Discussion Forum : Arrays - Point Out Correct Statements (Q.No. 5)
5.
Which of the following statements are correct about an array?
| 1: | The array int num[26]; can store 26 elements. |
| 2: | The expression num[1] designates the very first element in the array. |
| 3: | It is necessary to initialize the array at the time of declaration. |
| 4: | The declaration num[SIZE] is allowed if SIZE is a macro. |
Answer: Option
Explanation:
1. The array int num[26]; can store 26 elements. This statement is true.
2. The expression num[1] designates the very first element in the array. This statement is false, because it designates the second element of the array.
3. It is necessary to initialize the array at the time of declaration. This statement is false.
4. The declaration num[SIZE] is allowed if SIZE is a macro. This statement is true, because the MACRO just replaces the symbol SIZE with given value.
Hence the statements '1' and '4' are correct statements.

SIZE is a macro but it is not sure that SIZE will expand to an integer, it could also be like this
#define SIZE 2.55
#define SIZE 2.55

num[26] store the 27 elements because it start with 0,1,2......26.
LIKE THAT only, then how is it true?

@Gopinath.Nan.
num[26] store the 26 elements because it start with 0,1,2......25.
num[26] store the 26 elements because it start with 0,1,2......25.

num[SIZE] is not a proper DECLARATION.
DECLARATION would be int num[SIZE];
DECLARATION would be int num[SIZE];
