Sorry, I've been using C++ for so long. Wouldn't the strcmp function do 
the job? Something like this?

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

char str1[3] = "B0";
char str2[3] = "A9";
char str3[3] = "B1";
char str4[4] = "B0";

int result;

void main()
{

result = strcmp(str1,str2);
if (result == 0)
printf("strings are identical\n");
else if(result < 0)
printf("string1 is less than string 2\n");
else
printf("string1 is greater than string 2\n");

result = strcmp(str2,str1);
if (result == 0)
printf("strings are identical\n");
else if(result < 0)
printf("string1 is less than string 2\n");
else
printf("string1 is greater than string 2\n");

result = strcmp(str1,str4);
if (result == 0)
printf("strings are identical\n");
else if(result < 0)
printf("string1 is less than string 2\n");
else
printf("string1 is greater than string 2\n");
}
