I am currently reading C++ Through Game Programming, and since my birthday is tomorrow, I thinking of getting some c++ books, or something of that nature and would like to ask for some recommendations.

I'm trying to make a program that takes three scores from the user then averages them, I think I almost have it down except that Im getting an error about not initializing one of my variables but I don't know where the problem lies.

 //Game Score Average
//Program that gets three game scores from user and displays the average

#include <iostream>

using std::cout;
using std::cin;
using std::endl;

int main()
{
	int score1, score2, score3;
	int score4 = score1 + score2 + score3;

	//First score input
	cout << "Enter a number:";
	cin >> score1;

	//Second score input
	cout << "Enter a second number:";
	cin >> score2;
	
	//Third Score input
	cout << "Enter a third number:";
	cin >> score3;

	//Three scores averaged
	cout <<  score4;
	cout << "\n";

	system ("pause");
	return 0;
}

 

 

I have reached an impasse, or what I consider an impasse, I am currently reading Beginning C++ Through Game Programming, Third Edition by Michael Dawson, and I can't read more then a few pages before I have to put it down again. It took me about two weeks just to get through Chapter 1 Types, Variables, and Standard I/O: Lost Fortune.

 

Its not that I'm a bad reader, on the contrary  I read Harry Potter and the Deathly Hollows in a Weeknight front to back, but I just can't seem to read this book. So my question is, can I learn programming from reading and doing the example projects, or should I switch to doing my own projects and referencing to the book and the internet when I reach a problem.

 

This has become a really big problem for me as I'm a very fast learner (I'm Currently taking AP Classes and AICE) and my lack of progress, or what i perceive to be lack of progress, is really frustrating me, and the more frustrated I get the less I want to read the book, and the longer it will ever take for me to master this or any language in general. I would really like some feedback on this issue as I have read some topics on this and still haven't decided by myself.

I wanted to ask if there was some resource out there with concept art, or something similar to it, that could be used for 3D modeling that has a top, side, and front view of the drawing.
