if statement woes

[Brian Berry]

I can't wrap my head around how to write the following if statement. Some help would be greatly appriciated


"if a counter variable has decremented by one then allow"

i

cou0--
if(cou0 ???){
  //cou0 has changed
}

How does cou0 get decremented? It seems to me you either need another variable to contain the old value of cou0, or a flag that is set whenever cou0 is decremented by 1 (but it would need to be reset when it's not decremented, which might be difficult to define).

cou0--
if(cou0 ???){
  //cou0 has changed
}

Seems to me that the only really reasonable way to do that would be to set a temp var before whatever code decrements it:

ctemp = cou0
// whatever code determines the decrement
cou0--
if (cou0 == ctemp-1) {
  // cou0 has changed
}

I don't see any other approach that would be viable.

Perfect Thanks!
