how to read and write a file use unicode in windows 98??

25-Jan-06 3:47

Instead of accessing the document's member variables directly, you'd be wise to use a "getter" method instead. For example, if the document contained information about a person, it should have method for retrieving that information something like:

class CMyDocument : public CDocument
{
private:
    CString m_strName;
    CString m_strAddress;
    UINT m_uAge;
 
public:
    CString GetName() const;
    CString GetAddress() const;
    UINT GetAge() const;
};

Define "fail."

how does this for loop work!

Why not? What does the code snippet look like that does not work?

can anyone expain this logic flow!i mean the for loop makes no sense to me!...yet it works!and displays the map of india!

#include <stdio.h>
main()
{
int a,b,c;
int count = 1;
for (b=c=10;a="- FIGURE?, UMKC,XYZHello Folks,\

This is the map of india, XORed with some easy key.

putchar ( ++c=='Z' ? c = c/ 9:33^b&1); return 0;

This displays spaces or '!', ++c=='Z' ? c = c/ 9:33^b&1 being the decyphering code.

More in a while...

we have a ?: operator here, so might be seen this way first :

putchar(
    (++c == 'Z') ?
    (c = c / 9)  :
    (33 ^ (b & 1))    // bitwise & AND operator preceedes bitwise ^ XOR operator 
);

T|S~Pn SPm SOn TNn ULo0ULo#ULo-W\
Hq!WFs XDt!" [b+++21];

for each step in this for loop:

1. b is increased by one in [b+++21], so you basically do b=10, b=11, b=12, and so on.

2. a is initialised to the value of the char placed in position b+21 as stated in [b+++21] in the map string.

3. the second for loop is executed. Let's have a closer look:

++c=='Z' ? c = c/ 9:33^b&1

this is equivalent to

if (c==30)
 putchar(c=c/9); // carriage return (next line to display)
else
 putchar(33^b&1);// displays space or !
c++;

following happens in the for loop

3a. a is decreased by one, meaning you stay in this loop (a-64) times
3b. c is increased. If c is equal to 'Z'(=30), a return to carriage is printed, since ++c=='Z' ? c = c/ 9:33^b&1 returns c = c/9, and this is 10.
3c. otherwise, you return 33 Xored with b&1 which is either a space or a '!' char, which prints the map.

when the index b+21 exceeds the string length, the assignement a = string[b+21]is false, leaving the first for loop.

and finally, int count = 1; is of no use Smile | :)

Hope this helps.

What it actually means... !

Is actually:

if (c == 90)

thus dividing by 9 would yield 10, a newline character;

does this work when you don't even define a variable, to assign it a value ?

yes, it will work.

i forget how i worked that thing out, but i think the o gets initialized before its value is ever used for anything meaningful.
