Hello Everyone , I have a Project at university to create term and polynomial class then calculate 2 derivatives I really need help for neccessery I have already started but I couldnt countinue , Hope to help !
Thanks ..
Note:The following attatchment contains project Details
Let's examine, step by step, what you have done so far:
I think I see your problem. You haven't actually tried to do it yourself. How about you show us what you have done.
Reverend Jim
Sorry , I think that you have misunderstand me , I just Posted the Assignment to show Project Details So you can help me as required and I really tried hard but I couldnt complete on some points because I am Just a beginner in C++ I dont want Full code I just want a simple explain to a specific points (Derivative , set/get , to String) so I can complete work
Thank you for trying to help me ..
You will find my code in the Attatchment
Minimal code, in a format that we have to jump through hoops to look at and it is uncommented and right justified. When I load it up every line starts with a semi-colon. Please post the code properly using the code insert tool, </>.
I cant understand how to deal with derivative and how to read the equation as a string
but the most confusing thing to me is data,, according to my information we define a pointer in the node class then use it in insert , delete and other functions as follow
pNew--> data = ..
but in the project we should identifiy coffiecnt and exponent How to deal with this?
#include <iostream>
using namespace std;
template <typename E>
class Polynomial {
private: Term <E>* head;
int count;
public: Polynomial() {
head = Null;
count = 0;
}
void InsertOrder(int coffiecnt, int exponent) {
Term <E>* pNew = new Term;
pNew->data = coffiecnt;
pNew->next = NULL;
if (head == NULL) {
head = pNew;
count++;
return;
}
else {
pNew->next = head;
head = pNew;
count++;
}
bool deletePoly(const T & coffiecnt , exponent) {
if (head == NULL) { cout << “ empty list “; return false; }
Term<T>* prev = NULL; Term <T>* cur = head;
while (cur && cur - > data !=coffiecnt) { prev = cur; cur = cur->next; }
if (cur == NULL) { cout << “not fount to remove “; return false; }
if (prev == NULL && cur != NULL) { removeFront(); return true; }
prev->next = cur->next;
delete cur;
count--;
return true;
string toString() {
}
int Derivaite() {
}
};
template <typename E>
class Term {
private:
E coffiecnt , exponent ;
Term <E>* next;
template <typename E>
friend class Polynomial;
};
int main() {
Polynomial p; //4x^5+2x^8
p.InsertOrder(4, 5);
string S;
cin >> S;
cout << p.toString();
Polynomial d = p.derivaite();
};Fine example of uncommented code
I especially liked
if (head == NULL) { cout << “ empty list “; return false; }
Term<T>* prev = NULL; Term <T>* cur = head;
while (cur && cur - > data !=coffiecnt) { prev = cur; cur = cur->next; }
if (cur == NULL) { cout << “not fount to remove “; return false; }
if (prev == NULL && cur != NULL) { removeFront(); return true; }
prev->next = cur->next;
delete cur;
count--;
return true;sorry sir , I couldnt understand !
I am just a beginner student not developer
this is what I understand from teacher and I am trying to find problems and solve it
because I really want to learn in the correct way not anything ...
I see Reverend Jim copy out a real doozie of a code passage which reminds me of an old saying:
When I wrote this only God and I understood this. Now, only God knows.
That code is a fine example where comments or more are mandatory since only the author may grasp what is going on.
I think that I couldnt arrive my idea as required ,
anyway Thanks for all of you
I will find another way to solve it
No details here but two suggestions:
Good luck!
