Question

我不知道怎么或为什么和谷歌不是真的有用更好,,,但是谁能告诉为什么剂量这个错误弹出以及如何解决？我尝试了所有我能想到的......我没有想法。

错误部分：

return 0;
}


int main()
{
//Main function of the program. no pre/ post condition.
Array M;
constr(M);
Array B;
constr(B);
dummyData(Array M);

printMenu();
return 0;
}

数组标题：

struct Array{
    int days;
    int exp;
    int **M;
};

void constr(Array &);
void destruc(Array &);
void add(int, int, Array &);

控制器添加功能：

void add(int cant,int tip, Array M){
//Adds to current day the amount to a specific type
    currDay();
    M.M[currentDay][tip] += cant;
}

Answer 1

您不会调用这样的函数：

add(int cant,int tip, Array M);

您无需指定数据类型：

add(cant,tip, M);

此处：dummyData(Array M); - ＆gt; dummyData(M);

仅在声明中指定数据类型，但在调用函数时不指定。

Answer 2

    case 1:add(int cant,int tip, Array M);

调用add时，不指定实际参数的类型。

编译日志有没有人知道如何弹出这个错误？
