Mutator Functions

A mutator ("setter") function can apply logic ("invariants") when updating member data.

Exercise: Car Class

In this lab you will create a setter method that receives data as an argument an converts it to a different type. Specifically, you will receive a string as input and convert it to a character array.

1. Create a class called Car.
2. Create 3 member variables: horsepower, weight and brand. The brand attribute must be a character array.
3. Create accessor and mutator functions for all member data. The mutator function for brand must accept a C++ string as a parameter and convert that string into a C-style string (a character array ending in null character) to set the value of brand.
4. The accessor function for the brand must return a string, so in this function you first will need to convert brand to std::string, and then return it.
