W.A.P to find out the total & average of student. Using structure within structure

#include<iostream.h>

#include<conio.h>

            struct student {

                        char nm[20];

                        int total;

                        float avg;

            struct marks {

                        int m1,m2,m3;

            };

            struct marks m;

            };

            void main()

             {

            struct  student s;

              clrscr();

              cout<<"Enter the Name of the Student.....     ";

              cin>>s.nm;

              cout<<"Enter the marks of Three Subjects....  ";

              cin>>s.m.m1>>s.m.m2>>s.m.m3;

              s.total = s.m.m1+s.m.m2+s.m.m3;

              s.avg=s.total/3.0;

             

              cout<<"\n\n\n\n\n\n\n\t\t===============================================";

              cout<<"\n\n\t\t The Name of the student is "<<s.nm;

              cout<<"\n\t\t The Average of the student is "<<s.avg;

              cout<<"\n\t\t===============================================";

              getch();

             }

OUTPUT:

Enter the Name of the Student.....     R GABA

Enter the marks of Three Subjects....  90

80
