Arrays

[Sreepadma]

I have declared an array and set values to it . for eg: arr[0]=1,arr[1]=12 etc.say for 5 elements. When i print the arr[0], i get 1 and when i print 0[arr], i get the value 1. same thing happens for arr[1] and the rest of the array elementns. What is happening here, could anyone please explain?

since the array operator leads to addition it is commutative
