stu_test3_3.cpp: In static member function ‘static double Salesman::CalculateAveragePrice()’: stu_test3_3.cpp:21:12: error: ‘sumlesamount’ was not declared in this scope return sumlesamount; ^~~~~~~~~~~~ stu_test3_3.cpp:21:12: note: suggested alternative: ‘salesamount’ return sumlesamount; ^~~~~~~~~~~~ salesamount

这段代码中出现了一个错误。在Salesman类的静态成员函数CalculateAveragePrice中，返回值sumlesamount未被声明，因此编译器报错。我猜测可能是代码书写错误，应该为salesamount。因此，应该将代码修改为:

double Salesman::CalculateAveragePrice()  
{     
    return sum/salesamount;  
}

这样，该函数将会正确地计算并返回销售平均价。
