Getting Started with C++: Early Objects, 10th Edition PDF
I remember my first day learning C++. I was so excited to dive into the world of programming, but I quickly realized that it wasn’t going to be as easy as I thought. The syntax was confusing, the concepts were abstract, and everything seemed to be going over my head. I was about to give up when I found the 10th Edition of Early Objects. This book was a game-changer. It broke down the concepts of C++ into manageable chunks, and it made learning the language almost enjoyable.
If you’re interested in learning C++, I highly recommend starting with Early Objects. It’s a great book that will give you a solid foundation in the language. And if you’re looking for a PDF version of the book, you can find it here.
Installing Essential Software
Before you can start coding in C++, you’ll need to install a compiler. A compiler is a program that converts your C++ code into machine code that your computer can understand. There are many different compilers available, but I recommend using GCC or Clang. These compilers are free and open-source, and they work on a variety of platforms.
Once you have a compiler installed, you can start writing C++ code. You can use a simple text editor like Notepad or vi, or you can use a more advanced IDE like Code::Blocks or Visual Studio. Whatever editor you choose, make sure that it supports C++ syntax highlighting.
Your First C++ Program
Now that you have a compiler and an editor, you’re ready to write your first C++ program. Here’s a simple program that prints “Hello, world!” to the console:
#includeusing namespace std;
int main() cout << "Hello, world!" << endl;
return 0;
To compile this program, open your terminal and type the following command:
g++ hello.cpp -o hello
This will create an executable file named hello. You can run this file by typing the following command:
./hello
This will print “Hello, world!” to the console.
Basic Syntax
C++ is a statically-typed language, which means that you must declare the type of each variable before you use it. The basic syntax for declaring a variable is:
type variable_name;
For example, the following code declares a variable named i of type int:
int i;
You can also initialize a variable when you declare it. For example, the following code declares a variable named j of type int and initializes it to 10:
int j = 10;
C++ is a free-form language, which means that you can put spaces and newlines wherever you want in your code. However, it is good practice to use consistent indentation to make your code more readable.
Data Types
C++ has a variety of data types, including:
- int: Integer
- float: Floating-point number
- double: Double-precision floating-point number
- char: Character
- string: String of characters
- bool: Boolean value (true or false)
You can use these data types to declare variables, constants, and function parameters.
Operators
C++ has a variety of operators, including:
- Arithmetic operators: +, -, *, /, %
- Comparison operators: ==, !=, <, >, <=, >=
- Logical operators: &&, ||, !
- Bitwise operators: &, |, ^, ~, <<, >>
You can use these operators to perform various operations on variables and constants.
Control Flow
C++ has a variety of control flow statements, including:
- if-else statements
- switch statements
- while loops
- do-while loops
- for loops
- break statements
- continue statements
You can use these statements to control the flow of execution in your C++ programs.
Functions
Functions are reusable blocks of code that can be called from anywhere in your program. Functions can be used to perform a variety of tasks, such as input validation, data processing, and output formatting.
To declare a function, you must specify the return type, the function name, and the parameter list. The return type is the type of data that the function will return. The function name is the name of the function. The parameter list is a list of the parameters that the function will accept.
Here is an example of a function that calculates the area of a circle:
double area_of_circle(double radius) return M_PI * radius * radius;
This function takes one parameter, the radius of the circle, and returns the area of the circle.
Conclusion
This is just a brief overview of the basics of C++. To learn more about C++, I recommend reading the Early Objects book or taking a C++ course.
