MCA-101 QUIZ

What is the purpose of using array in programming?

• To store multiple values in a single variable

• To display a message on the screen

• To create a loop in the program

• To perform complex mathematical calculations

Explain the concept of stack in data structure.

• A stack is a linear data structure that follows the Last In First Out (LIFO) principle.

• A stack is a data structure used for sorting elements in ascending order.

• A stack is a non-linear data structure that can be accessed randomly.

• A stack is a linear data structure that follows the First In First Out (FIFO) principle.

How does a queue differ from a stack?

• A queue follows the Last In First Out (LIFO) principle.

• A queue can only be implemented using arrays.

• A queue follows the First In First Out (FIFO) principle.

• A queue can only have elements of the same data type.

What are pointers and how are they used in programming?

• Pointers are variables that store the value of another variable

• Pointers are used to store text data in programming

• Pointers are only used in high-level programming languages

• Pointers are variables that store the memory address of another variable. They are used to manipulate memory and create dynamic data structures in programming.

Discuss the importance of file handling in programming.

• File handling is only necessary for printing documents

• File handling is only used for playing audio and video files

• File handling allows manipulation of files, such as reading from or writing to them, which is essential for tasks like data storage, retrieval, and processing.

• File handling is not important in programming

What is the syntax for creating an array in C?

• dataType arrayName[arraySize];

• arrayName[arraySize] dataType;

• arrayName = new arraySize[dataType];

• arrayName = arraySize(dataType);

What are the applications of queues in real-life scenarios?

• Playing video games

• Handling customer service calls

• Cooking a meal

• Sending emails

How are pointers different from normal variables?

• Pointers are not used in computer programming

• Pointers store memory addresses

• Pointers store values directly

• Pointers are only used for text-based data

How are arrays implemented in memory?

• Arrays are implemented in memory as contiguous blocks of memory, with each element occupying a specific memory location.

• Arrays are implemented in memory as a single memory location for all elements

• Arrays are implemented in memory as non-contiguous blocks of memory

• Arrays are implemented in memory as a linked list of memory locations

What are the different file handling operations in C?

• Printing

• Opening, reading, writing, closing, seeking

• Copying

• Deleting
