Exercise 1
Add the greeting.cpp program from your Lab1 folder to the project. Your instructor will show you how to do this. Here is a copy of the source code.
// greeting.cpp
// This program prints a message to greet the user.
#include iostream // Needed to do C++ I/O
#include string // Needed by some compilers to use strings
using namespace std;
int main() {
string name; // This declares a variable to
// hold the user's name
// Get the user's name
cout << "Please enter your first name: ";
cin >> name;
// Print the greeting
cout << "Hello, " << name << "." << endl;
return 0;
}Exercise 2
Read the source code. What do you think the program will display when it is run if the user enters the name Adam on line 12?
Exercise 3
Follow the instructions your instructor gives you to compile the program. You should see a message telling you the program has compiled correctly. This message will be different for each compiler, but may look something like this:

Exercise 5
// average.cpp
// This program finds the average of two numbers.
// It contains two errors that must be fixed.
#include iostream
using namespace std;
int main() {
int size = 0; // The number of values to be averaged
double num1, num2,
average; // Average of num1 and num2
// Get the two numbers
cout << "Enter two numbers separated by one or more spaces: ";
cin >> num1 >> num2;
// Calculate the average
average = num1 + num2 / size;
// Display the average
cout << "The average of the two numbers is: " << average << endl;
return 0;
