after running! big[] "copy" the string "to small[", the results can be imagined. The extra-long data drowns out the memory areas beyond the array, and unpredictable results can occur! The art of buffer overflow attacks is to "turn unpredictable consequences into the results we want!" "For more detailed information about "buffer overflow", please refer to network resources.The following is a debugger to go through the overflow of the program inside to find out.To better demonstrate how the overf

Switch between user stack and kernel stack in case of interruption

If the task is in the user State when an interruption occursCodeIf the CPU is interrupted, the CPU privilege level changes from 3 to 0. At this time, the CPU will run the switch operation from user-mode stack to kernel-mode stack. The CPU obtains the segment selection and offset of the new stack from the task status segment TSS of the current task. Service Interr

Stack and stack size

The executing program maintains a master stack for the initial (or primary) thread that executes the program, and maintains a different stack for each dependent thread. A stack is a temporary memory address space that retains parameters and automatic variables during a subroutine or function reference call. If the size of the thread

Interview Questions: Use One stack to roll back the number in another stack

Question: There are two identical stacks A and B. Stack a Stores numbers from large to small: 1, 2, 3, 4, 5, and the stack top is the minimum number 1, stack B is empty. Instead of using other data structures, we need to reverse the numbers in stack a so that the number of top Stacks is up to 5. Solution: This questi

Java stack (stack) and heap

Java stack vs heap (heap)1. ConceptStacks and heaps (heap) are places that Java uses to store data in RAM. Unlike C + +, Java automatically manages stacks and heaps, and programmers cannot directly set up stacks or heaps.Stacks, heaps of data structuresStacks are like buckets or chests of data.It is a data structure with a last-in-first-out nature, that is, after the storage of the first fetch, the first storage after the fetch.It's like we're going t

This is the rain markArticleThe original Article is here. Concerning the CLR memory management mode, various books and network articles are held in different words, which is very confusing. In most cases, we only mention "managed heap" and "stack" in general. The actual process is very complicated. Since there is no unified statement, I cannot guarantee the accuracy of this article.

IOS: Understanding of Heap and stack (stack)

The Object-c object allocates memory space in memory as a heap, and the heap memory is released by you, that is, release1. stack : The compiler automatically allocates releases, stores the function's parameter values, and local variables are equivalent. It operates in a manner similar to a stack in a data structure.2. Heap area : typically released by programmers, if the programmer does not release it, it m

Stack and stack

A program is generally divided into three segments: Text, data, and BSS.Text: it refers to the program code. It is determined during compilation and is read-only,Data Segment: data that can be determined at the compilation stage rather than the runtime, readable and writable.It is usually referred to as the static storage area. The global variables and static variables assigned with the initial values are stored in this area, and the constants are also stored in this area.BSS segment: defines gl

What is a stack? What are the two ways the stack works?

A stack is such a data structure. It creates a storage area in memory, in which the data is deposited in one order (i.e., "--push") in this area. There is an address pointer that always points to the data unit of the last data pressed into the stack, and the register that holds the address pointer is called the stack indicator. The unit that starts putting the da
