Question
Problem Statement:
Suppose we have a class named asTrain it has two constructors, two methods, and a single attributeeach of which described as follows:
maxSpeed – an int value representing themaximum speed of the Train object.
Note: Trainspeed of modern Trains may be something like 250 km per hour, so avalue you could use for testing purposes is 250.
Adefault constructor:
Aconstructor that initializes the attribute mswhere ms is the maxSpeed.
Anoverloadedconstructor:
Aconstructor that takes ms as an argument, where msis the maxSpeed.
getMaxSpeed() – return the maxSpeed valueassociated withthe Train object.
setMaxSpeed(ms) – change the maxSpeed valueassociated with the Train object, where ms is the new value.
Explanation / Answer
int main()
{Train train,train2(250);
int max;
cout<<"Enter a new train speed for train: ";
cin>>max;
train.setMaxSpeed(max);
cout<<"Enter a new train speed for train2: ";
cin>>max;
train2.setMaxSpeed(max);
cout<<"new maxSpeed train:"<<train.getMaxSpeed()<<endl;
cout<<"new maxSpeed train2:"<<train2.getMaxSpeed()<<endl;
system("pause");
return 0;
}
Train::Train()
{
maxSpeed=100;
cout<<"default: maxSpeed: "<<maxSpeed<<endl;
}
Train::Train(int max)
{
maxSpeed=max;
cout<<"overload: maxSpeed: "<<maxSpeed<<endl;
}
int Train::getMaxSpeed()
{
return maxSpeed;
}
void Train::setMaxSpeed(int ms)
{
maxSpeed=ms;
}
