This code defines a function `print_1_to_n` that attempts to print numbers from 1 to n, but it contains several errors. The `main` function only prints "Hello, World!" and does not call `print_1_to_n`.
- The `for` loop has a semicolon at the end, which makes it an empty loop. The statements after it are not part of the loop body.
- The variable `i` is declared inside the `for` loop, so it is not accessible outside the loop. The `if` statement and `printf` after the loop cannot use `i`.
- The `printf` statement is missing a semicolon at the end.
