问题 I had initial apprehensions about posting this question lest it be a duplicate.But even after googling with many keywords,I couldn't find any link on StackOverflow that explains static and dynamic binding for C.There are questions and answers for C++ though,but all involve classes and stuff that are clearly not for C.And the links outside StackExchange were quite dubious. I need to know the rigorous definition and contrast between these two bindings,exclusively in the context of C.I would

问题 I have an Android app that needs to run a custom binary app I wrote. I already built the binary using ndk and packaged it in the apk under res/raw I did something like this to first run the su process. Process process; process = Runtime.getRuntime().exec("su"); DataOutputStream os = new DataOutputStream(process.getOutputStream()); What do I do after this to run the binary from resources? There was another question here that suggested the use of AssetManager but I don't understand how to do it

问题 I want to use the zlib library in my c++ project. So, I have downloaded zlib library( zlib_1_2_8_msvc2015_64.zip ). Then, I have created zlib folder under "C:\Program Files\Zlib" . Then, Extract zlib_1_2_8_msvc2015_64.zip file into "C:\Program Files\Zlib" . After that, I have opened visual studio 2017 and goes to property => C/C++ => general => additional include directories and added that path : "C:\Program Files\Zlib\msvc2015_64" . After that, I have added #include <zlib.h> header file in

问题 I have ran through code that use _ attribute _((section("name")). I understand that for gcc compiler this allows you to tell the linker to put the object created at a specific section "name" (with "name" absolute address declared in a linker file). What is the point of doing this instead of just using the .data section? 回答1: There are many possible uses. [Edit to add note: this is just a sample of uses I've seen myself or considered, not a complete list.] The Linux kernel, for instance, marks

问题 I'm wondering what's the difference between char s[] = "hello" and char *s = "hello" . After reading this and this, I'm still not very clear on this question. As I know, there are five data segments in memory, Text, BSS, Data, Stack and Heap. From my understanding, in case of char s[] = "hello" : "hello" is in Text. s is in Data if it is a global variable or in Stack if it is a local variable. We also have a copy of "hello" where the s is stored, so we can modify the value of this string via
