Write code to complete DoublePennies()'s base case. Sample output for below program:Number of pennies after 10 days: 1024

Note: These activities may test code with different test values. This activity will perform three tests, with startingPennies = 1 and userDays = 10, then with startingPennies = 1 and userDays = 40, then with startingPennies = 1 and userDays = 1.

#include <iostream>
using namespace std;

// Returns number of pennies if pennies are doubled numDays times
long long DoublePennies(long long numPennies, int numDays){
long long totalPennies;

/* Your solution goes here */

else {
totalPennies = DoublePennies((numPennies * 2), numDays - 1);
}

return totalPennies;
}

// Program computes pennies if you have 1 penny today,
// 2 pennies after one day, 4 after two days, and so on
int main() {
long long startingPennies;
int userDays;

startingPennies = 1;
userDays = 10;
cout << "Number of pennies after " << userDays << " days: "
<< DoublePennies(startingPennies, userDays) << endl;
return 0;
}

Please help me with this problem using c++.
