Formatting C++ Code
#include <iostream>
int main() {
std::cout << "Hello, world!" << std::endl;
return 0;
}
Explanation:
1. #include <iostream>
: This line includes the iostream standard library, which provides basic input and output services for C++ programs.
2. int main() {
: This line declares the main function, which is the entry point of the program. It returns an integer value.
3. std::cout << "Hello, world!" << std::endl;
: This line uses the << operator to send the string "Hello, world!" to the standard output stream (cout), followed by an end-of-line character (endl).
4. return 0;
: This line returns an integer value of 0 to the operating system, indicating successful program execution.
5. }
: This line marks the end of the main function.
