請問這題的Function要怎麼寫!!!感謝題目: Write an overloaded function max that takes either two or three parameters of type double and returns the largest of them. #include <iostream> using namespace std; double max(double x, double y); //PRECONDITION: x and y hold double values //POSTCONDITION: the greater of x and y is returned double max(double x, double y, double z); //PRECONDITION: x, y and z hold double values //POSTCONDITION: the greatest of x, y, and z is returned int main() { double x, y, z; // // Test the two-argument max function // cout << endl << "** Welcome to the max program ** " << endl; cout << "Please enter two numbers" << endl; cout << ">> "; cin >> x >> y; cout << "The max of " << x << " and " << y << " is " << max(x,y) << endl << endl; // // Test the three-argument max function // cout << "Please enter three numbers" << endl; cout << ">> "; cin >> x >> y >> z; cout << "The max of " << x << ", " << y << ", and " << z << " is " << max(x,y,z) << endl << endl; } // -------------------------------- // ----- ENTER YOUR CODE HERE ----- // -------------------------------- // -------------------------------- // --------- END USER CODE -------- // -------------------------------- 提示: You can write the 3-parameter max using an if; e.g., if x is greater than y and greater than z, it's the largest. But an easier way is to make calls to the 2-parameter max -- the max of x, y, and z is the max of two things: (1) x and (2) the max of y and z. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 71.199.79.106
