Thanks guys. You see, I get discouraged, and then I lay off it for some time. The most has been bout...a week during finals at my high school. But then, whenever I think about it, I just WANT to program. I currently don't have a computer that can program. The one I'm using now isn't mine, and I don't have the chance to be on this one as much as I want to. But, do you think just by reading the book C++ Primer and just thinking about the code, would it be helpful?

If that is all you can do due to resource constraints, then yes. But it will be better (and fun) to write the programs out, compile and run them.But, do you think just by reading the book C++ Primer and just thinking about the code, would it be helpful?

I read about C++ for months, and I didn't get a thing. After I installed Dev-C++ and started getting some real experience, I had pretty much mastered the whole book in barely a week.
If Tiger Woods didn't have clubs, or Elvis didn't have a mike, when they were young, we probably will never have heard of them. In every field, practice makes perfect.
Code:#include <stdio.h> void J(char*a){int f,i=0,c='1';for(;a[i]!='0';++i)if(i==81){ puts(a);return;}for(;c<='9';++c){for(f=0;f<9;++f)if(a[i-i%27+i%9 /3*3+f/3*9+f%3]==c||a[i%9+f*9]==c||a[i-i%9+f]==c)goto e;a[i]=c;J(a);a[i] ='0';e:;}}int main(int c,char**v){int t=0;if(c>1){for(;v[1][ t];++t);if(t==81){J(v[1]);return 0;}}puts("sudoku [0-9]{81}");return 1;}
I have a question. In the book, it's talking about rules for Integer Literals. And it says that the value 20 can be written in three ways:
20
024
0x14
How does that work..?
If anyone has the book, please explain to me Section 2.2. It goes straight over my head.

20 -> twenty in decimalIn the book, it's talking about rules for Integer Literals. And it says that the value 20 can be written in three ways:
024 -> twenty in octal
0x14 -> twenty in hexadecimal
You can easily search the Web for an explanation of number bases. You may even have a scientific calculator that can do the conversion for you, and you may have a calculator program on your computer with such functionality. If not, you can write one yourself (but you dont have a compiler?).

If you feel tired of C++, take a break and go look at some other language, like Perl or Python or Scheme (but not PHP). When you go back to C++, you'll feel much more comfortable with it.
Why not PHP? It has no interesting properties that C++ lacks, while Perl, Python, and Scheme do.
