Set an integer to implement simple operations on integers

class IntSet
{
private:
    vector <int> Ints;
int element [100];
int n, seeknumber;
public:
IntSet ()
{
cout << "Enter the following integer:";
cin >> n;
        for (long i = 0; i <n; i ++)
{
cin >> element [i];
Ints.push_back (element [i]);
};
cout << endl << Ints [0];
};
Empty () {Ints.clear ();};
Isempty () {if (Ints.empty ()) cout << "The collection is empty!" << endl;};
bool Ismemberof ()
{
cout << "To determine if this number is inside the collection, please enter this number:";
cin >> seeknumber;
for (long j = 0; j <n; j ++)

if (Ints [j] == seeknumber) return true;

};
Add () {};
Sub () {};
Isequal () {};
Intersection () {};
Merge () {};
Print () {};
};
Is my program correct for the title? What else is missing, I hope everyone can give me pointers below! Thank you all here!

std :: string ToString ();
void Print (std :: ostream&);
Intersection is the meaning of intersection? How to understand the intersection of several integers?
Does Sub mean difference? The difference in multiple numbers can be dizzy.
Does Add insert or sum? Better change name

That's about it. The landlord should straighten out the idea and rewrite an interface is better

Good luck

Are Add and Sub add members and delete members?

You can add both string operations and mathematical statistics:
Number, sort, maximum, minimum, sum, mean, variance, set subtraction, set comparison ...

Good luck

no! The teacher said that my program is not perfect, but I don't know where it is! Is it different from the title?
Please help me discuss it.

achieve
operator + union
operator-poor
operator * intersection

This is an array! ? , For example, array a and array b, both arrays are recorded with array c, array a without array b is recorded with array A, array b without array a is recorded with array B

Ha ha, "element" is only used once in a function temporarily, just let it be a local variable of that function.

bool Ismemberof()
{
cout<<"To determine whether this number is inside the collection, please enter this number:";
cin>>seeknumber;
for (long j=0;j<n;j++)

if (Ints[j] == seeknumber) return true;
return false; // Pay attention to this sentence, should it warn when compiling?
};

In addition, it is best to write all the curly braces to make it clear.
