According to this page: "Double Declining Balance Method Depreciation Calculator"[^], you have

C++

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

int main()
{
        double asset_cost, salvage_val, deprec;
        double percentage, acc_deprec;
        const int YEARS = 10;


        cout<<"Asset cost: ";
        cin>>asset_cost;

        cout<<"Salvage value: ";
        cin>>salvage_val;

        percentage = 100.0 / YEARS;
        cout << "straight-line depreciation percentage " << percentage << endl;


        acc_deprec = 0.0;

        for(int y = 1; y <= 10 ; y++)
        {
                deprec = 2 * percentage / 100.0 * (asset_cost - acc_deprec);
                acc_deprec += deprec;
                cout<<deprec<<endl;
        }
        return 0;
}
