Answer 2

While comparing two identical strings using strcmp() function, the returned value:

Explanation:

• C comparison functions like int strcmp(char* a, char* b); return zero when the values are equal. A comparison function measures greater than and less than as well as equality.

• So, c.0 is correct.
