hard📝 Application Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Identify size of one integer
On a 32-bit system,inttypically uses 4 bytes.Step 2: Calculate total memory for 1000 integers
Total memory = number of elements x size of each element = 1000 x 4 = 4000 bytes.Final Answer:
4000 bytes -> Option CQuick Check:
1000 x 4 = 4000 bytes [OK]
Quick Trick: Multiply count by size of int (4 bytes) [OK]
Common Mistakes:
- Using size 2 bytes for int
- Multiplying by 8 bytes (double size)
- Confusing bits with bytes
