C++

Complete the programbelow by writing the function largeDiv that finds thelargest divisor ofa number other than itself. (Hint: try halfof the number first. Then aslong as youhaven't found a divisor, keep subtracting 1 from your trial value. You canbe sure that 1 will divide the numberif you don't find a larger divisor.) #include using namespace std: // Write your function prototype for largeDiv here int main() int number; int divisor; cout "; cin >>number divisorlargeDiv( number) if ( divisor =-1 ) else cout
