I have a question for beginners Using class statements, we are distributing capabilities as a random function and making characters and monsters to make a game, but I have a question because of the c2659 error

Header file.

pragma once
class character
{
private:
    int m_HP;
    int m_MP;
    int m_ATK;
    int m_Def;
public:
    character();

    ~character();
    void setHP(int m_HP);
    int hp()
    {
        return m_HP;
    }
    void setMP(int m_MP);
    int mp()
    {
        return m_MP;
    }
    void setatk(int m_ATK);
    int atk()
    {
        return m_ATK;
    }
    void setdef(int m_Def);
    int def()
    {
        return m_Def;
    }
};
It's a cpp

include"character.h"
include"COMMON.h"
character::character()
{

}
character::~character()
{

}
void character::setHP(int hp)
{
    m_HP = hp;
}
void character::setMP(int mp)
{
    m_MP = mp;
}
void character::setatk(int atk)
{
    m_ATK = atk;
}
void character::setdef(int def)
{
    m_Def = def;
}
This is the main function
void main()
{
        character *player = new character[a];
    character *monster = new character[a];
void stat(character *p, int a, int b)
{

    The function p->atk = rand() %a + b;//=' was used as the left operand
    The function p->def = land() %a;//=' was used as the left operand
    The function p->hp = land() %a + b;//=' was used as the left operand
    p->mp = land() %b;//"=" function used as left operand "
}
}

There is a c2659 error over there, but I am asking you because I cannot find a solution even if I search and read a book I think it'll be hard to see if I upload it all, so I'm going to skip it If you need it, I'll upload more.

I think you uploaded the main function wrong.

void stat(character *p, int a, int b)
{
    The function p->atk = rand() %a + b;//=' was used as the left operand
    The function p->def = land() %a;//=' was used as the left operand
    The function p->hp = land() %a + b;//=' was used as the left operand
    p->mp = land() %b;//"=" function used as left operand "
}

void main()
{
    character *player = new character;
    character *monster = new character;

    int a = 0, b = 1;
    stat(player, a, b);
    stat(monster, a, b);
    //...
}

I think it's the same as above and I'll answer it.

If you look at p->atk = rand() %a + b; here, you are substituting integers in the member function. The function cannot be substituted because it is not a variable.

You need to change the expression to substitute for the member variable, but because the member variable is private, you need to change it to use the set** member function you created.

void stat(character *p, int a, int b)
{
    p->setatk(land() %a + b);//=' function used as left operand
    p->setdef(land() %a);//=' function used as left operand
    p->setHP(land() %a + b);//=' function used as left operand
    p->setMP(land() %b);//"=" function used as left operand "
}
