Interestingly enough, but it seems that printf interpreter in Java doesn't leverage "%i" as a format specifier, whereas the latter is aliased to "%d" in C(stdio.h). Also, it does seem that "%n" is treated as format specifier in Java for inserting a new line character compared to completely different intention that it follows in C. int *number = new int(); std::printf("Today%n - ", number); // Today - std::printf("consists of %i letters\n", *number); // consists of 5 letters

In reply to Răzvan MOCANU. @Răzvan thanks. This is what my writing looks like without editing. I fixed all except point 2. I'm not saying they are aligned at the decimal place. I'm saying there are three decimal places

Hi Jeanne! Thank you for posting this material online. I’ve noticed a few small mistakes in the article as I read it, and I thought you might want to fix them.

1. “This post cover a bit about %f (decimal)…” should of course be “This post covers…”;
2. The rendering of the output of the first example unfortunately does not show that the numbers are actually aligned at the decimal place;
3. “From this point, on you do need…” should be “From this point on, you do…”;
4. “…followed by a space and then followed by a boolean…” should be “…followed by a space and then followed by an integer number…”;
5. In the summary, “%2 for new line” should of course be “%n for new line”.
