你好这是我的第一个c项目，我有一些语法erorrs我叮当，它不能被编译？请向我解释我的恐怖分子在哪里？代码无法编译

我使用Visual Studio 2010编写我的代码。

而且我用的指令是：

#include <stdio.h> 
#include <conio.h> 
#include <string.h> 
#include <stdlib.h>

这是编译器erorr：

编译器产生的粘贴错误也... –

我已经从编译器粘贴了erorrs。 – kirokrio2

我建议您让Visual Studio编辑器为您缩进代码。（按Ctrl-k，Ctrl-d缩进整个文档。） – molbdnilo

您正在使用的语句的功能外（for(a = 0;a < 100;a++)高达int main()）。这是不合法的C.

编译器不知道函数magic - 包括正确的头文件或将其声明/定义添加到编译源。

另请注意，你的代码既没有声明a也没有arr1，后者可能还需要内存分配（查看编译器消息，但声明不包含在您发布的代码片段中）。
