So I have been out of the game for a little. SO here is something simple yet essential.

#include
using namespace std;

int main ()
{
/* local variable declaration */
int number;
cout << "Input a number: "; cin >> number;
/* check the boolean condition */
if( number < 50 ) { /* if condition is true then print the following */ cout << "That number is less than 50." << endl; } else { /* if condition is false then print the following */ cout << "That number is not less than 50." << endl; } cout << "Value of the number is: " << number << endl; system("pause"); return 0; }

The IF statement checks if the conditions are valid. If it isn't valid then do what's in ELSE.

Simple huh? Yup pretty much. 

OHHH! And just to let you know. Please try to avoid using system("pause") as much as you can. It is a PROBLEM. I only used it to demonstrate the use of the code.

So here is the second code I probably learned a while ago (Years). My initial code when I first figured it out was to convert fahrenheit to celsius. This was pretty plain so I thought I would add the celsius to fahrenheit too! I know right! Then I polished it up and got the resulting code.

// Convert Temperatures from Celsius to Fahrenheit
// and vice versa.

int main ()
{
int option;
float ctemp,ftemp;
cout << "1. Celsius to Fahrenheit" << endl; cout << "2. Fahrenheit to Celsius" << endl; cout << "Choose between 1 & 2: "; cin >> option;
if (option==1)
{
cout << "\t Enter temperature in Celsius: "; cin >> ctemp;
ftemp = (1.8*ctemp)+32;
cout << "\t Temperature in Fahrenheit = " << ftemp << endl; } else { cout << "\t Enter temperature in Fahrenheit: "; cin >> ftemp;
ctemp = (ftemp-32)/1.8;
cout << "\t Temperature in Celsius = " << ftemp << endl; } cout << "Press ENTER to continue..." << endl; getch(); return 0; }

So I'm not going to break it down. most of it is pretty obvious and if it isn't this link might help lol.

Thank for reading :)

Alright guys so there is always a beginning to learning code. This is probably it, Hello World (HW). Those of you who have wanted to learn know that almost every freaking book and resource usually starts with HW. So let me break this short code down.

-What does it do: Displays the text Hello World

// Hello World (The basics)

int main()
{
cout <<"Hello World!"; return 0; }

So before I break this down let me explain something. Some features of C++ are part of the language while others are part of a standard library. This standard library is a compliant body of code that comes with your compiler. So when your compiler puts your program together it links it to the standard library. Before you use the library you need to tell your compiler (declare) your going to use them. This is known as a preprocessing directive.

Lines:

1:  This line is a comment.

3:  Brings in the needed libraries for console output.

4: Keeps you from having to type std::cout each time that output is needed.

6: The main function. It is executed first. 

8: A statement that outputs the words "Hello World"

9: The exit status that states the program returned "0" which means it was successful.

You might have looked around and have seen some HW's return void. This is WRONG! Doing this is just like returning just about any random number that was in a given memory location or register on the computer. This is not cool.

So as you see this program is very simple. I'm not trying to teach, so I'm not going to get into extreme detail on every little thing. This concludes my first post of code. 

Oh and I'm liking the syntax highlighter I added  :-P
