c - Best way to compare two int arrays of the same length?

Question

what is the best way to compare int arrays b and c with a:

int a[] = {0,1,0,0,1};
int b[] = {0,1,0,0,1};
int c[] = {1,1,0,0,1};

b and c are just examples, assume they can be any combination of 0s and 1s.

I am trying to detect arrays identical to a. I have googled this for a while and have not found a satisfactory answer.

This is a beginners question I realise, thank you for your patience.

Answer 1

Use the standard memcmp function from <string.h>.

memcmp(a, b, sizeof(a)) == 0

whenever a and b are equal.
