◾出力ステートメントを使用して、入力データと計算結果を表示します。小数点以下 2 桁にフォーマットされた 10 進数値を表示します。 ここが私が困っているところです！この特定のプロジェクトのために他のすべてが行われているため、たとえば、支払い率に 4.4444 を使用し、時間数に 10 を使用すると、通常の支払いが 44.44 であることが出力されます。44.444ではありません！

std::setprecisionとstd::fixedでうまくいくはずです。

次のようなものが必要なようです。

 std::cout << std::fixed << std::setprecision(2);
