Having trouble initiating an array in a structure

Question

class CRA_Account {
    int tax[4];
    double refund[4];
    int SIN;
 public:
    CRA_Account();
 }

 CRA_Account::CRA_Account() {
     SIN = 0;
     tax[4] = { 0 };
     refund[4] = { 0 };
 }

When I create a object in main it'll set the SIN to 0 but won't do the same to the arrays. Can someone help why?

Use the initializer list to construct attributes. What you're doing here is an assignment and that doesn't work with arrays. — Caninonos

Here ideone.com/CQBvR8 the part starting with the colon before the constructor body is called a member initializer list — Caninonos

1) use the initializer list. 2) there's std::fill. 3) why not a std::array? — Jesper Juhl

tax[4] = { 0 }; is wrong at many levels.. One way to initlizie your class:

CRA_Account::CRA_Account():
   tax{0,0,0,0},
   refund{0,0,0,0},
   SIN{0}{
}

Try to have a look at std::array
