# Problem clearing buffer, could use some help.

 P: 2 Hello, I am writing a program that will run once, and once done, ask the user if they would like to use it again. It has to work with any answer beginning with "y". I am having trouble with clearing the buffer when I answer "yes" or anything other than "y" itself. It works perfectly when "y" is entered, now I just need to somehow accept the other yes words and clear the buffer once the "y" has been consumed. code is as follows: Expand|Select|Wrap|Line Numbers #include    main ()   {          fputs("This program will calculate a table showing the voltage,"            "total resistance, and current for each increment of "            "resistance given the input from the user\n\n", stdout);          int ch, reply = 'y';      double initcur, endcur, inccur, voltage, current;            while ( reply == 'y' )          {          fputs("Enter voltage: ", stdout);          scanf("%lf", &voltage);          fputs("Enter initial resistance value: ", stdout);          scanf("%lf", &initcur);          fputs("Enter ending resistance value: ", stdout);          scanf("%lf", &endcur);          fputs("Enter incremental resistance value: ", stdout);          scanf("%lf", &inccur);            fputs("Table of induced currents\n\n", stdout);          fputs("     Voltage     Total Resistance     Current\n\n",          stdout);          fputs("     ----------------------------------------\n\n",          stdout);              for (initcur; initcur <= endcur ; initcur += inccur )          {            current = voltage / initcur ;              printf("        %.2f            %.4f        %.4f\n", voltage, initcur, current);          }          fputs("\nEnd of table.\n\n", stdout);          fputs("Would you like another computation? ", stdout);        while ((reply = getc(stdin)) !='\n');        scanf("%c", &reply);           }          return 0;   } I am supposed to be using the getc function, not fflush, so if you can tell where I might be going wrong, I would me most appreciative. :) Feb 13 '07 #1
