Q1: Which of the following statements about arrays in C is not true:The first element in the array is at index 0The array name is a pointer constantAll of the elements in the array are of the same typeAn array must always have an associated buddy variable to indicate its sizeAn array can be of any type
Solution 1
The statement that is not true about arrays in C is: "An array must always have an associated buddy variable to indicate its size".
Explanation:
In C, the size of an array does not need to be indicated by a separate variable. The size of an array is determined at the time of its declaration and it cannot be changed. For example, if you declare an array as int arr[10];, the size of the array is 10. There is no need for a separate variable to indicate this. However, it is often useful to have a variable that keeps track of the number of elements currently being used in the array, especially in the case of arrays that are not fully utilized. But this is not a requirement.
Solution 2
The statement that is not true about arrays in C is: "An array must always have an associated buddy variable to indicate its size".
Explanation:
-
The first element in the array is at index 0: This is true. In C, array indexing starts from 0. So, the first element of an array is accessed by array[0].
-
The array name is a pointer constant: This is true. The array name points to the first element of the array and it cannot be reassigned.
-
All of the elements in the array are of the same type: This is true. In C, arrays are homogeneous data structures and can store multiple items of the same type.
-
An array must always have an associated buddy variable to indicate its size: This is false. In C, the size of an array does not need to be indicated by a separate variable. The size of an array is determined at the time of declaration and it cannot be changed.
-
An array can be of any type: This is true. In C, an array can be of any valid data type (int, float, char, etc.).
