Anyone know what this means?
i found this encryption code online but i'm not as advanced as the code is so can someone explain to me what is going on in this section. i have included the part of the code i didn't understand.
code-
void decrypt(char *daf)//the decrypting function
{
int decr; //the main int
char x; //the input char
ifstream in; //input stream
ofstream out; //output stream
in.open(daf);//open the inout stream
if(in.fail())
{//see if it's not there
cout<<"Error couldn't open the IN file\n";//print
cout<<"Press \"m\" to return to main menu";
return;//quit
}//END OF IF
cout<<"Enter the OUT file name: ";//ask for the out filename
cin>>daf;//get it
out.open(daf);//open the outfile
in.get(x);//get the input char
if( in.eof() )//IF READING END OF FILE
{
return;//quit
}//END OF IF
while(x!=EOF)
{//while x is not beyond end of file
decr=x+0xFACA;//the dectypring
out<<(char)decr;//print
in.get(x);//get the next char
if(in.eof())//if read beyong the eon of file
break;//break
}//END OF WHILE
return;
}//END OF DECRYPT
i don't understand what the line decr=x+0xFACA means. when i typed the 0xFACA into my program it turned into a special font. not the font of a reserved word, just a different font from the other text. the encryption function is the same as the above line except it says x-0xFACA. any help would be appreciated.
thanks all
