Array string pointers in c++

Question

How could I make the array "a" of this code dynamic with pointers?
Array "b" will be the same size as array "a".
abc --> aabbcc
dcab --> ddccaabb

Answer 1

You can use std::array for that:

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

int main() {
array<string, 3> a = {"a","b","c"};
array<string, a.size()> b;

for (int i=0; i < 3; i++){
b[i] = a[i]+a[i];

}

for (int i=0; i < 3; i++){
cout << b[i] << endl;
}
return 0;
}
