You should be aware that this is C code that you're dealing with, rather than C++.

There is no "C++ window". Are you talking about standard output?

That's my signature. It gets attached to every message I post.

That said, if you Google "c file handling" you will get a lot of very relevant pages.

Don't think in terms of code specifics . Think in terms of breaking the problem down.

You have the file open. What's the next thing you have to do?

No no.

Break the problem down into simpler problems. At this stage of the game, we're not even concerned with the program.

As in, think of the steps to do this without the programming part first. Don't worry about the code, just the method. Write it out as a list in plain English - ie.
1. First, we have to do this
2. Then, we do this.

int main ()
{
char file [50];

FILE * pFile;
pFile = fopen ("bankdatabase.txt","r");
if (pFile==NULL){
printf ("File read correctly but not displayed");
abort();
}

for (int i=0;i<50;i++)
fgets (file,50,FILE);
fputs ("bankdatabase.txt",stdout);
fclose (pFile);
fflush (stdin);
getchar();
return 0;
