                                             printf("Polynomial Evaluation\n\n");
                                             printf("Enter the Order of Polynomial (max. 10): ");
                                             scanf("%s",&n1);
                                             n=atoi(n1);
                                             if(n>10||n<1){
                                                           system("cls");
