I want to add a faction float diff()

#include

using namespace std;

struct node

{

int info;

node *next;

};

class sll

{

private:

node *head;

public:

sll(){head=NULL;}

void AddNode (int);

void Traverse();

int Sum();

};

void sll::AddNode (int val)

{

node *newNode= new node;

newNode->info=val;

newNode->next=head;

head=newNode;

}

void sll::Traverse()

{

if (head==NULL)

cout

for (node * curr=head;curr; curr=curr->next)

coutinfo

}

int sll::Sum ()

{

int sum=0;

for (node * curr=head;curr; curr=curr->next)

sum+=curr->info;

return sum;

}

int main()

{

sll s;

int inf, ch;

while(1)

{

cout

cin>>ch;

switch(ch)

{

case 1:

cout

cin>>inf;

s.AddNode(inf);

break;

case 2:cout

s.Traverse();

break;

case 3:

cout

break;

default: exit(0);

} // end of switch

} // end of while loop

return 0;

}

Create a program to store a list of integer numbers dynamically through a singly linked list, your program should contain the following functions: 1- AddNode (int): Adds a new node at the end of the list. 2- Traverse0: Prints the values stored in the list. 3- float diffo: Returns the difference between the average of positive numbers and the average of negative numbers. Note: - Just attach the code for the third function in your answer. - You should also attach a screenshot of the program output
