41. Simulate memcpy function Using Pointer Walk

You are given two memory buffers:

• A source array of n integers
• A destination array of the same size (pre-allocated, uninitialized)

Your task:

• Implement the function simulate_memcpy() to copy all elements from the source to destination
• ✅ You must use pointer arithmetic only
• ❌ Do not use array indexing (arr[i])

Constraints

• 1 ≤ n ≤ 100
• Data type: int
   

Example-1

Input: n = 5, source = [10, 20, 30, 40, 50]
Output: dest = 10 20 30 40 50

Example-2

Input: n = 3, source = [-5, 0, 5]
Output: dest = -5 0 5
