Passing a Vector to Constructor in C++

This is a simple C++ program to pass a vector to a constructor.

Algorithm

Begin
   Declare a class named as vector.
      Declare vec of vector type.
      Declare a constructor of vector class.
         Pass a vector object v as a parameter to the constructor.
         Initialize vec = v.
         Declare a function show() to display the values of vector.
            for (int i = 0; i < vec.size(); i++)
               print the all values of variable i.
   Declare v of vector type.
      Initialize some values into v in array pattern.
   Declare ob as an object against the vector class.
      Pass values of v vector via ob vector object to class vector.
   Call show() function using vector object to show the all values of
   vector v.
End.

Example Code

 Live Demo

#include <iostream>
#include <vector>
using namespace std;
class Vector {
   vector<int> vec;
   public:
      Vector(vector<int> v) {
         vec = v;
}
void show() {
   for (int i = 0; i < vec.size(); i++)
      cout << vec[i] << " ";
   }
};
int main() {
   vector<int> v = {7,6,5,4};
   Vector ob(v);
   ob.show();
   return 0;
}

Output

7 6 5 4
