 question1.cpp

 #include

using namespace std;

// Entry point of the program

int main()

{

// Get number of students and teachers

cout<< “Input number of students: “;

intnumStudents;

cin>>numStudents;

cout<< “Input number of teachers: “;

intnumTeachers;

cin>>numTeachers;

// Calculate average

return 0;

} 

question5.cpp

 #include

using namespace std;

// Entry point of the program

int main()

{

// Get number of sandwiches and ounces of meat per sandwich

cout<< “Input number of sandwiches: “;

intnumSandwiches;

cin>>numSandwiches;

cout<< “Input ounces of meat per sandwich: “;

doubleouncesPerSandwich;

cin>>ouncesPerSandwich;

// Calculate total ounces needed

doubletotalOunces = numSandwiches * ouncesPerSandwich;

// Calculate in pounds

doubleouncesInAPound = 16;

doublepoundsToPurchase = totalOunces / ouncesInAPound;

// Output result

cout<< “You will need to purchase ” <

return 0;

} 

question8.cpp 

#include

using namespace std;

// Entry point of the program

int main()

{

// Get dental charge

cout<< “How much is the dental charge: “;

doubledentalCharge;

cin>>dentalCharge;

// Calculate cost to pay by customer

doublecoPay = 20;

doublechargeLeft = dentalCharge – coPay;

doubleadditionalPay = chargeLeft * 0.15;

doublemyCost = coPay + additionalPay;

// Calculate cost by insurance

doubleinsuranceCost = dentalCharge – myCost;

// Output result

cout<< “You will pay $” <
