おいらもできた。マルチバイト文字セットをつかってくれ
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
int main(void) {
#define BUFSIZE 256
char buffer[BUFSIZE]; unsigned char val = 0; int bitpos, bitnum, i;
while (1) {
printf("\nBit number : 7 6 5 4 3 2 1 0\n" "Bit :");
for (i=7; i >=0 ; --i) printf( ((val >> i) & 1) ? " 1" : " 0");
while (1) {
printf("\n\ninput change bit : ");
fgets(buffer, BUFSIZE, stdin);
bitpos = atoi(buffer);
if (buffer[0] == '.') { return 0; }
else if (isdigit(buffer[0]) && (bitpos >= 0 && bitpos <= 7)) { break; }
puts("\nSorry. Input 0-7 number.\n" "(. is end)");
}
while(1) {
printf("\nSwitch on(1) or off(0) ? : ");
fgets(buffer, BUFSIZE, stdin);
bitnum = atoi(buffer);
if (isdigit(buffer[0]) && (bitnum == 0 || bitnum == 1)) {

break;
}
puts("\nSorry. Input 0 or 1.");
} }
return 0;
