Question

Programming Problem: define a C++ Bucket class with the following methods: Bucket() constructor that takes two parameters, a string name and an int parameter, the bucket capacity print) takes no paramers. Prints the bucket name, capacity and contents. Returns void. fill) that takes no parameters, fills the bucket to capacity. Returns void. empty ) that takes no parameters, empties the bucket. Returns void pourinto) takes one parameter, a reference to a Bucket object, returns an int that is the number of gallons transferred. This method pours the calling object Bucket into the parameter object bucket. As much of the first bucket as will fin into the remaining capacity of the parameter bucket is transferred. The class will have thee private data members, name, capacity and contents. Name is a string, and is the name of the bucket. Capacity is the size of the bucket, and contents is the amount of water the bucket currently contains.

Hi there,

Following is the answer if you still have any queries,feel free to ask in the comments box.

Code:

#include <iostream>

using namespace std;

class Bucket

{public:

string name;

int capacity;

int contents;

Bucket(string name,int capacity)//parameterised constructor

{

this->name=name;

this->capacity=capacity;

this->contents=0;

}

void print()//print the details

{

cout<<"Bucket name : "<<name<<endl;

cout<<"Bucket capacity : "<<capacity<<"units"<<endl;

cout<<"Bucket contents : "<<contents<<"units"<<endl;

}

void fill()//fiill the bucket

{

contents=capacity;

}

void empty()//empty thr bucket

{

contents=0;

}

int pour_into(Bucket *b)//pour into another

{

if(this->contents+b->contents<=b->capacity)

{

b->contents+=this->contents;

int temp=this->contents;

empty();

return temp;

}

else if(b->capacity-b->contents<=contents)

{

int needed=(b->capacity-b->contents);

if(contents>=needed)

{

b->contents+=needed;

contents-=needed;

return needed;

}

else if (contents<needed)

{ int temp=contents;

b->contents+=contents;

empty();

return temp;

}

}

return 0;

}

};

int main()

{

Bucket a("A",3);

Bucket b("B",5);

int c=1;

while(c==1)

{

a.print();

b.print();

cout<<endl;

int ch;

cout<<"0-Exit\n";

cout<<"1-Fill Bucket A\n";

cout<<"2-Empty Bucket A\n";

cout<<"3-Pour A into B\n";

cout<<"4-Fill Bucket B\n";

cout<<"5-Empty Bucket B\n";

cout<<"6-Pour B into A\n";

cout<<"Enter your choice\n";

cin>>c;

switch(c)

{

case 0:

break;

case 1:

a.fill();

break;

case 2:

a.empty();

break;

case 3:

cout<<a.pour_into(&b)<<" units transferred from A to B\n";

break;

case 4:

b.fill();

break;

case 5:

b.empty();

break;

case 6:

cout<<b.pour_into(&a)<<" units transferred from B to A\n";

break;

}

cout<<"Do you wish to continue(1 for yes 0 for no)\n";

cin>>c;

}

return 0;

}

Output:
