1 C

int enough(int cap, int on, int wait) {
  int res = on+wait-cap;
  return (res<0)? 0: res;
}

int enough(int cap, int on, int wait) {
  return (on + wait > cap) ? on + wait - cap : 0 ;
}

2 Python

def enough(cap, on, wait):
    return max(0, on + wait - cap)

def enough(cap, on, wait):
    res = on+wait-cap
    if res<0: return 0
    return res
