Data combination

Writing a function is as follows, requiring returns from the positive integers of less than B, optional number of number of numbers added and equal to A. Requires writing a definition algorithm. INT func (unsigned int a, unsigned int b) ======================================= ========================================

#include using namespace std; int func (unsigned int a, unsigned int b) {IF ((a <1) || (B <1)) Return 0; IF (((a == 1) || B == 1)) RETURN 1; IF (a > a >> b; cout << Func (A, B-1) << endl; system (" "); Return 0;}
