State whether each of the following is true or false. If the answer is false, explain why.a)A given array can store many different types of values. b)An array subscript should normally be of data type float. c)If there are fewer initializers in an initializer list than the number ofelements in the array,the remaining elements are initialized to the lastvalue in the initializer list.

a) False. In C/C++, an array can only store values of a single data type. For example, an array of integers can only store integers, an array of floats can only store floats, etc.
b) False. An array subscript should be of an integer data type, such as `int`. This is because the subscript is used to index the array, and array indices are always integer values.
c) False. If there are fewer initializers in an initializer list than the number of elements in the array, the remaining elements are initialized to 0 (for numeric types) or `nullptr` (for pointer types). For example, consider the following code:
```c++
int arr[5] = {1, 2}; // initialize first two elements to 1 and 2, respectively
```
In this case, `arr` will be initialized as `{1, 2, 0, 0, 0}`. The remaining elements are initialized to 0 because `int` is a numeric type. If `arr` was an array of pointers, the remaining elements would be initialized to `nullptr`.
