How does this program work?

How does this program work?
We first include the iostream header file that allows us to display output.
➤The cout object is defined inside the std namespace. To use the std namespace, we used the using namespace std; statement.
➤Every C++ program starts with the main() function. The code execution begins from the start of the main() function.
cout is an object that prints the string inside quotation marks " ". It is followed by the << operator.
return 0; is the "exit status" of the main() function. The program ends with this statement, however, this statement is not mandatory.
Note: If we don't include the using namespace std; statement, we need to use std::cout instead of cout.
