What is the output of the following code snippet? #include #include using namespace std; int main() { int var1 = 10; int var2 = 2; int var3 = 20; var3 = var3 / (var1 % var2); cout << var3 << 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.
