What are the basic components of C tokens?

• Comments, Annotations, Macros, Exceptions

• Data Types, Classes, Modules, Interfaces

• Keywords, Identifiers, Constants, String Literals, Operators, Punctuation Symbols

• Variables, Functions, Loops, Arrays

Which of the following is not a type of operator in C?

• function pointer

What is the purpose of control statements in C?

• The purpose of control statements in C is to manage the flow of execution in a program.

• To create functions in C

• To define variables in C

• To handle memory allocation in C

How do structures help in organizing data in C?

• Structures help in organizing data by grouping related variables of different types into a single unit, improving data management and readability.

• Structures are used to create functions in C.

• Structures only store data of the same type.

• Structures cannot contain arrays or pointers.

What is the syntax to declare an array in C?

• type arrayName[];

• type arrayName[arraySize];

• arrayName[type] arraySize;

• arrayName{type, arraySize};

How do pointers enhance memory management in C?

• Pointers only manage static memory allocation.

• Pointers enhance memory management in C by enabling dynamic memory allocation, efficient data structure implementation, and direct memory manipulation.

• Pointers are used solely for string manipulation.

• Pointers do not allow for efficient data structure implementation.

What is the difference between a structure and a union in C?

• Structures and unions are identical in functionality and usage in C.

• A structure is used for memory management, while a union is used for data processing.

• A structure can hold multiple values simultaneously, while a union can hold only one value at a time.

• A structure can only hold one value at a time, while a union can hold multiple values simultaneously.

Which operator is used for pointer dereferencing in C?

• &

• ->

• %

• *

What are the different types of control statements in C?

• Data type definitions

• Function statements

• Variable declarations

• Selection statements, Iteration statements, Jump statements

How can you initialize an array in C?

• int arr[3] = {1, 2};

• int arr[] = {1, 2, 3};

• int arr = {1, 2, 3};

• int arr[3] = new int[3];
