What is printed by: char s[] = "hello"; printf("%zu", sizeof(s));?

The correct answer is B: 6. sizeof(s) includes the null terminator '\0'. "hello" has 5 characters + 1 null terminator = 6 bytes. If s was a pointer, sizeof would give pointer size.

In C, which operator has the highest precedence?

What is the time complexity of a binary search algorithm on a sorted array?

The correct answer is B: O(log n). Binary search divides the search space in half with each iteration, resulting in logarithmic time complexity O(log n).

Which of the following statements about pointers is correct?

The correct answer is B: A pointer stores the memory address of a variable. A pointer is a variable that stores the memory address of another variable. You can access the value at that address using the dereference operator (*), and pointers can point to any data type.

Consider: int *ptr; int arr[] = {1,2,3}; ptr = arr; What is ptr[1]?

The correct answer is B: 2. When ptr points to the array arr, ptr[1] is equivalent to *(ptr+1), which accesses the second element of the array, which is 2.
