AP建立WIFI，接受STA连接，串口数据和TCP互传 include<ESP8266WiFi.hconstcharssid"esp8266_666";constcharpassword"12345678";WiFiServerserver(8266);vo

一文件1.1使用C标准库中的IO库（fstream）读写文件include<iostreaminclude<fstreamusingnamespacestd;intmain(){charszData200"123456tes

include<stdio.hvoidexchange(intarray,intp1,intp2){if(p1p2)return;inttemparrayp1;arrayp1arrayp2;arrayp

C语言使用信号量机制实例：include<signal.hinclude<unistd.hinclude<stdio.hinclude<sys/types.hvoidsigroutine(intsigno){switch(signo){

捕获指定的类型这样的话可以对每种异常做出不同的处理，例如：include<iostreamusingnamespacestd;voidA(intn){inta1;floatb0.2;doublec0.3;

include <iostreaminclude <stdio.husing namespace std;define BUFF_SIZE 20int main (){FILE fp;fp  fopen("epp370p0190_0408.13

1、cincin是C中最常用的输入语句，当遇到空格或者回车键即停止.如：include<iostreaminclude<stringusingnamespacestd;intmain(){        chara\50\;        cina;            

有效进制范围\2,36\;include<cstdioinclude<windows.hintmain(){system("chcp437");for(inti0;i<256;i){switch(i){case0:printf("%03

二话不说，直接上代码了。include <threadinclude <iostreaminclude <mutexusing namespace std;volatile int shared_value  0;volatile int running_count  1

include<sys/select.hinclude<sys/time.hinclude<stdio.hinclude<unistd.hinclude<signal.hintn0;voidoperate(intsig)/定时事件代码
