-----BASIC C++ PROGRAM TEMPLATE-----

#include <iostream> 
using namespace std; 
 
int 
main (int argc, char **argv)
{ 
  /* Variable Declaration */ 
 
 
  /* Instructions */ 
 
  return 0; 
} 
------ COMMENTS ---------------

/* 
   Put explanatory messages for yourself and other
   programmers (not the computer) in comments
   like this one 
*/

//single line comments look like this

------EDIT SAVE COMPILE RUN -------------

or EDIT, SAVE, COMPILE, FIX COMPILER ERRORS, RUN, CHECK OUTPUT

1) Edit your code with an editor like emacs or nano (learning to navigate in at least
one editor on polaris is going to be important for this class)

E.g.   emacs -nw myprogram.cpp
       OR
       nano myprogram.cpp

Remember to save you changes!


2) Compile your code with a compiler (translates
human readable source code into executable format
the computer needs to actually run the program)
E.g. g++ myprogram.cpp

Fix any compiler errors! 
Go to first problem by it's line number and fix.

3) Run your program 

E.g. ./a.out

Check that the output of the program is what you expect


-----SIMPLE TYPES-----

TYPE	    EXAMPLES
int	    0,1, -1, 2, -2,...
	
unsigned int  0, 1, 2,3, 4, ...

float	    2.89, 67777799.0
double

char	    'a', 'Z', '\n', '1'

bool	    true, false


string	    "August", "String can hold a whole book or just one letter\n", "a"


possible numeric values are not infinite like in math
- e.g. there is a fixed amount of space to store an int
and so unlike in real like there is a maximum integer

unsigned int vs int - use space to store all positives
    vs half positive and half negative


unsigned and int vs float
     float can store bigger and smaller numbers
     but to do so can give up precision


float vs double - more space used for both bigger numbers
and more precise numbers

"3", '3', 3.0, 3 are all different values!

-----SAMPLE VARIABLE DECLARATIONS------

int month;
char answer;
bool isReady = false;
char initial = 'A';
float wage = 8.50;
string name = "John Smith";
unsigned int year = 1996;

Remember to use descriptive variable names!!
