Sure! Here you go. This works perfectly for me and I think you'll find
the code not only very clear to read but quite informative as well!
#include <stdio.h>
#include <stdlib.h>
#define A(x, y) (x) + (y)
#define S(x, y) (x) - (y)
#define M(x, y) (x) * (y)
#define D(x, y) (x) / (y)
const char mem[] = /* Our "memory" */
{
100, 111, 121, 111, 117, 114,
111, 119, 110, 104, 111, 109,
101, 119, 111, 114, 107, 107,
116, 104, 120, 98, 121, 101
};
int main(int argc, char **argv)
{
int i;
for (i = 0; i < sizeof(mem); i += 2)
{
printf("%2.2s: %d + %d = %d\n", &mem[i],
mem[i], mem[i + 1], A(mem[i], mem[i + 1]));
printf("%2.2s: %d - %d = %d\n", &mem[i],
mem[i], mem[i + 1], S(mem[i], mem[i + 1]));
printf("%2.2s: %d * %d = %d\n", &mem[i],
mem[i], mem[i + 1], M(mem[i], mem[i + 1]));
printf("%2.2s: %d / %d = %f\n", &mem[i],
mem[i], mem[i + 1], D((float)mem[i], (float)mem[i + 1]));
}
return(0);
}
