Hello,
I was looking through the code for the strstr function.
I understood all of it except this part:
if (!memcmp(s1,s2,l2))
return (char *) s1;
Wouldnt there be a way to do a similar function without using memcmp? How would it look then?
Thank you. To be precise I'm interested in how would I avoid using memcmp to write a function like strstr.
memcmp is an optimization. You can do the same thing by comparing each char of the string s2 for l2 bytes in s1.

Compilers can produce warnings - make the compiler programmers happy: Use them!

Would I be forced to use strncmp for that?comparing each char of the string s2 for l2 bytes in s1.
No, but that would be one way to solve it. The other solution is to just write your own version of a loop that compares one (piece of) string with another for some number of bytes.
