Question

what does rn and dn mean in c++ ?

Answer 1

can you give a bit more context please?

Answer 2

it says bool rn

i think it means run so nvm

Answer 3

"bool" is a data type. so "bool rn" is declaring a boolean variable named "rn".
it is very difficult to answer this without more context.
maybe you can paste some of the code here to show what you mean?

Answer 4

thanks for letting me know

Answer 5

Yeah. It seems that 'rn' and 'dn' are simply identifiers, albeit non-descriptive :(
