation shows the beach # instead of open close or insufficient.the data is:
I am trying to work with C# and i am stuck here. My problem is i want to retrieve the count of all the users in a specific side. Let me Explain. Here is my table snapshot with sample data.
Now what i want exactly is that i get the count of users in a specific side as i give a user id as a parameter.The data is stored in MS Sql Database and i have to implement this on a website so efficiency of code is also a issue.
Suppose i give 1001 as input The output should be : Left:1 , Right: 8
if 1002 is input The output should be : Left:5, Right:0
if 1003 is input The output should be : Left:3, Right:0
if 1004 is input The output should be : Left:0, Right:0
if 1005 is input The output should be : Left:1, Right:1
and so on. how to implement this thing. I also want to get a code which would return an array of all child users of a particular ID in a hierarchical manner so that i could process that data with RadOrgChart Control.
I have to develop a C program that reads a very complex txt file (output of a calculation code, so full of mixed text and numerical tables), search for a specific table in it and individuate/print or replace a specific value with assigned position in the table.
i new to c++ programming. i have a program due soon in vector addition. i am to design should be able to add vectors with certain magnitude and direction and give its resultant magnitude and direction (i know how to do this mathematically but programming is not working. the user should be able to select how many vector he/she wants (i don't know how to do this, so i added 3 vectors). here's my work - i did this purely algebraically. it's still incomplete but it compiles. my "if else" statement also doesn't respond correctly.
#include <iostream> #include <string> #include <vector> #define PI 3.14159 #include <math.h> std::vector<int> v; // declares a vector of integers using namespace std;
implementing an algebra function.(a+b)(a-b).does c++ support this sort of function.Did a quick search on google and all of them suggested using libraries like boost. is there anyway to do this without a library?
It is technically not a programming question and is more maths oriented. It has to do with game AI and specifically getting the AI to rotate correctly. I am trying to create the base method that handles AI rotation. It will take a target orientation and rotate the entity from it's current orientation to that target orientation.
Let's say we have a Entity that has the orientation of 1.57079 Radians (90 Degrees) and we want to change that Entity's orientation to 0 Radians (0 Degrees). How would one find the correct way to rotate from just them two orientations (IE find the shortest rotation direction from a current orientation to a target orientation)?
As my implementation stands now the Entity rotates just fine I think but always in a clockwise rotation (Because I can't figure out how to determine the best rotation direction). For example using the previous number (1.57079 Radians to 0 Radians) the Entity will rotate all the way around 270 Degrees clockwise instead of rotating just 90 degrees counter-clockwise.
I have thought about possibly projecting vectors a short distance forward from the current orientation and target orientation to figure out the rotation direction but not sure if that is a good way to implement it.
Is there any way to allow user to resize a CDialog only in one direction ? I mean, by width, but not by height ? How ? I noticed that overriding WM_SIZE, I can do nothing about this issue ...
So I need to make a program that prints a triangle of symbols in a certain direction.
For example: Code: How many rows? 3
@ @@@ @@@@@
How to do that. It's rare that I post without figuring anything out, but I'm just simply not sure. I have a program that prints a triangle in a similar direction, so maybe if I could get some hints as to what to do with that (HINTS, not direct source code) .
Code: #include <iostream> #include <iomanip> using namespace std; int main ( ) {
Nothing complicated, and it works well ... except one thing: when I press the shift key and the mouse is moving by SetCursorPos, is moving pretty slow ... why ? I can not figure out why ! For testing, I attached the test project ...
If a user enters a string of boolean algebra it will ouput the table.
I have input parsing, cycling through the combinations, and outputing working. However once i parse the input I am not sure what to do with it. I have thought of having it write the parsed input to a new file as a function and then use that function, but that seems bad.
How to dynamically create the function, how to implement it.
BTW This is a console function, if that changes anything.
1) Count the number of rows in the table booking that are open and where the booking.postcode is "MK",
2) Take a note of the plot (in booking.plot_id), and then update the table plot.jobs with the value count.
For example running the SQL query when booking table has the following rows:
Would see the following highlighted values in plot.jobs being updated to 1:
I managed to resolve it with this code so far (note I am using Connector/Net):
public void RefreshPlot(){ string query = "SELECT Count(*) AS count, plot_id FROM booking WHERE postcode='MK' AND status='open' GROUP BY plot_id"; var cmd = new MySqlCommand(query, _connection); var da = new MySqlDataAdapter(cmd); var dtCounts = new DataTable(); da.Fill(dtCounts);
[code]....
Currently, my code only checks for existing rows in the booking table and updates the plot table. However if the row gets deleted in the booking, then the changes are not reflected in the plot table.
Example: If we delete the row with plot.id=1 and plot.plot_id=4, then booking.plot_id should go back to being 0, if it was initially 1. At the moment, it doesn't. How would I update my SQL statement to better reflect this? In a sense, it should check for "non-existent" rows, i.e. the impact that the row plot.plot_id=4 & plot.id=1 has on booking.plot_id when deleted?
I have a C# .NET Application which get data from QuickBooks via the ODBC Driver and save the result to C# data table. So, I want to transfer this data table to a mysql table on my own server. That's the code I use:
using System.IO; using MySql.Data.MySqlClient; //Add mysql dll on the .NET Tab in Project's references string connStr = "DSN=QBTest;"; string myServerAddress = "192.168.0.243"; string myDataBase = "CostTest";
write a c++ program that reads an unknown number of integer values and then print count, sum and average of odd values, even values, positive values, negative values!!
I've been working on a homework assignment that randomly generates integers and populates them into an array (array1). The program is then supposed to:
1.) copy those values to a second empty array (array2)
2.) sort the values already in array1 (using an inline function)
3.) enqueue the unsorted integers from array2 into a heap vector
4.) a third empty array (array3) is supposed to be populated with those unsorted integers (by dequeuing them from the heap), sorted in reverse order.
But no matter what I do, I always get garbage values like these:
I've tried using both a standard random number generator:
array1[i] = rand()%100+1;
And the d_random.h file my instructor gave us, but nothing works.
Here's the code from all 3 files:
HeapTester.cpp
Code: #include <iostream> // Provides cin, cout #include <cstdlib> // Provides EXIT_SUCCESS, rand, srand #include "d_random.h"//Provides random number generator #include "Heap.h" using namespace std; // Use C++ Standard namespace //Elements in each array. const int arrayLength = 15;//100;
I was wondering if this was even possible and if so, how do I do it.
else if (speech.ToLower().Contains("truck") && speech.EndsWith(number)) { Here I would like to see if my speech had ended with any of the values i would have stored in the string "numbers". If it did, I would like to just take the value and add it to a new string called whatever }
I have tried this a million different ways and I cant get it to work. I'm not even sure how I would go about storing tons of different numbers in one string, or if that's even possible.
I'm trying to display the contents of this map. I'm having some trouble where the program ceasing to display after "Index Contents."(lines 33 -40) If I move the display for loop right where I'm inserting the values (line 52) into the map I get output. I'm not sure where bug is.
