Understanding the Code: Differentiating Between Process and Program in C++

I'm studying the concepts of processes and programs in C++ on this site and came across the following code snippet:

#include <iostream>
#include <cstdlib>

int main() {
 std::cout << "Hello, World!" << std::endl;
 return EXIT_SUCCESS;
}

While the code is a classic "Hello, World!" example, I'm struggling to grasp the distinction between a process and a program, especially in the context of this code. Can you explain how this C++ code represents both a process and a program? Additionally, could you highlight any specific elements in the code that demonstrate these concepts?
