怎么把读出来的数据输入txt
我想把读出来的数据全部写到txt上去，怎么实现呢？我写的不行
#include "stdafx.h "
#include <iostream.h>
#include <fstream.h>
#include <stdlib.h>
#include <math.h>
void main()
{
char curve_id[15];
char str[256];
int pulse,i;
double index, vps,wid;
int loss_rate;
int point_num;
unsigned short *pData;
FILE *fp=fopen( "c:\\trace04.dat ", "rb ");
//FILE *fp=fopen( "C:\\Program Files\\Microsoft Visual Studio\\MyProjects\\读数据\\trace01.dat ", "rb ");
if(fp==NULL)
{
cout < < "not exist " < <endl;
}
fread(curve_id,1,14,fp);
fread(str,1,6,fp);
str[6]=0;
pulse=atoi(str);
fread(str,1,6,fp);
loss_rate=atoi(str);
fread(str,1,6,fp);
index=atof(str);
fread(str,1,6,fp);
vps=atof(str);
fread(str,1,6,fp);
point_num=atoi(str);
pData=new unsigned short[point_num];
fread(pData,2,point_num,fp);
for(i=0;i <point_num;i++)
{
cout < < "[ " < <i < < "]= " < <pData[i] < < " ";
}
cout < < "pulse= " < <pulse < <endl;
cout < < "loss_rate= " < <loss_rate < <endl;
cout < < "index= " < <index < <endl;
cout < < "point_num= " < <point_num < <endl;
cout < < "vps= " < <vps < <endl;
wid=0.1*pulse/vps;
cout < < "wid= " < <wid < <endl;
ofstream tfile( "shuju.txt ",ios::binary);
tfile.write((char*)&pData[i],sizeof pData[i]);
}
[解决办法]
ofstream tfile( "shuju.txt ",ios::app);
tfile < < pData;
