私はそれらをJavaで使用していて、それほど多くの問題はないようですが、C++ではあまりよく理解していません。割り当ては次のとおりです。
Write a class named Car that has the following member variables:
year. An int that holds the car's model year.
make. A string that holds the make of the car.
speed. An int that holds the car's current speed.
In addition, the class should have the following member functions.
Constructor. The constructor should accept the car's year and make
as arguments and assign these values to the object's year and
make member variables. The constructor should initialize the
speed member variable to 0.
Accessors. Appropriate accessor functions should be created to allow
values to be retrieved from an object's year, make, and speed
member variables.
accelerate. The accelerate function should add 5 to the speed member
variable each time it is called.
brake. The brake function should subtract 5 from the speed member
variable each time it is called.
Demonstrate the class in a program that creates a Car object, and then
calls the accelerate function five times. After each call to the
accelerate function, get the current speed of the car and display
it. Then, call the brake function five times. After each call to
the brake function, get the current speed of the car and display it.
これまでのところ、これは私が持っているものですが、私は完全に間違っていると合理的に確信しています。誰かアドバイスがあれば本当にありがたいです、ありがとう!

PS:メインは0を返します。純粋に「取得して設定」すること全体を理解しようとするプレースホルダーとして。
