Take a[5], it will store address of a[0] in a. when it will access the array only by a it will increment a or it will take a+1,a+2,a+3 and so on.
When array is passed to any function we will pass as
add(a);
In definition it will take it in pointer and access whole array
Hence at the time of passing array it will pass only base address i.e. address of first element of array. |
