'float'を 'float *'に変換することはできません。

Question

これを計算して表示するには問題があります。割り当てのために私は外部機能を持たなければなりません。私はこれを守っている：

私はかなり一般的なコーディングに新しいので、どんな助けも素晴らしいだろう。最初の部分は、メインファイルの外部と2番目の部分です。

Answer 1

エラーは自明です。それらを渡すときは、calcNet()機能がfloat*ポインタの代わりに

あなたfedtax、statetax、およびssitaxパラメータはすでに、で始まる - であるようにちょうどそれらを渡すためにfloat*のポインタであるが、それらを逆参照しません期待されているfloat値を渡しています〜calcNet()。これに

*totNet = calcNet(gross,*fedtax,*statetax,*ssitax,defr); 

：

*totNet = calcNet(gross,fedtax,statetax,ssitax,defr);
