as part of my assignment were having out programs tested like mad, I know one of the tests is to see if they can overload scanf by pressing and leaving their fingers on a button for 2 mins and watching it crash.

Im pretty sure the way around it involves the "get or fget" functions, but I have no clue as to how/where to use it, as any resources on the net are far to complex for me to understand.

heres a sample clip from my program, theres about 20-25 input sections in total.

CODE
do
       {                                
                system("cls");                                  
                printf("\n\nPlease select the spot frequency in Hz : ");
                scanf("%s",bufferfreq);
                freq = (float)atof(bufferfreq);    
       }
                while (freq <= 0 || freq >= 1000000001);


Thank you

I had a problem with that in one of the books I was reading.... All I did was set a loop and adjusted the buffer overload. Told it when the loop completes just to go back to the begining of the loop and start over with what you had before the loop started... I think I explained that right....
