Assuming int is of 4bytes, what is the size of int arr[15];?Select one:a.15b.19c.11d.60Clear my choice

1. Break Down the Problem

To find the size of the array int arr[15], we need to compute the total number of bytes it occupies in memory.

2. Relevant Concepts

• The size of one int is given as 4 bytes.
• The size of an array can be calculated using the formula:
  $\text{Size of array} = \text{Number of elements} \times \text{Size of each element}$

3. Analysis and Detail

• Number of elements in the array: 15
• Size of each element (int): 4 bytes

Now, applying the formula: $\text{Size of arr[15]} = 15 \times 4 \text{ bytes}$

4. Verify and Summarize

Calculating the size: $\text{Size of arr[15]} = 60 \text{ bytes}$ So, the calculated size is indeed 60 bytes.

Final Answer

The size of int arr[15]; is 60 bytes. The correct option is d. 60.
