Scan an array using strcmp

I'm wondering if there's a way you can scan an array for a match using strcmp. I know the parameters passed to strcmp are C strings. So something like this wouldn't work:

strcmp(arrayofstrings[x], c-string)

If you're trying to search the entire array, rather than just comparing two elements, you will need a loop.

const int N = 10;
const char * desired = "desiredString";
char * arrayOfStrings[N];

// You should initialize the elements
// in arrayOfStrings[] before searching

// Searching an unsorted array is O(N)
for(i = 0; i < N; i++)
{
    if(strcmp(arrayOfStrings[i], desired) == 0)
    {
        printf("Found %s.", desired);
        break;
    }
}

It would work as long as the arguments can be reduced to of type const char*.

char *a[] = { "Hello", "Hello" };  // Array of pointers to c strings
if ( !strcmp(a[0],a[1]) ){
    // true in this case
}
