Not seeing << ??

stardust2552 (30)
I used cout<< in other parts of my code but for some reason it's not seeing it at the one spot and it's the only error I'm getting... Why?

Line 119 is your mistake

You are trying to cout a void function.

just do some text then call resistor.DisplayResistor()

or combine that cout with resistor.DisplayResistor()

here is an example that compiles below. some of the output looks funky though.

Ohhhhh, Duh, Thank you so very much..... When you look at it for so long you start to miss the little things when your not used to doing this. Thank you again!
