你的猜测基本是对的。cos的三个函数原型如下:double cos ( double x );float cos ( float x );long double cos ( long double x );不接受整数为参数。参考资料:http://www.cplusplus.com/reference/cmath/cos/

include 后面应该有个空格吧 还有现在的C++ 标准头文件名都使用不带 .h 的格式,比如:include <iostream> include <cmath> 顺便加一句 unsing namespace std;

别的电脑上可能可以通过编译,可能是头文件默认目录上iomanip出了问题,写#include<iomanip.hpp>/#include<iomanip.h>/使用其他有相同作用的函数库(如cstdio(头文件#include<cstdio>) 。
#include <iostream> // 输入输出流 #include <vector> // 动态数组 #include <algorithm> // 通用算法(如排序) #include <cmath> // 数学函数 // 根据需要继续添加其他头文件 4. 检查编译设置或代码问题 如果编译器支持<bits/stdc++.h>但仍然报错,可能是因为以下...
