size of vector and array not same why?

Question

so here a example code

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

int main() {
int myArray[3]{ 5, 10, 15 };

vector<int> myVector(begin(myArray), end(myArray));

for (int x : myVector)
cout << x << " ";
// 5 10 15
for(int i : myArray)
cout<<i<<" ";
cout<<"\n"<<sizeof(myVector);
cout<<"\n"<<sizeof(myArray);
}

//output
//5 10 15 5 10 15
//24
//12

Answer 1

to determine size or length of vector, use vector.size();
