The SQL command to create a table is:
-
MAKE TABLE
-
ALTER TABLE
-
DEFINE TABLE
-
CREATE TABLE
Correct Answer
A. CREATE TABLEExplanation
The correct answer is "CREATE TABLE" because it is the standard SQL command used to create a new table in a database. The "CREATE TABLE" statement is followed by the table name and the list of columns and their data types. This command allows users to define the structure of the table and specify the properties of each column, such as data type, length, and constraints.Rate this question:

Which of the following is not a type of constructor?
-
Copy constructor
-
Friend constructor
-
Default constructor
-
Parameterized constructor
Correct Answer
A. Friend constructorExplanation
A friend constructor is not a type of constructor in object-oriented programming. In C++, a friend function is a non-member function that has access to the private and protected members of a class. However, a friend constructor does not exist because constructors are always member functions of a class. Constructors are special member functions that are used to initialize objects of a class. The other options listed (copy constructor, default constructor, and parameterized constructor) are all valid types of constructors.Rate this question:

The term "push" and "pop" is related to the
-
Array
-
Lists
-
Stacks
-
All of above
Correct Answer
A. StacksExplanation
The terms "push" and "pop" are commonly used in the context of stacks. In a stack, the "push" operation adds an element to the top of the stack, while the "pop" operation removes the topmost element from the stack. Stacks follow the Last-In-First-Out (LIFO) principle, where the last element added is the first one to be removed. Arrays and lists can also be used to implement stacks, but not all arrays and lists are necessarily stacks. Therefore, the correct answer is "stacks."Rate this question:

To represent hierarchical relationship between elements, Which data structure is suitable?
-
Dequeue
-
Priority
-
Tree
-
Graph
Correct Answer
A. TreeExplanation
A tree data structure is suitable for representing hierarchical relationships between elements. In a tree, each element has a parent-child relationship, where each child node can have multiple child nodes of its own. This hierarchical structure allows for efficient organization and retrieval of data. Unlike a graph, which can have cycles and multiple connections between nodes, a tree enforces a strict hierarchical relationship, making it ideal for representing hierarchical data such as file systems, organization charts, or family trees.Rate this question:

__________ used to make a copy of one class object from another class object of the same class type.
-
Constructor
-
Copy constructor
-
Destructor
-
Default constructor
Correct Answer
A. Copy constructorExplanation
A copy constructor is used to create a new object by copying the values of another object of the same class type. It is typically used when we want to create a new object that is an exact copy of an existing object. The copy constructor takes an object as a parameter and initializes the new object with the same values as the parameter object. This allows us to create a new object with the same state as an existing object, without having to manually copy each individual member variable.Rate this question:

Running at the same constant rate, 6 identical machines can produce a total of 270 bottles per minute. At this rate, how many bottles could 10 such machines produce in 4 minutes?
-
648
-
1800
-
2700
-
10800
Correct Answer
A. 1800Explanation
If 6 identical machines can produce 270 bottles per minute, then each machine can produce 270/6 = 45 bottles per minute. Therefore, in 4 minutes, each machine can produce 45 * 4 = 180 bottles. Since there are 10 machines, the total number of bottles produced in 4 minutes by 10 machines is 180 * 10 = 1800.Rate this question:

The complexity of merge sort algorithm is
-
O(n)
-
O(log n)
-
O(n2)
-
O(n log n)
Correct Answer
A. O(n log n)Explanation
Merge sort is an efficient sorting algorithm that divides the input array into two halves, recursively sorts them, and then merges the sorted halves. The time complexity of merge sort is O(n log n), where n is the number of elements in the array. This is because the algorithm divides the array into halves logarithmically, and the merging process takes linear time. As a result, merge sort has a better time complexity compared to other sorting algorithms like bubble sort or insertion sort, which have time complexities of O(n2).Rate this question:

Correct Answer
A. Deletes the table structure along with the table data.Explanation
The DROP TABLE statement is used to delete a table from a database. It not only deletes the table structure but also removes all the data stored in that table. This means that all the records and information associated with the table will be permanently deleted. It is an SQL statement that is commonly used when a table is no longer needed or when there is a need to recreate the table with a different structure. The statement will execute successfully regardless of whether there are any referential integrity constraints in place.Rate this question:

-
Polymorphism, Encapsulation, and Inheritance
-
Encapsulation and Inheritance
-
Polymorphism and Encapsulation
-
Inheritance and Polymorphism
Correct Answer
A. Polymorphism, Encapsulation, and InheritanceExplanation
Polymorphism, encapsulation, and inheritance are used to produce a programming environment that supports the development of far more robust and scalable programs than the process-oriented model. Polymorphism allows objects to be treated as instances of their own class or as instances of their parent class, providing flexibility and reusability. Encapsulation ensures that data and methods are encapsulated within a class, protecting them from external interference and allowing for better organization and maintenance. Inheritance allows classes to inherit properties and methods from parent classes, promoting code reuse and modularity. Together, these three concepts enable the creation of more efficient and maintainable programs.Rate this question:

Correct Answer
A. Bottom-upExplanation
C++ follows the bottom-up approach. This means that it starts with smaller components and builds up to the larger ones. In C++, the program execution begins from the main function and then proceeds to call other functions or execute statements in a sequential manner. This approach allows for modular programming and better code organization, as smaller functions can be developed and tested independently before being integrated into the larger program. It also helps in optimizing performance by avoiding unnecessary computations and reducing memory usage.Rate this question:

One of the major drawback of B-Tree is the difficulty of traversing the keys sequentially.
-
True
-
False
-
None of the above
Correct Answer
A. TrueExplanation
The statement is true because in a B-Tree, the data is not stored in a sequential manner. Instead, it is organized in a hierarchical structure which makes it difficult to traverse the keys sequentially. In a B-Tree, each node can have multiple children, and the keys within a node are not necessarily in ascending or descending order. This makes it challenging to perform operations such as range queries or sequential access. Therefore, the statement accurately highlights one of the major drawbacks of B-Trees.Rate this question:

Which is a perfect example of runtime polymorphism?
-
Method overloading
-
Method overriding
-
Constructor overloading
-
None of the above
Correct Answer
A. Method overridingExplanation
Method overriding is a perfect example of runtime polymorphism. In method overriding, a subclass provides its own implementation of a method that is already present in its superclass. When a method is called on an object of the subclass, the JVM determines at runtime which version of the method to execute based on the actual type of the object. This allows for dynamic binding, where the appropriate method implementation is selected based on the object's type, enabling runtime polymorphism.Rate this question:
