为什么文件会打不开

#include <iostream>
#include <fstream>
#include <cstring>
using namespace std;
/* run this program using the console pauser or add your own getch, system(“pause”) or input loop */
int main()
{
ifstream infile;
ofstream outfile;
char name[20];
char c;
cout<<“please enter filename”<<endl;
cin>>name;
infile.open(name);
if(!infile)
{
cout<<“can not open”<<endl;
exit(1);
}
cout<<“start copy”<<endl;
strcat(name,”copyfile”);
outfile.open(name);
if(!outfile)
{
cout<<“can not copy”<<endl;
exit(1);
}
while(!infile.eof())
{
infile.get(c);
outfile<<c;
}
cout<<endl;
infile.close();
outfile.close();
return 0;
