请问这段ida代码怎么反汇编呢
下面这段代码。怎么能想个办法，运行一下，看下参数啥的，方便看算法 具体是啥样的呢？ 多谢各位了__int64 __fastcall main(int argc, char** argv)

这就已经是反出来的C代码了，你还想要啥……
您看。我就想放到vs里能跑。这样我不是能看看。每一步怎么执行的，参数变化是啥。我能给点参数把算法逆向出来是不。哥，给瞧瞧成不 这就已经是反出来的C代码了，你还想要啥…… Deuez 发表于 2020-8-14 20:10
IDA只能反编译成这样
这样的c语言伪代码已经够好看了的。
ida 可以动态调试 一段 伪代码？ 能看传参啥的之类的么？ Deuez 发表于 2020-8-14 20:10
