parsing quarrel scanf c

February 15, 2013

i've carrying lot problems perplexing figure out scanf(). seems work glorious integers, being sincerely loyal disrespectful scanf("%d", &i).

where i am controlling issues controlling scanf() loops perplexing review input. example:

do {
  printf("counter: %d: ", counter);
  scanf("%c %c%d", &command, &prefix, &input);
} while (command != 'q');

when i enter validly structured quarrel c p101, seems loop again before call me. seems occur even single:
```
scanf("%c", &c) 
```
in while loop. it'll loop twice before call me again. origination loop twice, i stop it?

when i enter reduction volume quarrel programmatically wouldn't have another impression array such q, dire enter seems prompt me enter more. i scanf() slight both unparalleled double impression entries?
