Question

Design a class named NumberClass that has a vector of any data type (use Class Template). You should create a parameterized constructor that accept the initialization value for the vector.

There should also be member functions to perform the following operations: - Print (cout) each element stored in the vector. -

#include <iostream>
#include <vector>
using namespace std;
//create code here

int main() {

NumberClass<int> myNum({99,34,12,44,77,2,37,4,54,68, 44, 102, 5, 42});
cout << "Print the elements in the vector" << endl;
myNum.printNumber();

Answer 1

#include <iostream>
#include <vector>
using namespace std;

template <class T>
class NumberClass {
private:
    vector<T> vec;
public:
    NumberClass(vector<T> vec) : vec(vec) {}
    void printNumber() {
        for (int i = 0; i < vec.size(); ++i) {
            cout << vec[i] << " ";
        }
        cout << endl;
    }
};

int main() {
    NumberClass<int> myNum({99, 34, 12, 44, 77, 2, 37, 4, 54, 68, 44, 102, 5, 42});
    cout << "Print the elements in the vector" << endl;
    myNum.printNumber();
    return 0;
}
