类的继承和函数重载出现问题（商品入库出库类的程序）no overloaded function takes 5 arguments

不知道怎么修改求大神给看看。

void delete_m()这个函数应该怎么写，求教啊。

另外如果在主函数里想要输入商品名，类型，数量，价格等等，然后用数组输出，应该怎么写主函数，求教。

初学者提的问题有点多，请见谅。

问题在于你的第二个构造函数，有五个参数，但是基类没有类似的构造函数

[AndyStevens]

void Material::registermaterials_m(char *n, string t, int a, int d, float p):Material()
{
    this->name_m = n;
    this->type_m = t;
    this->amount_m = a;
    this->date_m = d;
    this->price_m = p;
    //this->total_price_m = tp;
 
}

不太懂，求指点如何改?

无视2楼， 不要用.运算符调用registermaterials_m ， 用->去调用

不太懂，不好意思，请问怎么调用。
