(A and C)
Exercise 1.14. If n and k are integers, define the binomial coeffi- cient (m), read n choose k, by n! if 0 <k <n, = 0 otherwise. k!(n - k)! (a) Prove that ("#") = (m) + (-2) for all integers n and k. (b) By definition, () = 1 if k = 0 and 0 otherwise. The recursion relation in (a) gives a computational procedure, Pascal's triangle, for calculating binomial coefficients for small n. Start with...

C++ ONLY Write a function, int flip(string a[], int n); It
reverses the order of the elements of the array and returns n. The
variable n will be greater than or equal to zero.
Example:
string array[6] = { "a", "b", "", "c", "d", "e" };
int q = flip(array, 4); // returns 4
// array now contains: "c" "" "b" "a" "d" "e"
