accepting input filename interactively and using it in C++

[catalina]

I am writing a program where user enters input filename interactively when program runs and my program has to take that user entered string as file name and get data from this file. I know how to use constant file name, but not variable. Please help. Thanks.

Something like this?

char buf[512];
cout<<&quot;Input file name&quot;;
cin>>buf;
fstream stream;
stream.open(buf,ios::in|ios::nocreate);
if(!stream){
     cerr<<&quot;error: could not open file &quot;<<buf;
     exit(1);
}

//then read from the file here just
//as you would read from cin

Is something like this what you were looking for? I'm assuming that this is from the command prompt. Am I correct in this assumption? MYenigmaSELF:-9
