binary search implementation in c in iterative code example
Example: binary search implementation in c in iterative
int iterativeBinarySearch(int array[], int start_index, int end_index, int element){
while (start_index <= end_index){
int middle = start_index + (end_index- start_index )/2;
if (array[middle] == element)
return middle;
if (array[middle] < element)
start_index = middle + 1;
else
end_index = middle - 1;
}
return -1;
}
int main(void){
int array[] = {1, 4, 7, 9, 16, 56, 70};
int n = 7;
int element = 16;
int found_index = iterativeBinarySearch(array, 0, n-1, element);
if(found_index == -1 ) {
printf("Element not found in the array ");
}
else {
printf("Element found at index : %d",found_index);
}
return 0;
}
