FeelingsJust beginning to touch Java, feel both confused and hard, because they have not been in a self-learning way to contact a new programming course, long time to find more difficult. I think, teacher and student relationship is eldest brother and brother! Why do you say that, because the teacher experienced the student age and more understanding of the situation of students, leading students to learn and impart some experience, so that students less detours, and exchange ideas with students

solutionissue: After you open HyperTerminal, The information on the arm machine is never displayed in the HyperTerminal window. solution: Found the reason, is the serial cable connected to the wrong location, should not be connected to 1, after replacing 0 , HyperTerminal will show normal. (2)IP problems and Solutionsproblem: Need to put the lab box, virtual machine the IP of Redhat,WinXP is set to the same network segment. FIX: First look at the lab box's IP Address, set the other two addresse

exception. The typical errors are:scanf("%d",val); (2) Read uninitialized memory Although the bass memory location is always initialized to 0 by the loader, it is not the case for heap storage. A common mistake is to assume that the heap memory is initialized to 0. (3) Allow stack buffer overflow If a program writes to the target buffer in the stack without checking the size of the input string, the program will have a buffer overflow error. (4) Assume t

Summary of the learning contents of the textbook fourth Chapter processor Architecture Y86-64 instruction set architectureThe "programmer" here refers to the person who writes the program with the assembler code, or the compiler that produces the machine code . The state of y86-64 is similar to x86-64.Y86-64 directive X86-64 's MOVQ instruction is divided into 4 different instructions: IRMOVQ,RRMOVQ,MRMOVQ,RMMOVQ, which explicitly indicates the source and destination format, and the source

shift x>>k: Move the K-bit right and the value at the left to complement K's most significant bit Logical right Shift x>>>k: Move K-bit right, left complement K 0 Use arithmetic right shift for signed number, logical right shift for unsigned numberInteger representation Information = bit + context unsigned integer: b2u4[0011]=0 2^3+0 2^2+1 2^1+1 2^0=3 Signed integer-complement code: B2t4[1011]=-1 2^3+0 2^2+1 2^1+1 2^0=-5 Unsigned number means you need to append the suf

Integers and floating-point numbers indicate the relationship of the same number:P74: The relative region corresponds to the low of the integer, just before the highest significant bit equal to one stop, and a floating point repre

development efficiency of the software. Make is a command tool that is a tool for Makefile commands in a timely manner.The most important and basic function of make tools is to automate compiling and maintaining multiple source files according to the relationship between source programs described in the makefile file. While the makefile file needs to be written in a certain syntax, the file needs to explain how to compile the individual source files and link them to the executable file, which r

expressed in the desired floating-point form.1. Rounding to even numbersRounds a number up or down so that the lowest effective number of the result is even.2. Rounding to 03. Rounding up4. Rounding Down34 you can see the upper bound.Rounding to even gets the closest match.4. Floating-point arithmeticFloating-point addition: exchangeable, non-associative, satisfying monotonicityFloating-point multiplication: exchangeable, non-associative, non-assignable, satisfies the following monotonicityFloa

)That is, the number is rounded up or down, and the lowest valid number of the result is even.Can be used in binary decimals.2. Rounding to 0That is, rounding down integers and negative numbers rounded up.3. Rounding DownBoth positive and negative numbers are rounded down.4. Rounding upBoth positive and negative numbers are rounded up.Iv. floating-point arithmetic 1. floating-point addition Floating-point addition is exchangeable Floating point addition not binding The floating-

If the NEWFD is already open, Dup2 will close NEWFD before copying the OLDFD.#include int dup2(int oldfd,int newfd);8 Standard I/OThe standard I/O library models an open file as a stream, which is a pointer to the structure of the file type.#include *stdin; /*标准输入，文件描述符为0*/extern FILE *stdout; /*标准输出，文件描述符为1*/extern FILE *stderr; /*标准错误，文件描述符为2*/A strea
