I am not familiar with C++ but I can tell you that reading code is always hard.
Sometimes I have trouble understanding what I wrote only a year ago.

Just start with the basics and I'm sure you'll get the hang of it. :)

Bear in mind that PHP and C++ have completely different objectives.
C++ is used to create stand-alone applications. PHP is designed for interactive websites.

I don’t know why most beginners are afraid of C++. They say C++ is hard, but it really is not.
This should get you started.
C++ Info:
http://www.cplusplus.com/doc/tutorial/
http://www.cplusplus.com/
http://www.cppreference.com/
http://en.wikipedia.org/wiki/C%2B%2B
http://www.research....om/~bs/C .html

Visual Studio Express 2008 ( Compiler, IDE )
http://www.microsoft.com/express/vc/
Short program with explatnation, by me:
Code
#include <iostream>

using namespace std;

int main()
{
	// Declare varibles
	double number1;
	double number2;
	double result;

	// prompt user for input
	cout << "Enter number 1: ";
	cin >> number1; // get number1

	cout << "Enter number 2: ";
	cin >> number2; // get number2

	// calculate
	result = number1 + number2;

	// display result
	cout << number1 << " + " << number2 << " = " << result << "\n";

	// main must allway return something
	return 0;
}

Explanation

/* #include is used to include :) a header file
in this case #include <iostream> includes the iostream.h
of standard library -- iostream provide input and output stream
in you program the default is the console window*/

#include <iostream>


/*this will include the std namespace -- namespace is really an
advance part of C++ so i don't want to get into details
you should just know that if you dont't write this statement
you will have to say std::cout, std::cin, std::end,...*/

using namespace std;


/* main is the main entrance to you program -- this is where your
program will start executing all C++ program must have one and only
one main funtion and main must return an int */

int main()
{

/* As you can see this is how you declare a variable datetype
folllowed by an identifier. In this tutorial i used the double datatype.
Here are some more data type: void, int, char, float.
Read a book to learn about Modifiers ( unsigned, signed, long, short )*/

// Declare varibles
double number1;
double number2;
double result;


/* cout is an object of class ostream. cout is used to display text to
the console. Notice that you use the << , extraction operator, to display text */

// prompt user for input
cout << "Enter number 1: ";


/* cin is an object of class istream. cin is used to retrive input from keyboard.
Notice that you use >> , called , insertion operator to get input.*/

cin >> number1; // get number1

cout << "Enter number 2: ";
cin >> number2; // get number2


/* this works just like algebra math, = assigns what ever is in the
right to the varialbe on the left*/

// calculate
result = number1 + number2;


/* Notice how i use the insertion operator ( << ) THIS TIME */
// display result
cout << number1 << " + " << number2 << " = " << result << "\n";


return 0;

Forget about remembering code. Rather, learn the logic and practice using the code. Whatever code you don't remember is the code that you don't use enough. So when you need to use it, just look it up. C++ is my first, and almost only language that I have learned so far. I have touched a little bit of VBScript, and an extremely small amount of HTML.

I have this to say about learning computer languages. Think about things that you want to try to accomplish. Rather then waiting to find magical code that may or may not exist, try and think of ways to reach your goals with the knowledge you already have.

Also, some things in programming will make a lot more sense if you have some basic computer knowledge.
