WebArithmetic with a pointer to void as in. check = (void *) (base + (size * length)); is a GNU extension and not portable. You should replace it by. check = (void *) ( (char *)base + (size * length)); In the case result < 0 you continue searching in the second half of the array including the element that was just tested. WebLinear search in C to find whether a number is present in an array. If it's present, then at what location it occurs. It is also known as a sequential search. It is straightforward and works as follows: we compare each element with the element to search until we find it or the list ends.
