TASK 4: Write, compile, and execute the following program: This example shows the recursive definition of the function multiply that takes as input a real number (A) and a real number (B) and returns AB Note that: A0 or BO=0. A1 = A. B*1=B A*B=A+(A*(B-1)). #include using namespace std; double multiply(double A, double B); int main() { cout
