What should c programmers know?
There are many job requirements for programmers, such as large Internet companies, software development companies, etc. all need programs member.
Programmers need to learn:
1. Master data and its conversion, on-machine representation of data, arithmetic and logical operations, and related basic knowledge of applied mathematics;
2. Understand the composition of the computer and the performance indicators of each main component;
3. Master the basic knowledge of operating systems and programming languages;

Essential skills for programmers:
1. Proficient in development tools
As a programmer, you must be proficient in the use of at least two to three development tools. This is the foundation of a programmer.
You need to master basic scripting languages, such as shell, perl, etc., and at least be able to read these script codes.
2. Familiar with databases
Programmers must be proficient in at least one or two databases, must be very clear about the key elements of relational databases, and must be proficient in the basic syntax of SQL.
3. Understand the operating system
If you want to become a true programming master, you need to have an in-depth understanding of the operating system, its memory management mechanism, process/thread scheduling, signals, kernel objects, and system Calling, protocol stack implementation, etc.
4. Requirements understanding ability
Programmers must be able to correctly understand the requirements described in the task order. It should be clear here that programmers should not only pay attention to the functional requirements of the software, but also the performance requirements of the software.
You must be able to correctly evaluate the impact and potential threats of your own modules on the entire project. If a skilled programmer with two to three years of project experience does not understand this, it can only mean that he may be serious. I worked, but I didn’t work hard.
5. Modular thinking ability
As an excellent programmer, his thinking cannot be limited to the current work tasks. He must think about whether the modules he writes can be separated from the current system. It exists and can be used directly in other systems or other modules through simple encapsulation.
This can make the code reusable, reduce duplication of labor, and make the system structure more reasonable. The improvement of modular thinking ability is an important indicator of the improvement of a programmer's technical level.

C language data structure: The data representation of the tree and graph is a hierarchical data structure consisting of nodes. Each node contains a data element and a pointer to its child nodes. The binary tree is a special type of tree. Each node has at most two child nodes. The data represents structTreeNode{intdata;structTreeNode*left;structTreeNode*right;}; Operation creates a tree traversal tree (predecision, in-order, and later order) search tree insertion node deletes node graph is a collection of data structures, where elements are vertices, and they can be connected together through edges with right or unrighted data representing neighbors.

The truth about file operation problems: file opening failed: insufficient permissions, wrong paths, and file occupied. Data writing failed: the buffer is full, the file is not writable, and the disk space is insufficient. Other FAQs: slow file traversal, incorrect text file encoding, and binary file reading errors.

Algorithms are the set of instructions to solve problems, and their execution speed and memory usage vary. In programming, many algorithms are based on data search and sorting. This article will introduce several data retrieval and sorting algorithms. Linear search assumes that there is an array [20,500,10,5,100,1,50] and needs to find the number 50. The linear search algorithm checks each element in the array one by one until the target value is found or the complete array is traversed. The algorithm flowchart is as follows: The pseudo-code for linear search is as follows: Check each element: If the target value is found: Return true Return false C language implementation: #include#includeintmain(void){i

The readdir function in the Debian system is a system call used to read directory contents and is often used in C programming. This article will explain how to integrate readdir with other tools to enhance its functionality. Method 1: Combining C language program and pipeline First, write a C program to call the readdir function and output the result: #include#include#include#includeintmain(intargc,char*argv[]){DIR*dir;structdirent*entry;if(argc!=2){

C language multithreading programming guide: Creating threads: Use the pthread_create() function to specify thread ID, properties, and thread functions. Thread synchronization: Prevent data competition through mutexes, semaphores, and conditional variables. Practical case: Use multi-threading to calculate the Fibonacci number, assign tasks to multiple threads and synchronize the results. Troubleshooting: Solve problems such as program crashes, thread stop responses, and performance bottlenecks.

How to output a countdown in C? Answer: Use loop statements. Steps: 1. Define the variable n and store the countdown number to output; 2. Use the while loop to continuously print n until n is less than 1; 3. In the loop body, print out the value of n; 4. At the end of the loop, subtract n by 1 to output the next smaller reciprocal.

C language functions include definitions, calls and declarations. Function definition specifies function name, parameters and return type, function body implements functions; function calls execute functions and provide parameters; function declarations inform the compiler of function type. Value pass is used for parameter pass, pay attention to the return type, maintain a consistent code style, and handle errors in functions. Mastering this knowledge can help write elegant, robust C code.

Integers are the most basic data type in programming and can be regarded as the cornerstone of programming. The job of a programmer is to give these numbers meanings. No matter how complex the software is, it ultimately comes down to integer operations, because the processor only understands integers. To represent negative numbers, we introduced two's complement; to represent decimal numbers, we created scientific notation, so there are floating-point numbers. But in the final analysis, everything is still inseparable from 0 and 1. A brief history of integers In C, int is almost the default type. Although the compiler may issue a warning, in many cases you can still write code like this: main(void){return0;} From a technical point of view, this is equivalent to the following code: intmain(void){return0;}
