Assertions

	You will identify various assertions as being either always true, never true or sometimes true/sometimes false at various points in program execution.  The comments in the method below indicate the points of interest. 

public static int numOddDigits(int n) {
	int x = 0;
	<span class="assertionpoint">// Point A
	while (n != 0) {
		<span class="assertionpoint">// Point B
		if (n % 2 == 1) {
			x++;
			<span class="assertionpoint">// Point C
		}
		n = n / 10;
		<span class="assertionpoint">// Point D
	}
	<span class="assertionpoint">// Point E
	return x;
}

1) n == 0 

2) n % 2 == 1 

3) x == 0
