Comparing 2 strings

A bit long winded but this shows the strcmp function in action . Ideally you should use a function to cut down on code reuse but I think you get the general idea with this example

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");
}
