Consider the following array declaration: int arr[4] = {2, 4, 5}; What will be the output of the following 'C' statement? printf("%d", 3[arr]);

Consider the following array declaration: int arr[4] = {2, 4, 5}; What will be the output of the following 'C' statement? printf("%d", 3[arr]); Correct Answer 0

The correct answer is option 1.

Concept:

Array:

 An array is defined as the collection of similar types of data items stored at contiguous memory locations. Arrays are the derived data type in C programming language which can store the primitive type of data such as int, char, double, float, etc. It also has the capability to store the collection of derived data types, such as pointers, structure, etc. The array is the simplest data structure where each data element can be randomly accessed by using its index number.

Explanation:

The given 

int arr = {2, 4, 5};

Here By default, when we create an array of something in C all entries will have their default value. For primitive types like int, long, float the default value is zero.

Hence the correct answer is 0.

A student wrote two context-free grammars G1 and G2 for generating a single C-like array declaration. The dimension of the array is at least one. For example, int a[10] [3] ; The grammars use D as the start symbol, and use six terminal symbols int; id[ ] num Grammar G1 Grammar G2 D → int L; D → int L; L → id[E L → idE E → num] E → E[num] E → num][E E → [num]   Which of the grammars correctly generate the declaration mentioned above?
