Two Questions - Return at end of paired data points in CSV file, and how to "break"

I am using the following line to write pairs of data files. I am hoping to create a CSV file.

CODE fprintf(f, "%d,%f", Universe.year, Universe.R); CODE


This simply writes pairs of data on the same line. I'd like pairs of data on individual lines. This means I need to insert a line feed, somehow, perhaps via a character insertion. Could someone please tell me how to do this easily?

Finally, my memory is very vague on C programming. Is the proper means to exit a loop an if then statement containing the term "break"? How would that be implemented?

Thank you!

There isn't just one way to exit a loop.

Code:

---

bool someCondition = true;
for (int i = 0; i < someValue && someCondition; ++i)
{
    if ( I_want_to_exit_early)
    {
        someCondition = false;
        continue;
    }
}

---

or

Code:

---

for (int i = 0; i < someValue; ++i)
{
    // if the loop needs to terminate prematurely
    if ( I_want_to_exit_early )
        break;
  //...
}

Got the line feed to work by adding \n after the float output formatting code. Still need to verify the "break" from loop solution.

Thanks for the "break"!
