A functional programmer's question: What was this code ___intended to compute___?

int x = 5;
int y = 0;
while (x < 10) {
    print("Incrementing x");
    x = x + 1;
    y = y + 1;
}

// Hope: y holds the value 10 - x, for the original value of x.

int y = 10 - x;

def subtract(c, x):
  if (c == x) then 0 else 1 + subtract(c, x + 1)

subtract(c, x) = if (c == x) then 0 else 1 + (if (c == x + 1) then 0 else 1 + (if (c == x + 2) ))
