Using 'For' with fprintf/fscanf

Hello.
My question is the following, I want to save in a file / read from a file, an entire vector with different values in each position. But, if it is a very long vector... instead of doing something like this:

Code:

fp = fopen ("Datos.txt","w");
fprintf (fp, "%d %d %d %d %d ", vector[1], vector[2], vector[3], vector[4], vector[5]);
fclose (fp);

But if we're talking about a really long vector, it can become tedious.
Maybe there could be done something like:

Code:

for(f=0;f<6;f++)
{fprintf(fp,"%d",vector[f]);

I know it's wrong, it's to give a general idea. Any help is apreciated.

Is there any reason you chose to use C-style I/O over more C++ style I/O?

How is it wrong?

Pedantically, your for loop prints out 6 values rather than 5

It also does not include a space between the numbers, but you could easily fix that by doing "%d " rather than "%d"

Yes, currently, lack of time to study c++. (Just realised I posted it on C++ forum, sorry for that.)
But is it really better or simpler in C++? I mean, C one is pretty much simple.

Well apparently I was typing something in a wrong way because I re-checked and it does work.

I appreciate the help guys. Thanks.

Since this was posted in a C++ forum it is worth noting that, in C++, the solution is arguably simpler than in C (assuming included appropriate headers). For example, to output the first five elements of an int array named myarray to an ostream named out, with a space after each element .....

Code:

   std::copy(myarray, myarray + 5, std::ostream_iterator<int>(out, " "));
