Answer 1

alagammai uma ,
Because you used
a[n] = 0
Instead of
n = 0

In range-based for loops
(int n : a)
every iteration n gets assigned to the corresponding value in the array a.

So there is no need for [] here, as n will be equal to the next value in the array every iteration...

Answer 2

alagammai uma

for(int n : a)

This is called enhanced for loop and here n will be each value of an array a

But when you do a[n] then here n will work as index

For the array {1, 2, 3, 4, 1}

n = 1
a[n] = 0 means a[1] = 0

Now array will be {1, 0, 3, 4, 1}

Now on next iteration n = 0 so a[0] = 0

Now array will be {0, 0, 3, 4, 1}

Again on next iteration n = 3 so a[3] = 0

Now array will be {0, 0, 3, 0, 1}
