1 Word Length (4 points)Topic content:Your program reads a line of text, separated by a space into several words, to '. ' End. You want to output the length of each word in this line of text. The words here are not language-related, and can include various symbols, such as "it's" to count a word, length 4. Note that there may be contiguous spaces in the row.Input format:Enter a line of text in a row to '. ' End, the ending period cannot be counted wit

One of the key decisions that we programmers need to make when embarking on a project is to choose a language, or a set of languages, to implement the system. This decision will not only affect the implementation of the system, but also affect the design. For example, should we use object-oriented or procedural languages? Choosing what language has a profound effect on the life cycle of the project and the

Many people like to argue about what programming language is good, and I think this topic is meaningless if it doesn't limit the scope of application. Each programming language must have its advantages and disadvantages, which also determines the appropriate application scenarios and unsuitable scenarios.In the modern

The original is an article in "Electronic engineer", the following is part of the content excerptThird-generation computer language:Fortran languageIt was mainly used for scientific computation, and the essential difference between it and the assembly language mnemonic was the introduction of the concept of variables. It lays the theoretical foundation of the programming

fraction, and calculate its decimal form. Outputs up to 200 digits after the decimal point, whether or not it can be removed.Input format:Shaped likeA/bTwo numbers, of which 10Output format:Shaped like0.xxxxxxxxxDecimal, up to 200 digits after the decimal point. The output ends with a carriage return with a newline. If A/b is a limited non-repeating decimal, then the output of all the valid bits will be able to, do not need to output the back of the 200-bit full.Input Sample:16/19Sample output:

Topic content:Each non-prime (composite) can be written as a number of primes (also known as prime numbers) in the form of multiplication, and these primes are called the composite's mass factor. For example, 6 can be decomposed into 2x3, and 24 can be decomposed into 2x2x2x3.Now, your program reads an integer in a [2,100000] range, then outputs its mass factorization, and when it reads a prime number, it outputs itself.Input format:An integer that is within [2,100000].Output format:Shaped like:

1 three digits in reverse order (5 points)Topic content:Three-digit number in reverse order:The program reads a positive three-digit number each time, and then outputs the number in reverse order. Note that when the input number contains the end of 0 o'clock, the output should not have a leading 0. For example, enter 700 and the output should be 7.Hint: With%10 can get single digit, with/100 can get hundred number .... The three numbers that are obtained are combined: Hundreds *100+ 10 bits *10+

Welcome to my [QQ space] (http://user.qzone.qq.com/570926881/blog/1477487825)I actually do not have enough qualifications to talk about this problem, in fact, the language actually used is c/c++,php,js.

There are millions of languages in the world, but not only Chinese, English, French and Russian, but also Java, C + +, Python, and PHP. The rapid development of computers has made programming a profession, and programmers have become a profession that has attracted much attention in recent years.Who is the king of language hegemony?In the programming world, there

Transfer statement Statements in a program are usually performed in sequential direction, or in the direction defined by the statement function. If you need to change the normal flow of your program, you can use the transfer statement described in this section. There are 4 kinds of transfer statements in the C language:Goto,break, continue and return.The return statement can only appear in the called function, which returns the keynote function, which we will describe in the function chapter.
