What is the significance of * and - in Format specified?

Question

Please help me to understand this.

Answer 1

You mean format specifier? you can find the answer in the following link:

P.S. Can you please tag a language to narrow down your question scope? any language at some point involves input-output, so it's rather vague.

Answer 2

RGOEWEDKY,
The link I have given contains explanation of asterisk * and hyphen - use cases in format specifier, it works the same way for C and C++ language.

And I suggest you to put 'C-language' on your original question Relevant Tags, to add clarity. Hopefully by then more people come to answer : )

Answer 3

C language
