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;

    // Point A
    while (n != 0) {
        // Point B
        if (n % 2 == 1) {
            // Point C

        n = n / 10;
        // Point D

    // Point E
    return x;

Fill in each box of the the table below with ALWAYS, NEVER or SOMETIMES.

n == 0 n % 2 == 1 x == 0
Point A
Point B
Point C
