Код: Выделить всё
void str2HEX(char * in, char * buffer)
{
while (*in) {sprintf(buffer, "%02X", *in); buffer+=2; in++;}
}
страшная вещь!IfoR писал(а):Ну тогда тут можно поступить разными способами. Например, допустим, пусть будет такая функция:Её в качестве параметра in передаётся исходная строка, а buffer - место для результирующей строки.Код: Выделить всё
void str2HEX(char * in, char * buffer) { while (*in) {sprintf(buffer, "%02X", *in); buffer+=2; in++;} }

Размер буфера легко вычисляется: количество_символов_с_строке * 2 +1Код: Выделить всё
char HEX(char i)
{ return i + ((i>9)?('A'-10):('0')); }
void str2HEX(char * in, char * buffer)
{
while (*in) {*buffer++= HEX(*in / 10); *buffer++= HEX(*in % 10); in++;}
*buffer = 0;
}
