Chapter 1
This is just about hello world in CPP
Using this I just want to check if the code highlight is there or not
Adding an image without using height and width

Adding image using img tag with width and height
Center align image

Code
C++ Hello world code
#include<iostream>
using namespace std;
int main(){
cout<<"hello world "<<endl;
cout<<"This is getting some update";
return 0;
}
Add two number
int main(int a, int b) {
// adds and returns the result
return a + b;
}
Note
Do you have any notes.(give 4 space above to show the line in the next line)
This can be collapsed, use collapasable=true
Cpp is awesome! , this is with title, for that we need to use title="some title"
A code segmenent can also be made as a part of admonish block , but in that case the admonish block should be enclosed with ~~~ and code with ```
#include<iostream>
int main() {
return null;
}
Cpp is awesome! , this is with title, for that we need to use title="some title"

Cpp is awesome! , this is with title, for that we need to use title="some title"
Cpp is awesome! , this is with title, for that we need to use title="some title"
Success without title
Adding code from a source code file
#include<iostream>
using namespace std;
int main() {
cout<<"You are welcome to this world!";
}
For nesting code with admonish we can use ````(4) instead of ```(3), as done in the above example

1.1 — Statements and the structure of a program
Chapter introduction
Welcome to the first primary chapter of these C++ tutorials! Dummy md file
In this chapter, we’ll take a first look at a number of topics that are essential to every C++ program. Because there are quite a few topics to cover, we’ll cover most at a fairly shallow level (just enough to get by). The goal of this chapter is to help you understand how basic C++ programs are constructed. By the end of the chapter, you will be able to write your own simple programs.
In future chapters, we’ll revisit the majority of these topics and explore them in more detail. We’ll also introduce new concepts that build on top of these.
In order to keep the lesson lengths manageable, topics may be split over several subsequent lessons. If you feel like some important concept isn’t covered in a lesson, it’s possible that it’s covered in the next lesson.
Statements
A computer program is a sequence of instructions that tell the computer what to do. A statement is a type of instruction that causes the program to perform some action.
Statements are by far the most common type of instruction in a C++ program. This is because they are the smallest independent unit of computation in the C++ language. In that regard, they act much like sentences do in natural language. When we want to convey an idea to another person, we typically write or speak in sentences (not in random words or syllables). In C++, when we want to have our program do something, we typically write statements.
Most (but not all) statements in C++ end in a semicolon. If you see a line that ends in a semicolon, it’s probably a statement.
In a high-level language such as C++, a single statement may compile into many machine language instructions.
1.2 — Comments
ALEX
SEPTEMBER 8, 2023
A comment is a programmer-readable note that is inserted directly into the source code of the program. Comments are ignored by the compiler and are for the programmer’s use only.
In C++ there are two different styles of comments, both of which serve the same purpose: to help programmers document the code in some way.
Single-line comments
The // symbol begins a C++ single-line comment, which tells the compiler to ignore everything from the // symbol to the end of the line. For example:
