Explanation / Answer

22. Its wrong. c) 4 is the right answer. This is because, value of DD is 5, and size of Arr is DD. So size of Arr is 5. But index of Array starts from 0 not 1. So all indexes are 0,1,2,3,4 and last index is 4.

23. c) for loop is correct. as using for loop we initialize indexes and using those indexes we traverse the array.

24. b) null character is correct. A C string terminates with '' character which is also called null character.

25. d) is wrong here. Correct option is c) first element of the array. This is because when we pass an entire array to the function eg arr, then it is equivalent to passing address of first element of array i.e. &arr[0] . So correct option is c
