You could do that, but in C the name of a string variable is already a
pointer. Thus for a string declared as "char s1[5]", you could pass its
address as either "s1" or "&s1[0]". It's easier to use the former. Thus
strcmp() can be called with:

  intvar = strcmp(s1, s2);

Note that if you wanted to start the comparison from the second character
in both strings, then you would need to declare the addresses
specifically:

  intvar = strcmp(&s1[1], &s2[1]);
