WebOct 11, 2024 · Solution: This problem is solved by atan2. It requires both the y and the x separately and therefore can keep the distinction e.g. between 2 positive and 2 negatives etc. In order to use it supply it with the 2 arguments, e.g.: theta = atan2 (*b, *a); Webstd::cout << hypo << " " << a << "\n"; 也就是说，在输出两个数字之后，应该输出一个换行符。 现在我的猜测是，在第一组结果之后，由于代码中缺少一个换行符的输出，您按下回车键将光标移动到下一行，这足以使你的程序崩溃。 florence ms to oxford ms https://ciiembroidery.com
