Why the size of int a =[5] is 5 instead 6 , isn't the first term is 0?

Answer 1

The last element of an array with size [5] has the index 4.

Answer 2

The size of the array is 5 and according to formula "index=array size-1" so Index is 4

Answer 3

The index is like this 0,1,2,3,4
That means size is 5 not 6

Answer 4

When sending or retrieving the length of an array, you're dealing in a one-based system. Whereas locating an element at a specified index in an array is zero-based. Thus, we can deduce that `int a[5];` is dealing with length, which is a one-based system.
