We want to calculate the total marks of each student of a class in Physics,Chemistry and
Mathematics and the average marks of the class. The number of students in the class are entered
by the user. Create a class named Marks with data members for roll number, name and marks.
Create three other classes inheriting the Marks class, namely Physics, Chemistry and Mathematics,
which are used to define marks in individual subject of each student. Roll number of each student
will be generated automatically.

bro do it on excel Microsoft office
Explanation:
here no answer getting is tha
Answer:
Here is the code in c++
Explanation:
#include <iostream>
#include <string>
using namespace std;
static int totalmo =0;
static int totalmm =0;
class marks
{
protected:
int roll_number;
string name;
public:
void setinfo(string namex, int roll)
{
name = namex;
// score = scorex;
roll_number = roll;
}
};
class physics : virtual public marks
{
protected:
int phy;
public:
void setphysics(int phyx)
{
phy = phyx;
totalmo +=phy;
totalmm +=1;
}
};
class chemistry : virtual public marks
{
protected:
int chem;
public:
void setchemistry(int chemx)
{
chem = chemx;
totalmo +=chem;
totalmm +=1;
}
};
class maths : virtual public marks
{
protected:
int math;
public:
void setmaths(int mathx)
{
math = mathx;
totalmo +=math;
totalmm +=1;
}
};
class student : public physics, public chemistry, public maths
{
public:

};
