C程序可以编译但不能运行

Question

我已经为作业编写了一个程序，它符合要求，但不执行。我尝试为代码创建新文件，但这没有帮助。过去，当它工作时，项目的一半可以工作，但文件访问部分却无法工作。

这是我执行程序时出现的错误:

执行“D:\Compterprogramming\Project\cass.exe”失败:错误 193:%1 不是有效的 Win32 应用程序。

这是代码:

#include <stdlib.h>

Answer 1

在这个windows文件路径D:\Compterprogramming\Project\cass.exe”中，似乎有一个空格。

因此，它可能无法检测应用程序类型。
