Question

Which of the following statement(s) is/are correct w.r.t 'C' language?

(i) A part of the array can be passed to the function instead of the whole array.

(ii) Numeric array elements cannot be assigned initial values if the array is defined as a pointer variable.

1. Neither (i) nor (ii)
2. (i) and (ii) both 
3. (ii) only 
4. (i) only

Answer 1

Correct Answer - Option 2 : (i) and (ii) both 

The correct answer is option 2.

Option 1: A part of the array can be passed to the function instead of the whole array.

True, C language does not allow to pass an entire array as an argument to a function. However, You can pass a pointer to an array by specifying the array's name without an index.

Option 2: Numeric array elements cannot be assigned initial values ​​if the array is defined as a pointer variable.

True,  If the array is defined as a pointer variable An array is a pointer, and you can store that pointer into any pointer variable of the correct type.

For example,

int A[10];

int* p = A;

p[0] = 0; makes variable p point to the first member of array A.

Setting p[0] = 0 is equivalent to setting A[0] = 0, since pointers p and A are the same. When numeric array elements cannot be assigned initial values it just assign the address of the array and pointer variable like int* p = A.

Hence the correct answer is both (i) and (ii).
