Arrays challange in c++

Question

Can somone tell me why my code outputs the right values followed up by very large numbers?The challange is to output the array items discounted by the given input.
#include <iostream>
using namespace std;
int main() {
double items[]= {500, 12.4, 94, 45, 3, 81, 1000.9, 85, 90, 1, 35};
double dis;
cin>>dis;
double value;
for(int i=0;i<sizeof(items);i++)
{
value=items[i]-(items[i]*(dis/100));
cout<<value<<" ";
}
return 0;
}

Answer 1

sizeof (items) is outputting 88 ,total size occupied by each double in memory 8 bytes *11=88 bytes
If you are looking to get number of items it should be
sizeof(items)/ sizeof (items[0])

Answer 2

Thank you:)

Answer 3

Wouldn't it be better to replace sizeof(items) with items.length()
