In C++, how do I do this?

Apr 2, 2013Write a program that prompts the user for the x and y coordinates of a point on the x-y plane, and then displays the position of that point in polar coordinates.
The program must execute via a function ‘polar’ that is called from the main function. This function accepts x & y coordinates as input value parameters, and then returns, through reference parameters, the polar coordinate position of the point (r and theta).
Could in theory be written entirely in the main function; however, to meet the problem statement the code must include a user defined function that returns polar coordinates to the main function via reference parameters.
Some programming hints:
(i)Reference parameters are declared using an ampersand after the declaration type: for example – ‘int& number’ declares a reference parameter ‘number’ of type ‘integer’.
(ii)You’ll need the cmath library for arctan and sqrt functions. The C++ syntax for the arctan function is “atan(x)”.
(iii)The C++ arctan function returns an angle in radians. For output to the screen convert the angle theta from radians to degrees.
(iv)Program should work for x, y values in all four quadrants of the x-y plane.

View 1 Replies View RelatedVisual C++ :: Reading Character Symbols On Lines Of Text Position By Position?
Mar 4, 2013What I have to do is write a small program in C++ to parse the symbols that are used on 5 different lines of text in each position until position 30 is reached on each line. The goal of the parsing program is to interpret the symbols (characters), if there are any per each position, on the 5 lines of text in order to output the actual data that the group of symbols represents.
My question for is this: Is there anything special from a C++ environment that should go in to something like this outside of using standard stuff like the math associated with the search algorithm that has to happen here? The symbols are located in a file, so I know I have to include "iostream" and a few other headers. But outside of header inclusions and the code necessary to iterate and streamline the search and interpretation process, am I missing anything special that I couldn't otherwise find through simple google searches?
Visual C++ :: Enable / Disable Menu Item 2 In OnUpdate Handler Of Menu Item 1?
Sep 15, 2014I have two menu items. When item 1 is disabled, I want item 2 to be disabled as well. In the OnUpdate handler of menu item 1, I have tried to use "t_pMenu = pCmdUI->m_pMenu;", "t_pMenu = pCmdUI->m_pSubMenu;" and "t_pMenu = pCmdUI->m_pParentMenu;" but I always get NULL t_pMenu. How can I achieve this purpose?

How can I add this output in my program.

int array[15]={28,3,16,4,3,16,5,8,4,12,5,4,8,21,40};
int x=0;
int done=0;
int item;

array locations : 3 8 11
C# :: Get Item From List In Another Class
Jan 15, 2014How can I get the items from a list into textboxes. I am doing an windows form application in visual studio.
I have the first form with a couple of textboxes.
I want the inputs be saved in a list. And then displayed in another form. How to move on. The class with the list looks like this:
public class Casecs {
public List<caseInformation> fallInformation = new List<caseInformation>();
public class caseInformation {
public string caseId { get; set; }
public string phoneNumber { get; set; }
public string description { get; set; }
}
Then the form with the inputs in textboxes looks like this:
Casecs Casecs = new Casecs();
Casecs.fallInformation.Add(new ERIS.Casecs.caseInformation {
caseId = txtCaseId.Text,
phoneNumber = txtPhonenumber.Text,
message = txtMessage.Text
});
Then where I am stuck a form with some textboxes where I want the list items to be displayed:
public partial class btnDispatch : Form {
public btnDispatch() { }
public btnDispatch(List<Casecs.caseInformation> fallInformation) {
InitializeComponent();

C# :: Run SQL Query For Each Item In Listbox?
Aug 2, 2014I have a C# WPF program that takes a SQL query and populates a column from an Oracle database into a listbox on the form. I would like to be able to compare all items populated in the listbox, and run a SQL query for each item, populating those values into a different listbox.
So far, I have this code:
string sql2 = "select unique apps.fnd_application_all_view.application_name, fnd_responsibility_vl.responsibility_name, fnd_form_functions_tl.user_function_name, fnd_form_functions.function_name, fnd_form_functions_tl.description, fnd_form_functions.type FROM fnd_compiled_menu_functions, fnd_form_functions, fnd_form_functions_tl, fnd_responsibility, fnd responsibility_vl, apps.fnd_application_all_view WHERE
[code]....
I would like to be able to basically take the "Responsibility_Name" value from the first listbox (lstResponsibilities), which is already populated, and use those values to in the "sql2" query to find the "Function_Name" and populate "Function_Name" in the second listbox (lstFunctions).

C++ :: How To Insert Item Into Binary Tree
Jun 30, 2013I am trying to write a function that inserts an item into this binary tree in C++.
template <typename T>
struct BTree {
T val;
BTree<T>* left;
BTree<T>* right;
BTree(T v, BTree<T>* l=nullptr, BTree<T>* r=nullptr) :
val(v), left(l), right(r) {}
};
Here's my attempt.
template <typename T>
void insert(BTree<T>* tree, T item) {
if (tree == nullptr) {
tree = new BTree<T>(item);
} else if (item < tree->val) {
insert(tree->left, item);
} else {
insert(tree->right, item);
} }
I think this function may not be working because I am modifying `tree`, which is a local variable. How do I actually modify the current pointer that `tree` represents, not just `nullptr`?
C++ :: Enable / Disable Menu Item
Nov 19, 2013I have ploughed through the exchanges in all the forums, yet I still cannot make it work. The following is a tiny Code::Blocks program, written to isolate the problem:

#define ID_FILE 102
#define ID_DISABLE103
#define ID_ENABLE 104
#define ID_MESSAGE105
#define ID_EXIT106

case ID_ENABLE is similar to case ID_DISABLE above, and neither works. case ID_MESSAGE and case ID_EXIT both works as expected.I have tinkered with EnableMenuItem(), but without success.
