Assume the other functions are implemented correctly. The Train class's function: remove First Car of Type. This function removes the first car from the list that has a string name that matches the provided string. Do not use any other Train class Your solution for the above functions should go in this box, which should be considered part of train.

// constructor
Train()
{
head = NULL;
}

//Destructor
~Train(void)
{
struct Node* temp;
while (head != NULL)
{
temp = head->next;
delete head;
head= temp;
}
}

2B.

void removeFirstCarofType(string str)
{
struct Node* temp=head,*q;
while(strcmp(temp->name,str)!=0)
{
q=temp;
temp=temp->next;
}
if(strcmp(temp->name,str)==0)
{
q->next=temp->next;
delete temp;
}
