Error invalid conversion from 'const char*' to 'char*' - object

Question

I Expect to get the name which I sent to the "class stud" which has a class variable CHAR name
The issue appears specifically at this line this->name->set_name_send(OBJ.name->get_name());
and I get this error " -- invalid conversion from 'const char*' to 'char*' -- "
Any suggestions?
enter image description here
If I make the function set_name as a const and delete the pointers in the destructor code runs but return value is garbage and it has to be 0
Maybe the class *name doesn't have to be pointer ?
All pointer and in OOP
#include <iostream>
#include <cstdlib>
#include <cstring>
#include <iomanip>
using namespace std;
class CHAR
{
char *name;
public:
CHAR(char *mes = "\0") {(this)->name = new char[100]; strcpy((this)->name,mes);}
CHAR(const CHAR&OBJ) { (this)->name = new char[100]; strcpy((this)->name,OBJ.name); }
~CHAR(){cout<<"CHAR Destructor!"<<endl; delete name;}
void set_name(char *mes){(this)->name = new char[100]; strcpy((this)->name,mes);}
const char* get_name() const {return (this)->name;}
};
class stud
{
CHAR *name;
public:
stud(char *mes)
{
this->name->set_name(mes);
}
stud( stud&OBJ)
{
this->name->set_name(OBJ.name->get_name()); //!!!!!!!!!!!!!!! issue HERE!!
}
~stud(){cout<<"Destructor!"<<endl;}
const char* get_name() const {return this->name->get_name();}
};
int main()
{
stud S("John");
stud A(S);
cout<<"Name: "<<A.get_name()<<endl;
}
