Question

我无法解决这个问题，需要显示一个netpay。对于作业，我必须有一个外部功能。我保留这个：

calcTax.cpp：在函数'void calculateTaxes（float，float，float *，float *，float *，float *）'中：

calcTax.cpp：61：56：错误：无法将参数'2'的'float'转换为'float *'为'float calcNet（float，float *，float *，float *，float）'

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

我对编码很新，所以任何帮助都会很棒。第一部分是主文件中的外部和第二部分。

Answer 1

错误不言自明。您正在传递float值，而calcNet()函数需要float*指针

您的fedtax，statetax和ssitax参数已经是float*指针，因此请按原样传递它们，在传递时不要取消引用它们他们到calcNet()。 IOW，改变这个：

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

到此：

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

参数'2'无法将'float'转换为'float *'
