write in file using printf with variable declared with a phrase
Hi guys, kinda new to unix/linux, could you please help me figure this out.

i need to write in a file using printf.
Code:
printf "%-20s %-40s %-20s\n" $a $b $c >> out.txt

but a, b and c are declared in a header file:
Code:
a='I am a dog'
b='I am a cat'
c='I am a fish'

i want the file to look like this
Code:
I am a dog<10 spaces>I am a cat<30 spaces>I am a fish<9 spaces>

Please help.
