Not is necessary the & and [0].
One problem that i found on CCS, is the function strstr. But i have
implemented!
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:
