Continues with the next loop iteration.

# =============================================================================
# 繼續 — Continues with the next loop iteration.
# =============================================================================
#
# What this teaches:
#   • Loop control — `繼續` skips the rest of the current iteration and proceeds to the next.
#   • Nested loops — In nested loops, `繼續` applies to the innermost loop.
#
# Common mistakes:
#   • Using `繼續` outside a loop — `繼續` is only valid inside `當` or `遍歷` (SEM031).

# Continue (繼續) in loops
#
# 繼續   -- skip to next iteration of innermost loop
#
# GRAMMAR:
#   continueStmt :← '繼續'
#
# EXPECTED OUTPUT:
#   Odd integers 1–9, then nested pairs skipping interior == 3.

main {
    # Skip even numbers
    var int i ← 0
    while i ≺ 10 {
        i ← i + 1
        if i % 2 ≡ 0 {
            continue
        }
        print i
    }

    # Continue in nested loop
    var int exterior ← 0
    while exterior ≺ 3 {
        var int interior ← 0
        while interior ≺ 5 {
            interior ← interior + 1
            if interior ≡ 3 {
                continue
            }
            print "exterior←§, interior←§"(exterior, interior)
        }
        exterior ← exterior + 1
    }
