Newbie: ipairs() for tables with non integer keys

["Ganesh Gunasegaran" <ganesh.gunasegaran@...>]

Hi,

Does ipairs() work only with integer keys? if so why?

student = {}
student.name = "Test"
student.age = 25

for i,v in ipairs(student) do -- A
    print(i,"=>",v)
end

test_arr = {4,5,6}
for i,v in ipairs(test_arr) do -- B
    print(i,"=>",v)
end

#########################
---------- Run ----------
1    =>    4
2    =>    5
3    =>    6

Output completed (0 sec consumed) - Normal Termination

I expected that the for loop at A to print something like
"name"  =>    "Test"
"age"    =>    25


Cheers,
