I need help

Hi, I need help with vectors. I reproduced the errors of my project in the screenshot bellow.

Welcome.

The error is use of undeclared identifier for each of the items in your vector-type, which basically means “I can’t find the variable a” (or b, or c).

Are you sure you’re putting char objects into that vector? :slight_smile:

Thank you very much for your help. Axtually, I had to put apostrophes around each character.
Have a good day

…and in doing so, you have changed the compiler’s interpretation of them from variables (c) to char-type objects ('c'). :slight_smile:
