Re: For-loop from C to Delphi

Thare are these functions:

Code:
int ctoi(char source)
{ /* Converts a character 0-9 to its equivalent integer value */
   if((source >= '0') && (source <= '9'))
      return (source - '0');
   return(source - 'A' + 10);
}

char itoc(int source)
{ /* Converts an integer value to its hexadecimal character */
   if ((source >= 0) && (source <= 9)) {
      return ('0' + source); }
   else {
      return ('A' + (source - 10)); }
}
StrToInt working. But I'm still confused, what difference between ctoi() and atoi() if char in C is byte? You told C.atoi() = Delphi.StrToInt(), the same doing ctoi()?

Code:
s = "C++";
i = atoi(s[0]);
i = ctoi(s[0]);
i = s[0];
What values are assigned to i in these cases?

Delphi-Quellcode:
s = 'C++';
i = Ord(s[0]);
i = StrToInt(s[0]);
i = Ord(s[0]);
?
