If used on numeric arrays, strncmp always returns 0. For case-insensitive text comparison, use strncmpi instead of strncmp. Although strncmp shares a name with a C function, it does not follow the C language convention of returning 0 when the text inputs match....
; size_t n = 5; int result = strncmp_ignorecase(str1, str2, n); if (result < 0) { printf("str1 is less than str2 in the first %zu characters (case insensitive). ", n); } else if (result > 0) { printf("str1 is greater than str2 in the first %zu characters (...

The strncmp() function compares two strings up to a specified length.This function is case-sensitive. For case-insensitive searches, use the strncasecmp() function.The following table summarizes the technical details of this function.Return Value: Returns a negative value (< 0) if string1 is ...
