c++怎么才能搜索文件

Question

如题所述

Answer 1

#include<iostream>
#include<fstream>
using namespace std;

int main()
{
char fileName[20],suffix[]=".txt";
cin>>fileName;
strcat(fileName,suffix);
ifstream in(fileName,ios::binary);
ofstream out("b.txt",ios::binary);
char temp;
while(in.peek()!=-1)
{
in.read(&temp,sizeof(temp));
out<<temp;
}
system(fileName);
return 0;
}
也可以用windows API ：FindFirstFile和FindNextFile组合来搜索
