In C++, array indexing always starts from 0.
That means:
The first element of an array is accessed using index 0
The second element uses index 1, and so on
Example:
int a[3] = {10, 20, 30};
Index-wise access:
a[0] = 10
a[1] = 20
a[2] = 30
Correct Answer: B) 0
Description:
C++ uses zero-based indexing for arrays.
