                fseek(fp1, -1, 1);
                n_o_b_l++;
            }
        }
        if (ch  ==  ';')
        {
            if ((ch = fgetc(fp1))  ==  '\n')

        {
            if ((ch = fgetc(fp1))  ==  '/')
            {
                n_o_c_l++;
            }
        }
    }
    printf("Total no of lines: %d\n", line_count);
    printf("Total no of comment line: %d\n", n_o_c_l);
    printf("Total no of blank lines: %d\n", n_o_b_l);
    printf("Total no of non blank lines: %d\n", line_count-n_o_b_l);
