Question

State whether each of the following is true or false. If false, explain why:

a.Referring to an array element outside the array bounds is a syntax error.

b.When initializing an array at its declaration, it is a syntax error to provide less initializers than the number of array elements.

c.A character array can be initialized using a string literal.

d.An individual array element that is passed to a function and modified in that function will contain the modified value when the called function completes execution.

e.When a not-initialized pointer is dereferenced, it initializes itself to NULL

f.The fields of a struct can be of different types, but the array elements cannot.

g.structs and arrays are always passed to functions by reference

Answer 1

Answers are

a) Answer is False

Referring to an array element outside the array bounds is a logical and execution error

b.) Answer is False

When initializing an array at its declaration, and we provide less initializers than the number of array elements. then it is not a syntax error instead remaining elements will already initialize to 0

c )  Answer is True

Yes we can initialize a character array using a string literal

d) Answer is False

We can pass values to function in two types

1. Pass by value: In this method the modification don't reflect in original array
2. Pass By Reference : in this method the modification made in function will reflect in original array

So it is false as we can also pass the individual element by value so modification done will not effect in array after function ends

e) Answer is False

Non -Initialize pointer point to some random location in memory it is not initialized to null by default

f) Answer is True

Yes Struct can have several data types elements but array contain elements with same data type

g) Answer is False

Structs can be passed by value and reference but array are passed by reference only .

So these are the correct answers for each part
