Centering strings with printf()

Question

By default, printf() seems to align strings to the right.

printf(\"%10s %20s %20s\\n\", \"col1\", \"col2\", \"col3\");
/*       col1                     


        

Answer 1

There is no printf() format specifier to centre text.

You will need to write your own function or locate a library which provides the functionality that you're looking for.
