scanf but not complete

[Unregistered]

I want to use scanf to get up to 10 chars. Each char will go into a different variable. Here is my code.

scanf("%c%c%c%c%c%c%c%c%c%c", &c1, &c2, &c3, &c4, &c5, &c6, &c7, &c8, &c9, &c10);

The problem: I do not care if the user does not enter 10 chars. I want to allow the user to enter any number of chars up to a maximum of 10. But if the user enters say 5 chars and press enter, the program will wait for another 5 chars. How do I stop it from waiting? Thanks

someone please help!
I can explain it better if you need.... I have been trying it and I think maybe I have to use getchar() instead of scanf but I do not know what I would do if I used getchar() and I wanted each char in a different variable. Can someone please help me with this? Thanks

I take it your not up on char arrays (strings) yet.

You are right, is it possible to do what I want with what we have learnt so far (very very basic stuff)? If so, even if it is not the prefered way to do it, can you please show me how. I have tried and tried with scanf and getchar() but I am unable to do it. Thanks

One possible solution to your problem is to use a while loop and use an array instead of 10 different variables...like...


char ch[10];
int i;

i=0;
while(i<10)
{
ch[i]=getche();
if(ch[i]=='\n')
break;
else
i++;
}

Try it Out...

Thanks vsriharsha but I have a small problem, we have not learned arrays yet I was wondering if it is possible to do it without arrays? Or am I being asked to do something that we have not learned the background for yet? I know arrays is probably the prefered method, but can it be done without them? Thanks for your help

char ch, c1, c2, c3, c4 ect ect;
int i = 1;

while(i < 11)
{
   ch = getchar();
   if(ch = '\r') break;

   switch(i)
   {
          case 1: c1 = ch;break;
          case 2: c2 = ch;break;
          case 3: c3 = ch; break;
          ect. ect
          case 10:c10 = ch;break;
    }
    i++;
}

scanf("%c%c%c%c%c%c%c%c%c%c", &c1, &c2, &c3, &c4, &c5, &c6, &c7, &c8, &c9, &c10);

Yeah, you would really want to avoide something repetitive like this when you program. For one, it's very prone to error and makes debugging that much harder, and it's hard to read. The idea of the loop was good (if you really don't want to use strings).
