What is the purpose of the static storage class in C?

• To declare variables that are only accessible within the function

• To declare variables that are automatically initialized to 0

• To declare variables that are preserved throughout the program's execution.

• To declare variables that can be accessed by any function in the program

Explain the concept of dynamic storage class in C with an example.

• Dynamic storage class in C means that variables can change their data type during runtime.

• The concept of dynamic storage class in C refers to the use of external memory for storing variables.

• Dynamic storage class in C allows for the creation of variables with unlimited memory allocation.

• The concept of dynamic storage class in C allows for the allocation and deallocation of memory at runtime.

How is pointer arithmetic performed in C? Provide an example.

• By using bitwise XOR operation on the pointer and an integer value

• By multiplying the pointer with an integer value

• By adding or subtracting an integer value to/from a pointer

• By dividing the pointer by an integer value

Discuss the use of multi-dimensional arrays in C with an example.

• Multi-dimensional arrays in C are not supported by all compilers

• In C, multi-dimensional arrays can only have 2 dimensions

• An example of a multi-dimensional array in C is a 2D array to represent a matrix: int matrix[3][3];

• A multi-dimensional array in C is used to store only characters

Explain the concept of operator precedence in C and provide an example.

• Operator precedence in C has no impact on the evaluation of expressions.

• In C, operator precedence is only relevant for arithmetic operators and has no effect on logical or bitwise operators.

• In C, operator precedence is used to determine the order in which different operators are evaluated in an expression. For example, in the expression 5 + 3 * 2, the addition operator has higher precedence than the multiplication operator.

• In C, operator precedence is used to determine the order in which different operators are evaluated in an expression. For example, in the expression 5 + 3 * 2, the multiplication operator has higher precedence than the addition operator, so the expression is evaluated as 5 + (3 * 2) which equals 11.

What is a structure in C? How is it different from an array?

• A structure in C is a type of pointer that allows to store different types of data under a single name. It is different from an array as it can only store memory addresses and not actual data like arrays.

• A structure in C is a user-defined data type that allows to store different types of data under a single name. It is different from an array as it can store different types of data and is not limited to a single data type like arrays.

• A structure in C is a type of loop that allows to store different types of data under a single name. It is different from an array as it can only store integers and not other data types like arrays.

• A structure in C is a keyword used to define a function. It is different from an array as it can only store a single value and not multiple values like arrays.

What is the purpose of the register storage class in C?

• To declare global variables that can be accessed from any function

• To define variables that should be stored in a hard drive instead of RAM

• To define local variables that should be stored in a register instead of RAM for faster access.

• To specify variables that should be stored in the cache memory for faster retrieval

Explain the concept of row major order in multi-dimensional arrays.

• The elements of the last column are stored first

• The elements of the last row are stored first

• The elements of the first column are stored first

• The elements of the first row are stored first, followed by the elements of the second row, and so on.

What is a union in C? Provide an example to illustrate its usage.

• A union in C is a type of clothing item

• A union in C is a data structure that allows storing different data types in the same memory location. For example, consider a union named 'myUnion' that can hold an integer 'num' and a character array 'name'.

• A union in C is a type of mathematical operation

• A union in C is a type of labor organization

How does the dynamic storage class differ from the static storage class in C?

• Dynamic storage class allocates memory at runtime.

• Dynamic storage class does not allocate memory.

• Dynamic storage class allocates memory at compile time.

• Static storage class allocates memory at runtime.
