Explanation: 1. The "#include" directive is used to include the necessary header files for the program, iostream and list. 2. The "int main()" function is the entry point of the program. 3. "std::list myList;" declares a list named "myList" that stores integers using the "std::list" container from the C++ Standard Library. 4. "myList.push_back(10);" adds the integer value 10 to the end of the list. 5. "myList.push_back(20);" adds the integer value 20 to the end of the list. 6. "myList.push_back(30);" adds the integer value 30 to the end of the list. 7. "std::cout << "Elements in the list: "; " outputs the text "Elements in the list: " to the console. 8. The "for" loop iterates over each element in the list using an iterator. The iterator "it" is initialized to the beginning of the list using "myList.begin()", and the loop continues until "it" reaches the end of the list using "myList.end()". 9. "std::cout << *it << " "; " outputs the value of the current element pointed to by the iterator "it" to the console. 10. "std::cout << std::endl;" outputs a new line character to the console. 11. "return 0;" ends the main function and returns the value 0 to indicate successful execution of the program.
