Assuming int is of 4bytes, what is the size of int arr[15];?
Answer: D
Correct answer: 60
The size of an array is the number of elements times the size of one element:
\[ 15 \times 4 = 60 \text{ bytes} \]So sizeof(arr) gives 60. Note that this holds only where the array itself is in scope - passed to a function it decays to a pointer, and sizeof then yields the pointer’s size.
