C :: Selecting The Highest Occurrence Char
Dec 14, 2014
it's not my primary language, so my code variables are in my language.
Code:
FILE *eng;
eng = fopen("eng.txt", "r");
if(eng == NULL){
[Code]....
fclose(eng); It's a piece of my code. Some explanation: From file, where is full of words under selves. I cut it on word and from word i'm printing:
1) word
2) how many letters in the word
3) word backwards and
4) viz. problem is down
For first: There i have warning: while(feof(eng) == NULL); like (comparison between pointer and integer) i don't get it. For second i have a big problem. I must from every word print the most recurring character.
For example: nondeterministically -> the most are N and I. And if, there is more then one most reccuring char, you choose one of them.

I'm doing a project where I have to store information gathered (temperature and the time it was taken in seconds) in two separate vectors. After an unknown amount of data has been entered, and the end-of-file has been reached, I have to display the highest temperature and the time(s) it occured (bear in mind that the highest temperature may be recorded more than once). The output of that part should be as follows:
Highest temperature: 51
Recorded at time(s):
22:45
2:27
Something like that. The time should also be converted to hours and minutes. To the point: I've done some research on bubble sorting, but they only use it for arrays.

I have
#define LessSymbol -1
#define MoreSymbol 1
#define NeitherSymbol 0
#define MAX_COLS 20
#define MAX_ROWS 20
#define MAX_CHAR 3
char averageMap[MAX_ROWS][MAX_COLS];
char rowCount[MAX_ROWS][MAX_CHAR];
char colCount[MAX_COLS][MAX_CHAR];
I have other stuff in the code, but basicly, at this stage i have a map of 1's,-1's and 0's in a 20 x 20 map. I just want to count the occurrences of each and basicly tally them in the 3 colums/rows at the end of the bloc. so far ive tried many different if statements, here is what i tried last.
for(row = 0; row < MAX_ROWS; row++){
rowCount[row][0]=0;
rowCount[row][1]=0;
rowCount[row][2]=0;
} for(col = 0; col < MAX_COLS; col++){
[Code] ....
Its outputting 20 as a result for each row. Its like its counting the symbol no matter what it is.

I have N vectors which look like this:
[1→m] [m+1→2m] [2m+1→3m] [3m+1→4m] [4m+1→5m]..... [{(N-1)m}+1→Nm]
I want to select 1 element from each vector without duplication of any combinations.
Essentially only when all combinations are done with 1st element in first vector ,only then it should move to next element in first vector say i have elements :[123] [456] [789]
my combinations should be like
147
148
149
157
158
159
167
168
169
247….
Also, i need no repetitions and only after all combinations of 1 are done only then the loop has to move to next combination ie 247 combination and so on.
i tried NCK (n choose k) command but it gave me random combinations.how should i go about it with using minimal for loops

I have to write a program that selects a random color from an array. I used the srand (time(0)); statement but it still gives me the same color each time. Here is my code.
// Color.cpp
#include <ctime>
#include <iostream>
using namespace std;
#include <string>
#include <cstdlib>
#include "Color.h"

Supposing you have a 3 or more overlapping arrays (arrays having elements in common), and you wish to select 2 or more of the arrays with the maximum number of elements but less overlap as compared to the rest of the overlapping arrays.
Eg. A[4],B[6],C[5]. A+B contains 10 elements but say the overlapping element is 3, meaning it has 7 unique element.
Also B+C=11 elements , but supposing it has 5 overlaps, it would mean it has only 6 unique elements. A+B+C=15. Supposing the overlaps are 11 then it means the unique elements are 4. Ect. So per the example, the best array options with most unique element would be A+B .

I have the following code in the cellmouse event to get information from a selected row.
private void dt_Grid_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
datagrid.Rows[0][0] = dt_Grid.Rows[e.RowIndex].Cells[0].Value.ToString();
datagrid.Rows[0][1] = dt_Grid.Rows[e.RowIndex].Cells[1].Value.ToString();
datagrid.Rows[0][2] = dt_Grid.Rows[e.RowIndex].Cells[2].Value.ToString();
[Code]...
but when i select a collumn, i recive an error because i'm selecting a cell with the mouse and i dont have code for that selection. My question is how can i put an "if" on the beguining of the event so that he can determine if it's a header or not.

How would I go about selecting a subitem in a listview control with just pure Win32 API? I know it's possible with MFC... but I can't use MFC for this project. Right now, when you click on a subitem , it selects only the first column of the row . I used the following by referring internet. But its not working.
HTML Code:
iSlected=SendMessage(hList,LVM_GETNEXTITEM,-1,LVNI_FOCUSED|LVNI_SELECTED);
ListView_SetItemState(hList,iSlected,LVIS_FOCUSED|LVIS_SELECTED,0x000F);

I was wondering if there is a -> simple <- way to overwrite existing text in a masked texbox...
Example: I have a masked textbox, where you can insert dates. That means that you can enter only numbers for the day, month and year.
If I have to do it programmatically, there is no problem... I already have some ideas how I could do something like that, but I would like to know if VS has any parameter or any option I only have to activate.

There was an "impovement" since Windows 7 in algorithm for selecting the initial directory, which is described here OPENFILENAME structure. Briefly:
Windows 7:
If lpstrInitialDir has the same value as was passed the first time the application used an Open or Save As dialog box, the path most recently selected by the user is used as the initial directory. Otherwise, if lpstrFile contains a path, that path is the initial directory.
Otherwise, if lpstrInitialDir is not NULL, it specifies the initial directory. If lpstrInitialDir is NULL and the current directory contains any files of the specified filter types, the initial directory is the current directory. Otherwise, the initial directory is the personal files directory of the current user. Otherwise, the initial directory is the Desktop folder.
The problem that this behavior is not what users of my program expect. Another constraint is that I need to use old CFileDialog dialog, not Common File Dialogs. I've tried to use advises described on StackOverflow and on MSDN. This solution by EllisMiller works perfectly:
Specifying a full path (including filename) in lpstrFile. The filename of course shows up in the filename box which is annoying. I ended up using a filename of "." and adding a bit of code to clear the filename combobox once the dialog is open.
BUT I can't figure how to clear the filename combobox. I've tried to add hook procedure, enumerate windows and clear text, but this didn't work for me. So, my question is: how can I clear text in the filename combobox of CFileDialog?

i`m currently racking my brains out over this issue. How do i go about the x as the first occurrence of the letter?
lets say helxo , x is the 2nd occurrence of l. I will want to change back x into l
i have replaced it with x in the earlier step with this code...
string everySecondChar(const string &s,char source,char distance)
{
string t(s);
for(std::string::size_type even =0,pos=t.find(source,0);pos!=std::string::npos;pos=t.find(source,++pos))
{
[Code]....
i would like to reverse the process now, letting x becoming l again!

Supposed i have a word hammer.
how am i suppose to search for the 2nd occurrence of the letter and then replace it with x?
example hammer will become hamxer
I thought about using replace for it, however i`m lost on how to find 2 occurrences of the same letter in the word.
string formatEncrypt(string message) {
int msgLength=message.length();
for(int i=0;i<msgLength;i++) {
if(message[i] == 'j' {
message[i]='i';
[Code] .....
at line 31 i tried to put a z into the alphabet that occurs twice.
this is what i have done so far
example: hello world
It will turn out as helzlo world
However i want to make the output appear as helzo world

Repeat the vowel Problem 3 (0 / 0)Write a program that will repeat k times each single occurrence of a vowel in the input file "sp.txt" to a new file "output.txt". The first line of the input file contains only the parameter k. The first line (containing the parameter k) should not to be written in the output file.
I wrote the code but i cant figure out something. i read the file, i found the vowels but then i cant print them.
Code:
#include <stdio.h>#include <string.h>
#include <ctype.h>
#define MAX 100
int checkvowel(char c)
