I have been asked to explicitly convert a decimal number to hexadecimal (radix sixteen) number in 1s complement...how the heck is that done?

I can convert to a binary number using 1s compliment...do I just take that and convert to hex after the fact?

Re: linked list errors

So you need to create a linked list with three nodes and then call a function that follows the links and counts the number of nodes...is that correct?

Silly Sentence Generator with Hash Map

Last quarter our last assignment was to create two programs that gernerate silly sentences from words contained in a file.

I was able to create the program with a map, but have no idea how to do it with a hash map. Since it was the end of the quarter, the instructor didn't go over how to do this.

I am using Microsoft Visual Studio 2005 (the school uses Linux, of course...so even the example code is useless to me here).

I am attaching the project files and am wondering if someone would be kind enough to explain how to do this with a hash map.

This attachment is potentially unsafe to open. It may be an executable that is capable of making changes to your file system, or it may require specific software to open. Use caution and only open this attachment if you are comfortable working with zip files.

Re: Merge Sort

Yeah...like that.

I actually saw that in my research, but didn't think I could convert it to what I needed.

Your suggestion prompted me to look at the code a little closer, and I came up with this solution:

template <class T>
void mergeSort(vector<T>& s) { 
	vector<T>* temp = new vector<T>(s.size());
	if(temp != NULL) { mergeHelper(s.begin(), 0, s.size(), temp->begin()); }
	delete temp;
}


template <class T>
T max(int x, int y) {
	if(x > y) { return x; }
    else { return y; }
}


template <class Itr>
void mergeHelper(Itr start, unsigned int low, unsigned int high, Itr temp) {
	if (low + 1 == high) return;
	else {
		unsigned int center = ((high + low) / 2);
		int l = low;
		int h = center;

		mergeHelper(start, low, center, temp);
		mergeHelper(start, center, high, temp);
		
		for(int i = 0; i < (high - low); i++) {
			if (l < center && (h == high || max(start[l], start[h]) == start[h])) {
				temp[i] = start[l];
				l++;
			}
			else {
				temp[i] = start[h];
				h++;
			}
		}

		for(i = low; i < high; i++) { start[i] = temp[i - low]; }
	}
}

Thanks for the nudge in the right direction!

Re: image align

Have you tried specifying a height and width for each image?

Merge Sort

I am trying to learn how to write a merge sort function, but I have only gotten so far with the book I am using now:

template <class T>
void mergeSort(vector<T>& s) { mergeHelper(s.begin(), 0, s.size()); }


template <class Itr>
void mergeHelper(Itr start, unsigned int low, unsigned int high) {

	// If current element is the only element in the vector, return the element
	if (low + 1 == high) return;

	// Find the center of the current vector
	unsigned int center = ((high + low) / 2);
	
	// Sort lower half  
	mergeHelper(start, low, center);

	// Sort upper half
	mergeHelper(start, center, high);

	// Combine consecutive sorted ranges [first, middle) and [middle, last) 
	// into a single sorted range [first, last)  
	inplace_merge(start + low, start + center, start + high);
}

I understand "what" the inplace merge function is supposed to do...but I'll be damned if I can figure out how to write the code for it and I have been unsuccessful in my online searches.

How would I write the code for my own inplace_merge function?

Re: Why do people wish for tableless with CSS?

That depends on what you consider "wrong."

Technically, yes, according to the W3C, tables for layout is "wrong." I think browsers still have a little way to go in the way of rendering CSS uniformly across platforms, so sometimes a table is easier for those who are familiar with them.

I personally use CSS...but I won't hang someone who doesn't (unless they are working on my site).

Hey...I've been known to use a screwdriver for a chisel in the past. It may not be "right"...but it works in a pinch.

Re: Why do people wish for tableless with CSS?

Ha!

It really is a preference issue.

Most people will tell you that tables were created exclusively to hold tabular data...and that any other use is wrong.

Since we have been using tables long before CSS, this is obviously false.

If your client doesn't care and you are GOOD at using tables, knock yourself out. If you are using 50 tables to position items on a small page, however, you should really look into learning CSS.

Re: DreamWeaver 8: FTP information does not save for sites

Click on sites/manage sites/edit and click through until you get to the ftp page for the site you want.

Click the SAVE checkbox next to "What is your FTP password?"

I've never had a problem with it not connecting to my site. If it is not connecting, recheck your ftp hostname, username, and password. You should also check to see if you are connecting to the correct folder on the ftp server.

MyString Woes

I was absent for the discussion and lab due to illness and I am at a total loss as to how to do this assignment.

Implement the my_string class in header file my_string.h, so that the test code given below reports SUCCESS.

// test_my_string.cpp

#include <iostream>
#include <string>
#include <cassert>
#include "my_string.h"

using namespace std;

//#define STRING string
#define STRING my_string

int main()
{
   STRING s1; // s1 == ""
   assert(s1.length() == 0);

   STRING s2("hi");  // s2 == "hi"
   assert(s2.length() == 2);

   STRING s3(s2);  // s3 == "hi"
   assert(s3.length() == 2);
   assert(s3[0] == 'h');
   assert(s3[1] == 'i');

   s1 = s2;  // s1 == "hi"

   s3 = "bye";  // s3 == "bye"
   assert(s3.length() == 3);
   assert(s3[0] == 'b');
   assert(s3[1] == 'y');
   assert(s3[2] == 'e');
   
   s1 += "re";  // s1 == "hire"
   assert(s1.length() == 4);
   assert(s1[0] == 'h');
   assert(s1[1] == 'i');
   assert(s1[2] == 'r');
   assert(s1[3] == 'e');

   cout << "SUCCESS" << endl;

I cannot get the program to get past assert(s3[0] == 'h'); nor can I get cout << s3[0]; to work.

What am I missing here?

Re: is dreamweaver is better tahn hand code?

I have to agree.

Dreamweaver derived code is absolutely horrible. I use dreamweaver, but only as a coding tool...not to do the coding for me.

You should know how to code by hand before using any program to do it for you...just like you should know how to add before using a calculator.

Re: Output problems

I had a midterm problem similar to this last year.

The question was

3) Write a function using the following structure and prototype.
struct stat
{
    float avg;
    float median;
    float *mode;
    int nModes;
};

stat *avgMedMode(int *,int);
The function takes in an integer array and the size of the array.
Then returns a pointer to a structure containing the average, median
and mode. I will input a small array to test this out so ask for
how many inputs to fill the array, then the values to place into the
array. Make sure you delete the dynamic array creation for the mode
when you exit the problem.

My solution (as a module of the entire midterm program) is as follows:

// Frank C. Jamison
// April 08, 2006
// CIS 17A - Section 43052
// Borland C++ Builder Enterprise Suite Version 6.0
// Purpose:  Midterm Examination Program 3
// Midterm Examination

#include <iostream>
using namespace std;

// Structure Declarations - Midterm Program 3
struct stats {
  float avg;
  float median;
  int  *mode;
  int   nmodes;
};

// Function Declarations - Midterm Program 3
stats *avgMedMode(int *, int);
int   *createArray(int);
void   displayStats(stats);
int    findHighFrequency(int*, int);
int    findNumModes(int *, int, int);
float  getArrayAverage(int *, int);
void   getArrayElements(int *, int);
float  getArrayMedian(int *, int);
int    getModeArray(int *, int, int *, int);
void   programHeader3();
void   sortArrayElements(int *, int);

// Function Declarations - Multiple Files
void clear();
bool validLoNum(int, int);
void wait();


//*****************************************************************************

Re: change the font/color of the selected text on a web page through javascript

Here is a script that captures any text that has been highlighted with the cursor. In Internet Explorer, it even grabs text highlighted within a text box or textarea.

It shouldn't be to much of a stretch to modify the code to change font size and color instead of copying it to a textbox.

Re: Javascript Help

The problem is that your array

Names[0] "Matt"

Is actually a two dimensional array of characters...so

Names[0][0] = 'M'
Names[0][1] = 'A'

etc.

You will need to use something like this...

tmenu[3] = [["Departments", "#", "dropdown"]];
		smenu[3] = new Array(); fmenu[3] = new Array();
		smenu[3][1] = [["Administration", "#", "noFlyout"]];
		smenu[3][2] = [["Human Resources", "#", "flyout"]];
			fmenu[3][2] = new Array();
			fmenu[3][2][1] = [["Home Page", "#"]];
			fmenu[3][2][2] = [["Employment Opportunities", "#"]];
			fmenu[3][2][3] = [["Teach in Iowa", "#"]];
			fmenu[3][2][4] = [["Info for Teacher Candidates", "#"]];
			fmenu[3][2][5] = [["Master Contract", "#"]];
			fmenu[3][2][6] = [["Iowa Teaching Standards", "#"]];
			fmenu[3][2][7] = [["Non-Discrimination Policy", "#"]];
		smenu[3][3] = [["School Improvement", "#", "noFlyout"]];
		smenu[3][4] = [["Financial Information", "#", "noFlyout"]];
		smenu[3][5] = [["Facilities", "#", "noFlyout"]];
		smenu[3][6] = [["Food Service", "#", "flyout"]];
			fmenu[3][6] = new Array();
			fmenu[3][6][1] = [["Home Page", "#"]];
			fmenu[3][6][2] = [["Account Balances", "#"]];
		smenu[3][7] = [["Child Care", "#", "noFlyout"]];
		smenu[3][8] = [["Transportation", "#", "noFlyout"]];

Re: Drop Down Menu - Problem Opening in IE

Without loading this into a Web page, there are a couple of things it could be,

If there is a 1px space between the submenus, the menu will close when you roll over it.

The other common problem is te css for hovering.

As for menu overflow...there is really no foolproof way to do this. I would suggest having the browser check the width of the window vs. the position and width of the menu and reposition the submenus on overflow.

Your best bet is to design your site in such a way that this situation does not happen or happens only under certain conditions that can be easily avoided.
