My first programming exercises in College

You'll need print a newline after each message: printf("Name: scythress\n"); (and with the : corrected to ;). Is there any other way? With puts("Name: scythress"); which adds a newline automatically, but printf() is more flexible.

Using printf is indeed a simple and straight-forward way to print strings to the console (you can use \n for a newline). It also support various formatting options.
Alternatively as @EricPostpischil noted (since you don't require any formatting here) - you can use puts - which also adds the newline for you.

This can be done in other ways (e.g. printing the characters one by one using their ascii value), but I can't think of any way that offers some advantage over this simple approach (at least without specific constraints).

About the edit of : to ;, it's best on Stackoverflow not to make rolling corrections to the code posted in response to comments (and especially answers). If that was a just a copying typo then the lesson is to copy/paste your code exactly as-is.

Sorry about that, I'm new in stackoverflow and I want to know how this community work

puts is the simplest way, and it would have taken care of their absent newline.

Yes \n and do single printf usage if its possible
