C++ Program to Find Transpose of a Matrix
A matrix is a rectangular array of numbers arranged in rows and columns. To find the transpose of a matrix, we arrange the rows of the original matrix as columns in a new matrix. Similarly, the columns can also be arranged as rows. An example of the transpose of a matrix is as follows: Finding Transpose of a Matrix To find the transpose of a matrix in C++, we use multidimensional arrays to store matrix values in rows and columns. Then, we swap the rows and columns to get the transpose. Below are the steps we followed: ...
Read MoreCan we write any code after throw statement in Java?
No, we can not place any code after throw statement, it leads to compile time error. The compiler will show this error as unreachable statement. In Java, the throw statement immediately terminates the current flow of execution, therefore, the code immediate to a throw statement will not be executed. The control is then transferred to the next catch block or the caller method. The throw Keyword in Java The throw keyword is used to throw an exception manually. Whenever it is required to stop the execution of the functionality based on the user-defined logical error condition, we will use this ...
Read MoreWhen are static objects destroyed in C++?
C++ Static Object A static object is declared with the static keyword. The static objects are initialized only once and stored in the static storage area. The static objects are only destroyed when the program terminates i.e. they live until program termination. In this article, we will understand static object, their types, and their examples. Syntax of Static Object The syntax for declaring a static object is as follows: Animal cat; //object declaration static Animal dog; //static object declaration Types of Static Objects The static objects can be of two types, which are mentioned below: ...
Read MoreC++ Program to Implement B+ Tree
A B+ tree is an m-tree that consists of a root, internal nodes, and leaves. The root may be a leaf or a node with two or more children. A B+ tree is an advanced data structure that extends the B-tree by adding a linked list of leaf nodes. A B+ tree can be a B-tree where each node contains only keys (not key-value pairs). What is B+ Tree? A B+ tree is a self-balancing tree data structure that maintains sorted data and allows for efficient insertion, deletion, and search operations. It differs from a B-tree in the following ways: ...
Read MoreC++ Program to Implement Stack Using Two Queues
Queue The queue is a linear data structure that follows the First-In-First-Out (FIFO) operation. Where insertions are done at one end (rear) and deletions are done from another end (front). The first element that is entered is deleted first. Following are the stack operations: EnQueue (int data): Insertion at rear end int DeQueue(): Deletion from front end Stack The stack is also a linear data structure that follows the Last-In-First-Out (LIFO) operation. Where the element will be added and removed from the top. Following are the stack operations: ...
Read MoreWhy is a C++ pure virtual function initialized by 0?
In C++, the pure virtual function is initialized with = 0 to indicate that it must be overridden by the derived class and has no implementation in the base class. A pure virtual function is a virtual function in C++ declared in a base class that has no implementation within that class. Why Initialize by 0? The following are the reasons for initializing by 0: 1. Mark The Function as "Pure Virtual" The = 0 syntax tells the compiler that the function must be overridden by any derived class. The base ...
Read MoreDefault virtual behavior in C++ vs Java
The default behaviour of virtual functions in C++ and Java is significantly different, especially in terms of the handling of method overriding and polymorphism. Default Virtual Behavior in C++ C++ methods are non-virtual by default. To enable dynamic polymorphism, the virtual keyword must be explicitly used in the base class when defining a method. If virtual is not given, the method call is handled at compile time using the object of static type. Example In this example, we implement the default behaviour of the virtual function in C++: #include using namespace std; class Base { public: void nonVirtualMethod() { cout
Read MoreTemplate Metaprogramming in C++
C++ Template metaprogramming (TMP)Template metaprogramming (TMP) is a metaprogramming technique in which a template is used by the compiler to generate temporary source code, which is merged by the compiler with the rest of the source code and then compiled. The best use of template metaprogramming is in C++. The use of templates can be thought of as compile-time polymorphism. The use of templates as a metaprogramming requires two distinct operations: A template must be defined and a defined template must be instantiated. Syntax The syntax of template metaprogramming is not defined by code, but we can explain it and ...
Read MoreC++ Program to implement Slicker Algorithm that avoids Triangulation to find Area of a Polygon
In this article, we implement a C++ program to find the area of a polygon using a slicker algorithm that avoids Triangulation to find the area of a polygon. What is Slicker Algorithm The Silcker algorithm is a method for calculating the area of a polygon by performing a series of calculations based on the polygon's vertices. It is an efficient alternative to triangulation, especially for polygons with many sides. How Silcker Algorithm Works? Since slicker is a method used to compute the area of a polygon without triangulation. Instead of breaking the polygon into triangles, it directly computes the ...
Read MorePrint a character n times without using loop, recursion or goto in C++
In this article, we will see how to print a character n times without using loops and recursion in C++. Input/Output Scenario Let's see following input output scenario − Input : n = 10, c = 'i' Output : iiiiiiiiii Input : n = 5, character = 'j' Output : jjjjj Using String Constructor Here, using the string constructor in C++ to print a character n times: It allows initialization of a string with multiple copies of a specific character by passing the number of times and the character itself as arguments. Example In this C++ example, we ...
