Part 2:
Write a C program addressOfArray.c by inserting the code below in the main function.

 

1) Run the C program, attach a screenshot of the output in the answer sheet.

2) Attach the source code in the answer sheet

3) Then explain why the address after intvar is incremented by 4 bytes instead of 1 byte.

 

```c
// initialize an array of ints
int numbers[5] = {1,2,3,4,5};
int i = 0;

// print the address of the array variable
printf("numbers = %p\n", numbers);

// print addresses of each array index
do {
    printf("numbers[%u] = %p\n", i, (void *)(&numbers[i]));
    i++;
} while(i < 5);

// print the size of the array
printf("sizeof(numbers) = %lu\n", sizeof(numbers));
```

**Explanation:**
- The code initializes an integer array `numbers` with five elements.
- It then prints the memory address of the array `numbers`.
- The code uses a `do-while` loop to iterate through each index of the array, printing the memory address of each individual element.
- Finally, it prints the size of the whole array `numbers` in bytes using the `sizeof` function.
