Lua 常用遍历

b = {}
for i=,  do
    b[i] = i
end

-- method one
for i, v in pairs(b) do
    print (i, v)
end

-- method two
for i, v in ipairs(b) do
    print (i, v)
end

-- method three
for i = , #b  do
    print (i, b[i])
end

-- method four
for i = , table.maxn(b) do
    print (i, b[i])
end

lua常用的四种遍历，前两种是泛型遍历，后两种是数值的遍历.
