2	A Simple C++ program #include <iostream> using namespace std; // HelloWorld programs originated with the // book “The C Programming Language” main() { cout << “Hello, World\n”; }
3	Scheme Equivalent ;; HelloWorld programs originated with the ;; book “The C Programming Language” (display “Hello World”) (newline)

8	Slightly More Complex #include <iostream> using namespace std; main() { cout << “The answer to the universe\n” << 42; }
9	A New Literal Datatype #include <iostream> using namespace std; main() { cout << “Pi is: “ << 3.14159f << “\n”; }
10	Some Arithmetic #include <iostream> using namespace std; main() { cout << “1 + 1 = “ << 1 + 1 << “\n”; cout << “2 * 2 = “ << 2 * 2 << “\n”; cout << “3 – 5 = “ << 3 – 5 << “\n”; cout << “11 / 2 = “ << 11 / 2 << “\n”; }
11	Conditional #include <iostream> using namespace std; main() { if ((10 % 2) == 0) cout << “10 is even\n”; if (5 % 2) cout << “5 is odd\n”; if ((5 % 2) != 0) cout << “5 is odd\n”; }
12	Variables #include <iostream> using namespace std; main() { int integer_temp = 1 + 1; cout << “1 + 1 = “ << integer_temp << “\n”; float floating_point_temp; floating_point_temp = 1.414f; cout << “Root 2 = “ << floating_point_temp << “\n”; }
13	Scheme Equivalent (let ((integer_temp (+ 1 1)) (floating_point_temp 1.414)) (display “1 + 1 = “) (display integer_temp) (newline) (display “Root 2 = “) (display floating_point_temp) (newline) )
14	Slightly tweaked (let ((temp (+ 1 1))) (display “1 + 1 = “) (display temp) (newline) (set! temp 1.414) (display “Root 2 = “) (display temp) (newline) )
15	Variables #include <iostream> using namespace std; main() { int temp = 1 + 1; cout << “1 + 1 = “ << temp << “\n”; temp = 1.414; cout << “Root 2 = “ << temp << “\n”; }
