Using the statements you wrote in Exercise 2.4, write a complete program that calculates and displays the product of three integers. Add comments to the code where appropriate. [Note: You’ll need to write the necessary using declarations.]

What will be an ideal response?

```
// Calculate the product of three integers
#include // allows program to perform input and output
using namespace std;
// function main begins program execution
int main()
{
int x; // first integer to multiply
int y; // second integer to multiply
int z; // third integer to multiply
int result; // the product of the three integers
cout << "Enter three integers: "; // prompt user for data
cin >> x >> y >> z; // read three integers from user
result = x * y * z; // multiply the three integers; store result
cout << "The product is " << result << endl; // print result; end line
} // end function main
```
