Let's break down the code step by step:

import numpy as np

a = np.array([1, 2, 1, 5, 8])
b = np.array([0, 1, 5, 4, 2])

c = a + b  # Element-wise addition of a and b
c = c * a  # Element-wise multiplication of c and a

print(c[2])  # Print the third element of array c

Step-by-Step Explanation:

1. a and b arrays:

   • a = np.array([1, 2, 1, 5, 8])
   • b = np.array([0, 1, 5, 4, 2])

2. c = a + b:

   • Element-wise addition of a and b:

   c = [1+0, 2+1, 1+5, 5+4, 8+2]
   c = [1, 3, 6, 9, 10]
   

3. c = c * a:

   • Element-wise multiplication of c and a:

   c = [1*1, 3*2, 6*1, 9*5, 10*8]
   c = [1, 6, 6, 45, 80]
   

4. print(c[2]):

   • The third element (index 2) of the array c is 6.

Output:

(A) 6
