natural numbers: For any natural number N, if n is an even number, divide it2. If n is an odd number, multiply it by 3 and then add 1. After a finite operation, we can get the natural number 1. People call this discovery of Gu jiaojingfu a "Gu Jiao conjecture ". Requirement: write a program, input a natural number N on the keyboard, and print the entire process of N after a finite operation. Analysis: the iteration variable is defined as N. According to the content of the grain angle conjecture

questions are: arrange the size, find the maximum value, find the minimum value, and so on, or analyze each number in case of complexity, replace AABA with BBAB. Of course, if you are unfortunate enough to encounter a troublesome pointer problem or a large-sized problem, you will not leave these types regardless of the problem. In the DOS environment, run the EDIT PROG1.ASM command to call up the editing program. EDIT is a text editing program provided by DOS, and PROG1.ASM is the source code f

language is considered a programming language if it is turing complete. as a consequence, HTML and XML are not considered programming languages. this also holds for Data Query Language SQL. SQL is not a programming language because it is, for instance, impossible to write an infinite loop in it. on the other hand, SQL extensions PL/SQL and transact-SQL are programming languages. ASP and ASP. net are also not programming versions ages because they make use of other versions ages such as JavaScri

short-term goal or medium-term goal. There is only one ethereal long-term ideal. This is just like designing. A good design involves many processes from requirement abstraction to code, and coding starts immediately after the requirement is obtained.I am in favor of learning windows first from web development. In the software programming industry, we suggest learning dos, debug, web, and so on first. Then it's easy to implement windows. Of course, I agree that both web and windows are the best.

I first came into contact with programming in high school. At that time, I introduced QBASIC programming in the course. I don't know if anyone was the same as me. after entering the University in 03 years, most of the time the contact was mainly in C. I remember that on the basis of my self-study, I often ran to Microsoft's webcast to download videos to listen to and visit csdn forums, and read blogs in cnblogs (I felt that I was still diligent when I

step, of course, was to teach Anthony how to make a "while"Loop so that you cocould guess a few times. And then after that it tookLittle cajoling to convince him that the gameplay wocould be improved ifYou gave hints like "try a bigger number" or "try a smaller number ".Somehow we got through it all. Before the end of the evening, we had a classic "Guess My number"Game running. The two hours between dinnertime and bedtime had justBarely been enough to get it written and working. We showed it o

interface (Shell), config. sys and autoexec. bat is the configuration file. Under the C:/DOS directory, the IO is first loaded when the application system starts. sys, And then mount msdos according to the configuration file settings. sys and command.com, and then the prompt appears. Now you can enter the command. For example, copy C:/aaa.txt D:/aaa.txt to copy the file. You can also use some applications in the C:/DOS directory to complete the work, such as editing files and writing basic prog

development efficiency is not high in many aspects.It is not that VC is regressing, but that his progress is slow. In many fields, the tool to replace Vc has gradually emerged, and python is fastThe development capability is amazing, and Java also has a wealth of library support. Some small projects originally used VC to do it with them, savingA lot of development time. Microsoft's VC class library has been around for many years. Especially when it comes to Internet functions,Vc has been surpas

A simple loading effect. Four symbols (-, \, |,/) are used to simulate a continuously rotating dashboard, prompting the user that the current loading is in progress, this is what arclive shows when establishing connections for players. The effect is as follows: Loading ...\ JavaScript code:View Source print? 01 To avoid possible blocking of browser threads, setTimeout is used instead of setinterval. It reminds us of the kind of QBASIC
