Question

我的目标是将数组传递给函数，但出现以下错误：

error: cannot convert ‘float’ to ‘float*’ for argument ‘9’ to ‘void calc_fun(float*, float*, float*, float*, float*, float*, float*, float*, float*, float*, int)’
     calc_fun(rate, hrs_worked, gross, overtime, state_tax,fed_tax, uni_fee, net, total_gross, avg_gross, SIZE);

我真的不明白为什么，因为我认为它遵循与void input_fun(...)相同的步骤，似乎工作得很好。

IDE显示的其他错误，可能会有所帮助。（不在调试器中，我使用CLion）：

calc_fun(rate, hrs_worked, gross, overtime, state_tax, fed_tax, uni_fee, net, total_gross, avg_gross, SIZE);` -> no matching functions for call to "calc_fun" 


void calc_fun(float rate[], float hrs[], float gross[], float overt[], float st_tx[], float fed_tx[], float uni_fee[], float net[], float tgross, float agross, const int S)` -> is never used, I don't understand this one as it's being used in `int main`.

任何帮助将不胜感激，谢谢。

void calc_fun(float[], float[], float[], float[], float[], float[], float[], float[], float[], float[], const int);
// scroll right                                                                                ^^^^^^^

您已将此参数声明为指针。

float /* snip */
      total_gross = 0,

您已将total_gross声明为float。它不是数组，也不是指针。

calc_fun(rate, hrs_worked, gross, overtime, state_tax,fed_tax, uni_fee, net, total_gross, avg_gross, SIZE);
// scroll right                                                              ^^^^^^^^^^^

您将total_gross作为声明为指针的参数传递。类型不匹配。

错误：无法将“ float”转换为“ float *”作为参数
