Answer 2

Answer:

1.  The array int num[26]; can store 26 elements.

4. The declaration num[SIZE] is allowed if SIZE is a macro.

Explanation:

• int num[26] this statement states that name of the array is num which can store 26 integer values.
• The very first element of this array should be  denoted by num[0] as the array indexing starts at 0.
• It is not necessary to initialize the array at the time of declaration. One can initialize array using loop.
• when we define a macro then that macro name is replaced by the value of that macro . so, if SIZE is a macro and we declare num[SIZE] , then SIZE  will be replaced by its value.

#include<stdio.h>  

#define SIZE 5  

int main()  

{  

   int num[SIZE], i;  

 

   printf("Enter  a number\n", SIZE);  

   for(i = 0; i < N; i++)  

      { scanf("%d", &num[i]);  

 }

   printf("Array elements are:\n");  

   for(i = 0; i < SIZE; i++)  

       printf("%d\n", num[i]);  

     return 0;  

}
