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

gives a rational number in the form of "A1/b1 a2/b2" in a row of two fractions, where the numerator and denominator are all positive integers within the range of int types.Output format:The relationship of two rational numbers is output in a row according to the format "A1/B1-a2/b2". where ">" means "Greater than", "Notice that there is a space before and after the relationship character.Input Sample:1/2 3/4Sample output:time limit: 500ms memory limit: 32000kb1231NetEase Cloud Classroom _c

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

All Chinese and all visualProgramming Language-- "Easy language" The easy language version I downloaded is 3.7. The interface design is similar to VB and compilation speed is fast. The Enterprise Edition can also be compiled into an independent application.Program. Like VB, it provides a lot of visual controls, and the entire interface looks like Chinese. If you

This article describes the C language of the generic programming method, share for everyone to use for reference. The specific analysis is as follows: First, generics programming allows you to write fully generalized and reusable algorithms that are as efficient as algorithms designed for a particular data type. In C, this type of generic

Read some on the internet, You also build the. resources file yourself, and then load it dynamically, this method does not try, it is also very troublesome, originally vs can easily generate. resx resource files, and then compile the DLL together for a long time did not figure out how to read each string separately, but also through other methods to achieve multi-language support, Only one by one regret is the need to restart the program, in fact, thi

We know that in C + + there is a special type of bool used to represent true or false. But there is no such type in C (at least I always think), the value of the expression is 0 false, not 0 is true. So the conditional Judgment statement (if (...), while (...)) Very flexible, even a pointer type can be a conditional expression.To make the program clearer, we often give the following macro definitions: typedef int BOOL; #define TRUE 1 #define FALSE 0 This is the most common form of

Branch Structure Program relational operators and expressions It is often necessary to compare the two-magnitude relationship in a program to determine the next step in the program's work. An operator that compares two quantities is called a relational operator. The following relational operators are available in the C language:> Greater than>= is greater than or equal to= = equals!= is not equal toRelational operators are both binocular operators,

Summary 1. From the procedure implementation process, the program can be divided into three basic structures: sequential structure, branching structure and cyclic structure 2. The most basic unit of execution in a program is a statement. C-language statements can be divided into five categories:(1) An expression statement with a semicolon at the end of any expression constitutes an expression statement, and the commonly used expression statement is

My friend once told a famous operating-system expert that he wanted to design a really good programming language. The expert replied that it was a waste of time, that good language would not necessarily be accepted by the market, and probably no one would use it, because the language's popularity did not depend on it. At least that was the case with the
