The declaration of the JellyBeanJar class is given below. Instances of the JellyBeanJar class represent bean jars of varying capacity. The member variable maxJellyBeans represents the capacity of the jar. The member variable Jellybeans represents the current number of jelly beans in the jar, which must be less than or equal to maxJellyBeans. The class provides functions to add jelly beans, remove jelly beans, and get the number of jelly beans that are currently in the jelly bean jar. The functions to add and remove jelly beans return a boolean value that indicates whether the operation succeeded or failed. When one of these functions fails, the number of jelly beans in the jar will not have been changed. For example, if a jelly bean jar has a capacity of 10 jelly beans and there are 9 jelly beans currently in the jar, then addJellyBeans(2) will return false and the number of jelly beans in the jar will remain at 9.
class JellyBeanJar {
public:
JellyBeanJar(int maxB, int b);
int getJellyBeans() const;
bool addJellyBeans(int b);
bool removeJellyBeans(int b);
private:
int maxJellyBeans;
int Jellybeans;
};
Please write the implementation of the constructor and the addJellyBeans function.
