How to write strings as binaries to file? 这是一道C题。我有一个包含字符串的类: classMyClass{public:std::strings;}; 我有一个 MyClass 对象数组: MyClass*array=MyClass[3]; 现在我想将数组作为二进制文件写入文件。我不能使用: Ofstream.write((char*)array,3*sizeof(MyClass)) 因为MyClass 的...
在C语言中,解析二进制文件通常涉及到文件I/O操作和对文件内容的解析。以下是一个简单的示例,展示了如何在C语言中解析二进制文件: ```c #include<stdio.h> #include
整个系统将不得不更加复杂,并且会在运行时浪费宝贵的周期在许多(可能达到数万).text、.data 和其他段之间跳转。 所以,我们将要做的 instead is take each section of the object file and put it together with the same type of section from all other object files. 这个过程称为Relocatable对于对象文件). ...
