4. Declare via existing array type
Question 3. Which of the following is a valid array declaration?
1. bearing: ARRAY [0.10] OF INTEGER;
2. bearing: ARRAY [0.10]: INTEGER;
3. bearing: INTEGER OF ARRAY [0.10];
4. bearing: ARRAY (0.10): INTEGER;
Question 4. What does the above program do?
```
  Var a: array [0.50] of real; 

  k: = 0; 

  for i: = 1 to 50 due 

  if a [i]> a [k] then k: = i; 
```
1. Find the smallest element in the array;
2. Find the largest element in the array;

```
  Var m: array [0.10] of integer; 
```
1. a [10];
2. a (10);
3. a [9];
4. a (9);
Question 6. Which of the following two-dimensional array declarations is wrong?
1. var m: array [1.10] of array [0.9] of integer;
2. var m: array [1.20,1.40] of real;
