// Lab 0 Lecture - Parts of a program

// This is a working source file, so copy and paste the text into 
// your IDE and run it.

// For the rest of the semester you will be downloading source files like 
// this one that will demonstrate the weeks material. Make sure to compile
// and run them to see how the code works (press F9 in Code Blocks). You're 
// encouraged to modify and do your own testing to these programs as well.



// Comments

// You may have noticed that there are two '/' infront of each line so far.
// this is the way you let the compiler know that you are writing comments.
// comments are solely for the programmer to label and make notes about 
// their code. Comments do not affect how your program will run. 

// Another syntax for writing comments is shown below where
// '/*' is the beginning of your comments and '*/' is the end
// as shown below. This can be useful for commenting out paragraphs.

/* 
 * You may find commenting tedious, but it is extremely important to write
 * good comments so that you and others can more easily understand what is  
 * going on. This is especially important when your programs get more complex.
 */



/* parts of a simple C++ program */


// preprocessor directive
#include <iostream>

using namespace std;

// main function declaration
int main()

// opening and closing braces indicate the beginning and end of the 'main' function
{

// statements that do stuff
	cout << "Look, you fool. You've got no arms left." << endl;
	cout << "Yes I have." << endl;
        cout << "Look!" << endl;
        cout << "It's just a flesh wound." << endl;


// Exit the program
	return 0;

}


// A very useful tool that Code Blocks provides is the ability to comment out
// sections of code. You can comment out a section of code by highlighting 
// the code you wish to comment out and pressing Ctrl+Shift+C. Likewise,
// you can uncomment a section of code with Ctrl+Shift+X. Try commenting out
// the above program.

// (In Eclipse Ctrl+/ to both comment and uncomment)
