i gave some links here and others made suggestions also ..
and as of where people learn it in school, it would obviously be a C/C++ course, correct?
i kinda liked the Deitel&Deitel books too for beginners ...

Ok thank-you for the links i have another Very stupid question....How to i run the program eg the oh so famous Hello world:

Code:

// my first program in C++

#include <iostream.h>

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

ok so i wrote that simple thing but it says that i should figure out my compiler before i cont.. So anyone wanna get me a hand with this Thanx!!!!!

Compile the program source

bash2.05$ gcc my_program.c

Run the program

bash2.05$ ./a.out

You may want to get a new book on C++. Try something published within the last year. Your #include <iostream.h> is technically correct but will throw warnings/errors.

you really should use stl iostream it should look something like this

Code:

#include <iostream>
using namespace std;

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

compile and link your program with this command:
'g++ my_program.cpp -o program'

run the program;
./program

stl stands for Standard Template Library.(in case you were wondering)

They're newer than the .h headers, if there is an STL use it rather than the old .h headers.

for example rather than using '#include <string.h>'
you should be using '#include <string>'

Take some classes it will help you a lot more than one of those Sam's teach yourself in 24 hours.

I develop software in C++ where I work. I read the Sam's book, while it gives you a very basic knowledge on how to write small console apps with minimal header files and small classes, you'll still get more out of a class. If you really want to learn C then paying the money for a class is definitely worth it.
