See GOTW #one hundred and cppreference for that trade-offs and additional implementation details connected to this idiom.

Normally you have to incorporate and remove features with the container, so use vector by default; if you don’t will need to switch the container’s sizing, use array.

An interpreter executes directly the significant amount language. It really is interactive but runs slower than compiled code. Many languages may be compiled or interpreted.
