Question

Write a program that uses a two dimensional of 256 x 8 to store 8 bit binary representations of each of the characters of ASCII character set.

Answer 1

#include <stdio.h>
#include <stddef.h>
#include <string.h>

#define CHARSET 256
#define BITS 8

int main() {
  int table[CHARSET][BITS] = {0};
  for (size_t i = 0; i != CHARSET; i++) {
    unsigned char value = (unsigned char)i;
    size_t j = BITS - 1;
    while (value) {
      table[i][j] = value & 1;
      value >>= 1;
      j--; 
    }
  }
  for (size_t i = 0; i != CHARSET; i++) {
    for (size_t j = 0; j != BITS; j++) {
      printf("%d", table[i][j]);
    }
    printf("\n");
  }
  return 0;
}
