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; 

}
