Question

Q5: Write a code to read two integer arrays of size n and count the number of zeros in both of them. Q3: Write a code to read a 4 x 4 matrix of integers and find the summation of the even numbers in the matrix.

Answer 1

The code provided counts the number of zeros in two integer arrays by iterating through each element and checking if it is equal to zero. The final count is returned as the result.

Step-by-step explanation:

To count the number of zeros in both integer arrays, we can follow these steps:

1. Initialize a counter variable to zero.
2. Iterate through each element of the first array.
3. Check if the current element is equal to zero.
4. If it is, increment the counter by one.
5. Repeat steps 2-4 for the second array.
6. The final value of the counter will be the total number of zeros in both arrays.

Here is an example code snippet in Python:

def count_zeros(arr1, arr2):

count = 0

for num in arr1:

if num == 0:

count += 1

for num in arr2:

if num == 0:

count += 1

return count

# Example usage:

array1 = [1, 0, 2, 0, 3]

array2 = [0, 4, 0, 5, 0]

zeros_count = count_zeros(array1, array2)

print('Total number of zeros:', zeros_count)
