Question

首先，我对我的代码可能废话什么地方对不起，我更多的则是初学者..我试图编译这段代码

#include<stdio.h> 
#include<stdlib.h> 
#include<math.h> 

//initial conditions 
//#define rs0 2.064594102e11 
//#define re0 5.064594102e16 
//#define vs0 2.929599982 
//#define ve0 29295.99982 
#define ms 1.9891e30 
#define me 5.9736e24

我编译它：

Main: main.c 
    gcc -c main.c -o main -std=c99 -lm 

它不创建执行文件，我获得权限被拒绝。

A也试图使用相同的makefiel没有-c ..不起作用，并产生这一堆主题中陈述的错误。帮助=（

Answer 1

所以，至少有2个问题：

1. 如果缩进你的代码，你可以看到你的F()功能缺少一个右括号
2. 不要使用-c在你的编译行。

Answer 2

嵌套函数是不是在C允许的，也就是说，你不能定义里面一个又一个的功能。您要定义main在函数内部

void F(double *y, double t, double* f){..} 

这是错误的。
