Sorry, but I really don't have the time to do your work for you; and if I did it would not help as you would still not understand it. Here is a link[^] to some tutorials and other pages to help you. I am sure that if you need it you will be able to find something similar in your own language.

Why don't you try yourself? The above requirements are quite easy to fulfill, just some basic programming knowledge is needed.

The he should move the request to QA: we have the MysticalPowers tag there.

Hello,i study the windows via c/c++.but i have some problems about this routine.
//Wiews must always start on a multiple of the allocation granularity
SYSTEM_INFO sinf;
GetSystemInfo(&sinf);
//Open the data file.
HANDLE hFile = CreateFile(TEXT("C:\\HugeFile.Big"), GENERIC_READ, FILE_SHARE_READ\
, NULL, OPEN_EXISTING, FILE_FLAG_SEQUENTIAL_SCAN, NULL);
//Create the file-mapping object.
HANDLE hFileMapping = CreateFileMapping(hFile, NULL, PAGE_READONLY, 0, 0, NULL);
DWORD dwFileSizeHigh;
_int64 qwFileSize = GetFileSize(hFile, &dwFileSizeHigh);
qwFileSize += (((_int64)dwFileSizeHigh) << 32);
//we no longer need access to the file object's handle.
CloseHandle(hFile);
_int64 qwFileOffset = 0, qwNumOfos = 0;
while(qwFileSize > 0)
{
//Determine the number of bytes to be mapped in this view
DWORD dwBytesInBlock = sinf.dwAllocationGranularity;
if(qwFileSize < sinf.dwAllocationGranularity)
dwBytesInBlock = (DWORD)qwFileSize;
PBYTE pbFile = (PBYTE)MapViewOfFile(hFileMapping, FILE_MAP_READ, (DWORD)(qwFileOffset >> 32), (DWORD)(qwFileOffset & 0xFFFFFFFF), dwBytesInBlock);
//Count the number of 0s in the block.
for(DWORD dwByte = 0; dwByte < dwBytesInBlock; dwByte++)
{
if(pbFile[dwByte] == 0)
qwNumOfos++;
}
//Unmap the view; we don't want multiple views in our address space.
UnmapViewOfFile(pbFile);
//Skip to the next set of bytes in the file.
qwFileOffset += dwBytesInBlock;
qwFileSize -= dwBytesInBlock;
}
CloseHandle(hFileMapping);
i can't understand the qwFileSize += (((_int64)dwFileSizeHigh) << 32);
and (DWORD)(qwFileOffset >> 32), (DWORD)(qwFileOffset & 0xFFFFFFFF)
can you tell me something? thank you.

See the description for GetFileSize()[^].
This code is taking the two result values and creating the 64-bit composite value, by shifting the high order bits 32-bits left, casting the result to an _int64 and adding to the low order value.
_int64 qwFileSize = GetFileSize(hFile, &dwFileSizeHigh);
qwFileSize += (((_int64)dwFileSizeHigh) << 32);
This code is extracting the two 32-bit halves of the value and passing them to the MapViewOfFile() function. In both cases the results need to be cast to DWORDs to keep the compiler happy.
PBYTE pbFile = (PBYTE)MapViewOfFile(hFileMapping, FILE_MAP_READ,
(DWORD)(qwFileOffset >> 32),
(DWORD)(qwFileOffset & 0xFFFFFFFF),
dwBytesInBlock);

Hello all.
I am programming a simple program in win32 console.
#include <stdio.h>
#include <conio.h>
main()
{
int i,j;
char list[80][20];
for(j=0;j<5;j++)
{
for(i=0;i<50;i++)
{
list[i][j]=getchar();
if (list[i][j]=='\n') break;
}
}
for(j=0;j<5;j++)
{
for(i=0;i<50;i++)
{
putchar(list[i][j]);
}
}
}
It should give some char and then print them. but when it want to print some other things (&%^&*vjc) print.

please read the forum guidelines ("how to ask a question"), use PRE tags, ask a specific question and provide symptoms if it does not do as you would like.
Suggestion: If it does not work, start with something simpler; do not enter 20 lines of code if you are not experienced enough to get the first 5 to work as expected.
And do you really want to enter up to 250 characters one by one?

What should I do?
Can you help me on this method...

it is not clear what you want.
it is clear this is one of your very first attempts at programming; if it does not work, start with something simpler.
Do not start with 2-dimensional arrays, until you know everything there is to know about one-dimensional ones.

Im only guessing but..
Look at comments in the code.
Once you press enter, it exits the nested for loop and prints out what you put in.
#include <stdio.h>
#include <conio.h>
int main()
{
int i,j;
char list[80][20]={'\r' };
printf("\n input some chars ..\n\n ");
for(j=0;j<1;j++)
{
for(i=0;i<50;i++)
{
list[i][j]=getchar();
printf("%c = %d ",list[i][j],(int)(list[i][j]) );
if ( (int) (list[i][j]==10) )
{
printf("\n User pressed Enter: new line .. ");
break;
}
}
}
printf("\n\nListing..\n");
for(j=0;j<5;j++)
{
for(i=0;i<50;i++)
{
printf("%c",list[i][j]);
}
printf("\n");
}
printf("\n");
return 0;
}
......

When you create your arrays you're not initialising the contents to anything. Have a look at the rules for initialising automatic arrays in C and you might see what's wrong.
Get in the habit of initialising all variables as you declare them, it'll save loads of tears.
Cheers,
Ash

Since you stop collecting inputs at first newline but then ouput the whole array content, some resulting garbage is inevitable, I suppose.

Hello all.
I want to define an array in c win32 console. First column should be name & family of students and other columns should be grades of them.
NOW HELP ME : How can I have this array with first string column and other columns in float.
Thanks in advance.
|

Create a structure with name and grades as members.
struct _tagStudent
{
char Name[256];
float Math;
float Science;
};Now you can create an array of Students.
struct _tagStudent Student[100];
You can access the members as follows -
Student[0].Name;
Student[0].Math;
Student[25].Name;
Student[25].Science;

how to know the parent item of a child tree item.
and how to traverse from last child item to root parent item.
|
|
|
|
|
1- GetParentItem ( HTREEITEM );
2- you'd loop over the items returned by GetParentItem until the item is TVI_ROOT (or something like that)
Watched code never compiles.

What do you have, i mean where do u struck? do you have HTREEITEM of child?

To Find Parent TreeItem:
call GetParentItem(child tree item)
To Find Root TreeItem:
HTREEITEM child = HTREEITEM of child;
HTREEITEM root = NULL;
do
{
root = GetParentItem(child);
child = root
}
while(root != NULL);
root will contain root tree item
