即汇总下来，代码可以分为6部分组成，包括：BSS区（未初始化的全局变量/静态变量区）、Data区（实始化的全局变量区）、Stack区（栈区）、heap区（堆区）、Code区（代码区）、const区（常量区）。一、BSS区和Data区 C语言编程中定义的全局变量、静态局部变量，就是分配在全局变量/静态变量区域，但是
Heap Sort Code in Python, Java, and C/C++ Python Java C C++ # Heap Sort in python def heapify(arr, n, i): # Find largest among root and children largest = i l = 2 * i + 1 r = 2 * i + 2 if l < n and arr[i] < arr[l]: largest = l if r < n and arr[largest]...
In aprevious article, I’ve discussed an old (but important) category of memory-corruption vulnerability called “stack buffer overflows”, and how we, as attackers, can exploit these vulnerabilities to take control of a remote program and make it run our shellcode. ...
Code Area(代码区):程序代码指令、常量字符串、只可读。 Static Area(静态区):存放全局变量/常量、静态变量/常量。该区域的大小在程序一加载进内存的时候就已固定,但是静态变量的值是可以更改的。 Heap(堆):由程序员控制,使用malloc...

编译命令:gcc example1.c -o example -l pthread a. Before malloc in main thread 在程序调用malloc之前程序进程中是没有heap segment的,并且在创建在创建线程前,也是没有线程堆栈的。 b. After malloc in main thread 在主线程中调用malloc之后,就会发现系统给程序分配了堆栈,且这个堆栈刚好在数据段之上。说明...
Overwriting the constructor/destructor pointers (if present) might directly lead to code execution (in a fashion similar to what we explained in the “Overwriting Global Structures' Function Pointers” subsection). • Changing the number of objects in the cache might result in some funny allocator...
Hi, I am trying to hardcode some image files into my source code, so I don't have to send the image files with the executable. I am able to declare this array in the program without an error. static const struct imagedata { unsigned int…
