I have an x86 boot sector that I can easily use cat boot.s >dev/fd0 or
cdrom to write a master boot record. Now how would one write a small program
in C/C++ to take 512B or 4096 bits to be more exact and write a string of
ascii characters of 1 and 0 using fgetc fputc ? I am guessing string.h would
be needed and of course fstream in C++. Though C++ is soo much simpler than
C C is well know for its low level abilities.
#v+
#include <stdio.h>
int main(void) {
int i = 0, c;
do {
c = fgetc(stdin);
} while (++i<512 && c!=EOF);
fputc('1', stdout);
fputc('0', stdout);
return 0;
}
#v-
Takes 512 bytes of data (unless there was an EOF) and prits string of
scii characters 1 and 0 (a character '1' followed by character '0').
So now, can you say what you really want so that everyone will
understand?
