Thread: Binary Output

Does anyone know how to output in binary without me having to write a converter myself, it needs to convert text / numbers / ... yeah thats about it.

Any Help would be apreciated...!

All of the things that i want to output are stored in variables but for some examples



Suan //first name
Seith //Last name
12 //Strength
13 //...
15 //...
13 //...
10 //...
67 //hp
85 //maxhp
12 //mp
12 //maxmp

why do you need to output it as binary?

I'd just like it so that no one can change their savefile without atleast going through some trouble of converting into readable text and even then some people are to dumb to evern think of converting the binary to normal text.

when I want to do that, I usually just shift the characters (using the ASCII table) by a random number of positions and put that number somewhere in the file, for example:

Code:

int RANDNUM=1+rand()%100;  //any number between 1 and 100

ofile<<"N"<<RANDNUM<<":"<<flush;  //output the number at the beginning of the file

for(...)  //loop through all characters (including spaces, newlines, numbers, etc.)
    ofile<<static_cast<char>(static_cast<int>(THISCHAR+RANDNUM));  //shift and write the chars

now the file will look something like this (assuming the random number was 56)

Code:

N56:¸Ïj¦ô°X·Ìx#‚:T;t4I™÷6æÜäg¯j½Ék”ƒa8|ž]I~DSCûÀSÚµ¦“t“}¬{¡\{0.H8¨¾€Ý˜õ<tÏQM+×c�

now when you read in teh file, discard the N, read in the number (56 in this case), discard the colon (, and start reading in the characters, decrementing each by the number you just read in... This should in now way be considered 'secure', but it's just something to keep the average user from fking around with the file... although it probably won't do much... another thing you could do is save it as .ico or something, so people might think it's an icon and not touch it... but I wouldn't go that far...

one thing I would do though, is supply a way to edit the savefile, but keep it somewhat secure... maybe through a password or something, but sometimes it becomes necessary to backup/restore/edit a file...

You could use the bitset stl class. Its contructor accepts a long. There is the << operator overloaded for stream, but I do not know how the output should like.

... or you could read the FAQ...
