programming language should I learn?If you are a Windows administrator, then learn HTML and PowerShell. If you are a Linux administrator, learn HTML and bash scripts.In the IT industry, you don't need to learn to program to make a lot of money: with an enterprise-class technical certificate or qualification, the salary of the programmer is similar and sometimes even better. But knowing how to write bash sc

Wang Yin: How to master the programming languageLearning programming language is the only way for every programmer. But there are too many programming languages in the world, each claiming to have the latest "features." So the trouble with programmers is that they always need to learn all kinds of strange

Topic content:Your program is going to read an integer in the range [ -100000,100000]. Then, use Hanyu Pinyin to output each bit of this integer.If you enter 1234, the output:Yi er san siNote that there is a space between the pinyin for each word, but there is no space behind the last word. When a negative number is encountered, add "fu" at the beginning of the output, such as the 2341 output as:Fu er san si yiInput format:An integer that ranges from [ -100000,100000].Output format:The pinyin th

0 1 Bits value 32 16 8 4 2 1 Your program reads a nonnegative integer, the range of integers is [0,1000000], and then calculates the binary number that represents the parity by the above algorithm, outputting its corresponding decimal value.Tip: The integer is decomposed from right to left, the digits are added 1 at a time, and the binary value is multiplied by 2.Input format:A nonnegative integer in which the range of inte

2Finish (5 points)Topic content:The factor of a positive integer is all positive integers that can be divisible by it. And if a number is exactly equal to the sum of factors other than itself, this number is called the end number. For example 6=1+2+3 (6 of the factor is the one-to-be).Now you are going to write a program that reads two positive integers n and M (1Tip: You can write a function to determine whether a number is complete.Input format:Two positive integers, separated by a space.Outpu

hyphens in the input data.Input format:An article in English.How do I know that the input is over? If you use scanf, it will return the value of several variables read this time, and when this value is less than the number of variables you require to read, the input ends; If you use GetChar, it returns EOF at the end of the input. Output format:11 numbers, followed by the number of words and the number of words containing 1 to 10 letters, separated by a space, with no spaces a
