Tổng Kết

Như Vậy là đã xong phần cơ ban rồi đó , các bạn chưa hiểu thì tiếp ục tìm hiểu thôi, rèn luyện bài tập trên các trang chuyên về code để tiếp tục biếc đến niềm đam mê nào 

Basic Arithmetic

Arithmetic Operators

C++ supports these arithmetic operators

.Nhìn lên trên bảng thì cũng k cần đọc cũng hiểu là số hỗ trợ các phép tính đấy 🙂

Thêm chút nè:

x += 4 // x = x + 4;

x -=5 // x = x – 5;

Working with variables

 

En:

Declaring Variables

You have the option to assign a value to the variables at the times you declare the variables or to declare it and assign a value later.

Variables

 

En:

Creating a variable reserves a memory location, or a space in memory for storing values. The compiler requires that you provide a data type for each variable you declare.
C++ offer a rich assortment of built-in as well as user defined data types.

Comments

Comments

En:
Comments are explanatory statements that you can include in the C++ code to explain what the code is doing.
The compiler ignores everything that appears in the comment, so none of that information shows in the result.

Printing a Text

New Lines

Two newline characters placed together result in a blank line.

#include

using namespace std;

int main(){

cout << “Hello world ! \n\n”;

cout << “I love programming!”;

return 0;

}

Getting the Tools

En:

Getting the Tools

1.Integrated Development Environment(IDE): Provides tools for writing  source code.Any text editor can be used  as an IDE.

2.Compiler:Compiles source code into the final executable program.There are a number of C++ compilers available.The most frequently used and free available compiler is the GNU C/C++ compiler.

Your First C++ program(Hello World)

En:

A C++ program is collection of command or statements.

Below is a simple code that has “Hello World” as its output

Welcome to C++

En:

C++ is general-purpose programming language.

C++ is used to create computer programs.Anything from art applications , music player and even video games.

C++ was derived from C, and is largely based on it.
