the code is follows :
#include<iostream.h>
#include<conio.h>
#include<iomanip.h>
class student
{
protected :
int rollno;
public:
void get_roll()
{
cout<<"\nEnter Roll No";
cin>>rollno;
}
void put_roll()
{
cout<<"\nRoll No - "<<rollno;
}
};
class test : public student
{
protected:
int m1,m2;
public:
void get_mark()
{
cout<<"\nEnter marks of two subjects";
cin>>m1>>m2;
}
void put_mark()
{
cout<<"\nm1 = "<<m1;
cout<<"\nm2 = "<<m2;
}
};
class sport
{
protected:
int score;
public:
void get_score()
{
cout<<"\nEnter score";
cin>>score;
}
void put_score()
{
cout<<"\nscore = "<<score;
}
};
class result : public test , public sport
{
private :
int total;
public:
void procdata()
{
total = m1 + m2 + score;
}
void put_total()
{
cout<<"\nTotal = "<<total;
}
};
void main()
{
clrscr();
result x;
x.get_roll();
x.get_mark();
x.get_score();
x.procdata();
x.put_roll();
x.put_mark();
x.put_score();
x.put_total();
}
Error :
After i enter the roll no, marks of two subjects and score , the computers gets back to code window , and doesnot execute the complete program , i am not getting why exactly is it happening , but do help !
Well , Syed , it did not work for me , the compler or Turbo C++ 3.0 , which i use still leaps out before completeley executing the program , do help , if u can , and thanx for the answer !

I have debugged your code in Dev C++, and commented on errors.
#include<iostream> // iostream.h includes just one file... i am including folder
#include<conio.h>
//#include<iomanip.h> // No need to use it
using namespace std; // For using standard console functions
class student
{
protected :
int rollno;
public:
void get_roll()
{
cout<<"\nEnter Roll No";
cin>>rollno;
}
void put_roll()
{
cout<<"\nRoll No - "<<rollno;
}
};
class test : public student
{
protected:
int m1,m2;
public:
void get_mark()
{
cout<<"\nEnter marks of two subjects";
cin>>m1>>m2;
}
void put_mark()
{
cout<<"\nm1 = "<<m1;
cout<<"\nm2 = "<<m2;
}
};
class sport
{
protected:
int score;
public:
void get_score()
{
cout<<"\nEnter score";
cin>>score;
}
void put_score()
{
cout<<"\nscore = "<<score;
}
};
class result : public test , public sport
{
private :
int total;
public:
void procdata()
{
total = m1 + m2 + score;
}
void put_total()
{
cout<<"\nTotal = "<<total;
}
};
int main() // main() has to be of return type int.
{
system("cls"); //clrscr(); // Consider using native commands for optimizing code.
result x;
x.get_roll();
x.get_mark();
x.get_score();
x.procdata();
x.put_roll();
x.put_mark();
x.put_score();
x.put_total();
system("pause"); // You need to pause the screen to see the code...!
return(0); // You must return integer in main()...preferably 0.
}
If you are beginner, please use Dev C++. Its easy to use.
