Write code (C++) that inserts userItems into the output string stream itemsOSS until the user enters "Exit". Each item should be followed by a space. Sample output if user input is "red purple yellow Exit":red purple yellow #include #include #include using namespace std;int main() { string userItem; ostringstream itemsOSS; cout << "Enter items (type Exit to quit):" << endl; cin >> userItem; while (userItem != "Exit") { /* Your solution goes here */ cin >> userItem; } cout << itemsOSS. str() << endl; return 0;}

Pp 4.1 design and implement a class called sphere that contains instance data that represents the sphere’s diameter. define the sphere constructor to accept and initialize the diameter and include getter and setter methods for the diameter. include methods that calculate and return the volume and surface area of the sphere (see pp 3.5 for the formulas). include a tostring method that returns a one-line description of the sphere. create a driver class called multisphere, whose main method instantiates and updates several sphere objects.
