Linux C Programming learning-static Link Library and linux programming static Link At the C language level, code reuse is usually implemented through libraries. In the traditional sense, a library refers to a file ending with the suffix.. Strictly speaking, the function library should be divided into two types: static

, ignoring routing settings for the underlying protocol. (5) returnThe execution successfully returns the number of bytes actually sent, with an error of 1, and the error code is stored in errno.A successful execution simply means that the data is written to the socket's buffer and does not indicate that the data has been successfully sent over the network to the destination.8. RECV () Receive data#include #include ssize_t recv (int conn_fd,void *buf,size_t len,int flags)Recv () is used to

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:

thousand part; If the hour is 0, there are no hundred parts, and if the hour is not 0 and the score is less than 10 points, 10 of the 0 bits are required, and 0 on 10 is not required if the hour is 10 and less than 0 points.Caution: Be careful with cross-day conversions.Input format:An integer that represents the time and minute of the BJT. The number of bits and 10 digits of an integer represents the minute, and the hundred and thousands denote hours. If the hour is less than 10, there is no t

Topic content:Your program reads a series of positive integer data, input 1 indicates the end of the input, and 1 is not the input data itself. The number of odd and even numbers in the data read by the program output.Input format:A series of positive integers in which the range of integers is (0,100000). If input-1 indicates the end of the input.Output format:Two integers, the first integer representing the number of odd numbers in the read data, and the second integer representing the number o

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+

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 within the length of the last word.Output format

Linux C programming practice (2 )?? File System Programming 1. Linux file system Linux supports multiple file systems, such as ext, ext2, minix, iso9660, msdos, fat, vfat, and nfs. At the upper layer of these specific file systems, Linux provides a virtual file system (VFS) for unification... Linux C

Recently tried to do a few. NET core demo, read some source code, feel asynchronous programming in the core has become mainstream, and this piece I have not a systematic summary, so there is this text, next several articles, I will summarize the idea of asynchronous programming, the main reference CLR via C # And good blog posts that I've seen before. The first p

Chapter 3 C ++ Exception Handling Mechanism and rttiI. c ++ Exception HandlingSo far, I have no experience in using the "exception mechanism" in actual projects, so I have no idea about this part. In the qt4 framework, exceptions are not recommended.Interestingly, Google's programming specifications also suggest: "We don't use

1. Backgroundmany times to learn C language has been unable to step into the C language gate, each time in the C language of those system call library functions and so on, but only, Linux system calls need us to remember some irregular structure and some uppercase macro definition and there is a function of various forms such as print fprintf sprintf and so on, l

Important Notes on C ++ programming ideology (I) and key points on programming ideology The most important difference between C ++ and C ++ pointers is that C ++ is a language with higher type requirements. Justvoid *This is eve

Introduction: In the previous topic, a friend left me a message about P2P-related content. First of all, I am not a big fan of C # network programming. Because of the relationship between capabilities, I can only share some of my learning processes with my understanding of some of my learning processes. Next I will go to the topic-peer-to-peer programming.
