Write it, run it, read the output

This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Declare the local array marks with the values 12, 7, 19, and 3. Print each index, its value, and its byte offset from the start of the array, then print the array's total byte count using sizeof.

index 0: value 12, offset 0
index 1: value 7, offset 4
index 2: value 19, offset 8
index 3: value 3, offset 12
total bytes: 16
