実数値の配列の最大値を返す関数（2回め）

この質問でアドバイスいただいたように、

int maxDoubleArray(int a[],int size) {...}

の箇所を

double maxDoubleArray(double a[],int size) {...}

と直したのですが、以下のようなエラーが出てしまいました。

format ‘%lf’ expects argument of type ‘double *’, but argument 2 has
type ‘int *’ [-Wformat=]    scanf("%lf", &a[i]);
          ~~^   ~~~~~

このようなエラーには、どう対処したら良いですか。
