使用C语言编写Web服务器，可以通过socket编程实现。以下是一个简单的例子：，，``c，#include，#include，#include，#include，#include，#include，，int main() {， int server_fd, new_socket;， struct sockaddr_in address;， int opt = 1;， int addrlen = sizeof(address);， char buffer[1024] = {0};， const char *hello = "Hello from server";，， if ((server_fd = socket(AF_INET, SOCK_STREAM, 0)) == 0) {， perror("socket failed");， exit(EXIT_FAILURE);， }，， if (setsockopt(server_fd, SOL_SOCKET, SO_REUSEADDR | SO_REUSEPORT, &opt, sizeof(opt))) {， perror("setsockopt");， exit(EXIT_FAILURE);， }，， address.sin_family = AF_INET;， address.sin_addr.s_addr = INADDR_ANY;， address.sin_port = htons(8080);，， if (bind(server_fd, (struct sockaddr *)&address, sizeof(address))< 0) {， perror("bind failed");， exit(EXIT_FAILURE);， }，， if (listen(server_fd, 3)< 0) {， perror("listen");， exit(EXIT_FAILURE);， }，， if ((new_socket = accept(server_fd, (struct sockaddr *)&address, (socklen_t*)&addrlen))< 0) {， perror("accept");， exit(EXIT_FAILURE);， }，， read(new_socket, buffer, 1024);， printf("Message received: %s，", buffer);， send(new_socket, hello, strlen(hello), 0);， printf("Hello message sent，");，， close(new_socket);， close(server_fd);， return 0;，}，``
