I know this code for binary search
int search(int a[], int key, int low, int high) {
    if (high < low) {
        return NOT_FOUND; 
    int mid = (low + high) / 2;
    if (key>a[mid]) {
        return searchName(a, key,low, mid-1);
    } else if (key<a[mid]) {
        return searchName(a, key,mid+1, high);
    } else {
        return EXIT_SUCCESS; 
    return ERROR_SEARCH;
Now I want to make recursive one which just need
int search(char *dict, char *name,int length,int compChars)
and length is number element in array.
please help me.
