023. Write a program to accept roll number ,and marks for three subjects, print total marks and average, also print grade by considering following conditions

1. #include<stdio.h>
2. #include<conio.h>
3. main()
4. {
5. int RollNumber,m1,m2,m3,total;
6. float avg;
7. clrscr();
8. printf("Enter Roll Number : ");
9. scanf("%d",&RollNumber);
10. printf("Enter marks for three subjects : ");
11. scanf("%d%d%d",&m1,&m2,&m3);
12. total=m1+m2+m3;
13. avg=total/3.0;
14. printf("\nTotal is....... %d",total);
15. printf("\nAverage is..... %5.2f %",avg);
16. if(avg>=60)
17. printf("\nGrade : A");
18. else if((avg>=50)&&(avg<60))
19. printf("\nGrade : B");
20. else if((avg>=40)&&(avg<50))
21. printf("\nGrade : C");
22. else
23. printf("\nGrade : F");
24. getch();
25. }
