16. Write a program that asks the user to enter two numbers, obtains the two numbers from the user and prints the sum, product, difference, and quotient of the two numbers.

#include <iostream> // allows program to perform input and output
// function main begins program execution
using std::cout; // program uses cout
using std::cin; // program uses cin
using std::endl; // program uses endl
int main()
{
 int number1; // first integer
 int number2; // second integer
 int sum; //holds sum
 int product; //holds product
 int difference; //holds difference
 float quotient; //holds quotient
 cout << "Enter two integers: "; // prompt user for data
 cin >> number1 >> number2; // read two integers from user
 
 sum=number1+number2;
 cout<<"Sum is: "<<sum<<endl;
 
 product=number1*number2;
 cout<<"Product is: "<<product<<endl;
 
 difference=number1-number2;
 cout<<"Dofference is: "<<difference<<endl;
 
 if(number2!=0){
  quotient=(float)number1/number2;
  cout<<"Quotient is: "<<quotient<<endl;
 }
} // end function main
