C 使用VECTOR从TXT中读取数据.pdf

#include<iostream>
#include<fstream>
#include<string>
#include<vector>
usingnamespacestd;

intmain()
{
vector<float>ivec;
cout<<"请输入要读取的文件名："<<endl;
stringfileName;
cin>>fileName;
ifstreaminFile(fileName.c_str());
if(!inFile)
{
cout<<"文件读取错误！"<<endl;
return-1;
}
inti;//修改成floati;***************
while(inFile)
{
inFile>>i;
ivec.push_back(i);
}
inFile.close();
cout<<"数据读取结果："<<endl;
for(vector<float>::const_iteratoriter=ivec.begin();iter!=ivec.end()-1;iter++)
{
cout<<*iter<<endl;
}
return0;
