What is the base address of a one-dimensional array in C?

• Address of the first element

• Address of the last element

• Address of the middle element

• Address of the array size

How do you access the third element of the array int arr[5] = {10, 20, 30, 40, 50}; using a pointer ptr initialized as int *ptr = arr;?

• ptr[3]

• *(arr + 3)

• *(ptr + 2)

• arr[3]

What is the output?

#include <stdio.h>

int main() {

int arr[3] = {100, 200, 300};

int ptr = arr; printf("%d", (ptr + 1));

return 0; }

• 100

• 200

• 300

• error

What is the correct way to declare an array of integer pointers in C?

• int *arr[5];
  
  
  

• int arr*[5];

• int (*arr)[5];

• int arr[5]*;

If int *arr[3] is an array of integer pointers and each pointer points to an integer, how do you access the integer pointed to by the second pointer?

• arr[1]

• *arr[1]

• &arr[1]

• **arr[1]
