一些程序代码备忘录!
可以生成手机号码的程序,并写入Txt文件.
#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
FILE *pFile;
pFile=fopen("phone.txt","a");
char buf[128];
memset(buf,0,sizeof(buf));
srand( GetTickCount());
int number;
cout <<"请输入需要手机号码的数量:";
cin >> number; char num[128];
memset(num,0,sizeof(num));
int temp;
cout <<"请输入需要手机号码的开头:";
cin>>temp; itoa(temp,num,10);
for(int i=0;i<number;i++)
{
fwrite(num,1,strlen(num),pFile);
for(int x =3;x <=10;x++)
{
itoa(rand()%10,buf,10);
fwrite(buf,1,strlen(buf),pFile);
}
fwrite(" ",1,1,pFile);
fflush(pFile);
}
cout <<"号码生成完毕!"<<endl;
getchar();
return 0;
}
一个服务器带日志的程序代码:
#include <stdio.h>
#include <string.h>
#include <time.h>
int main()
{
FILE *pFile;
char timebuf[128];
char Fnamebuf[128];
memset(Fnamebuf,0,sizeof(Fnamebuf));
memset(timebuf,0,sizeof(timebuf));
time_t stime; time(&stime);
struct tm *today;
char buf[128];
memset(buf,0,sizeof(buf));
today = localtime(&stime);
strftime(buf,sizeof(buf),"%Y-%m-%d",today);
strcat(buf,".log");
pFile=fopen(buf,"a");
strftime(buf,sizeof(buf),"%Y-%m-%d %H:%M:%S",today);
strcat(buf," 服务器启动 /n");
fwrite(buf,1,strlen(buf),pFile);
fflush(pFile);
fclose(pFile);
return 0;
}
select模型 + udp 服务端
#include <iostream>

using namespace std;
