                                int a[25],i;

                                printf(“Enter the marks of 25 students:\n”);

                                for(i=1;i<=25;i++)

                                {

                                                scanf(“%d”,&a[i]);

                                }

                                for(i=1;i<=25;i++)

                                {

                                                if(a[i]>50)

                                                                printf(“%d marks are greater than 50%\n”);

                                }

                                getch();
