C++ Program to Emulate N Dice Roller
Emulating an n dice roller refers to rolling n number of dice simultaneously. In each roll, all the dice will return a different value from 1 to 6. In this article, we are having 'n' number of dices, our task is to emulate rolling n dices simultaneously. The approaches are mentioned below: Using Loop with rand() Function Using Recursion Using Loop with rand() Function In this approach, we have used the rand() function to generate a random value of dice in each roll. The srand() function with time() is ...
Read MoreC++ Program to Check the Connectivity of Undirected Graph Using BFS
The Breadth-First Search (BFS) algorithm is a graph traversal algorithm that starts at the tree root and explores all nodes at the present depth before moving to the nodes at the next level. In this article, we will discuss how to check the connectivity of a graph using BFS traversal algorithm. Understanding Connectivity of a Graph A graph is said to be connected if there is a path between every pair of vertices. To check connectivity of a graph, we will try to traverse all nodes using any traversal algorithm. After completing the traversal, if there is any ...
Read MoreWhat is the importance of a Cursor class in Java?
In this article, we will learn about the importance of the Cursor class in Java. Under the Swing toolkit, the Cursor class provides an improved user experience by providing graphical(visual) feedback. What is a Cursor class? A Cursor is a subclass of the Object class, and it can be defined as point or indicator on the screen. A Cursor is used to select the input from the system that the user operates with the mouse. The important methods of Cursor class are getDefaultCursor(), getName(), getPredefinedCursor(), getSystemCustomCursor(), and getType(). Syntax The following is the syntax: Cursor cursor = new Cursor(Type_of_Cursor); Different ...
Read MoreWhat should main() return in C and C++?
In C/C++, the main() function is used in the beginning of every program. This returns the program execution status in the operating system. Syntax Following is the syntax of the main() function using C/C++: int main(void); int main(int argc, char *argv[]); Example Below, the C/C++ example shows the usage of the main() return value. C C++ #include int main() { printf("Hello, C World!"); return 0; } Key Points of C Return 0: This is standard for successful execution Non-zero: It indicates error Implicit return: C99 allows omitting return #include int main() { std::cout
Read MoreDifference between Tree Set and Hash Set in Java
In Java, HashSet and TreeSet both belong to the collection framework. HashSet is the implementation of the Set interface, whereas TreeSet implements a sorted set. TreeSet is backed by TreeMap while HashSet is backed by a HashMap. Difference Table The following are the key differences between HashSet and TreeSet : Sr. No. Key ...
Read MoreJava program to compare two sets
The given task is to write Java programs that compare two sets and check if they are equal or not. Here, Set is an interface of the Java Collection Framework that extends the Collection interface and stores unique elements. Set depicts the features of a mathematical set. Hence, it allows all those operations that we can perform on a mathematical set, such as union, comparison, intersection, etc. Since Set is an interface, we can't use its functionalities directly. For this purpose, we need a TreeSet class that implements the Set Interface and can access its methods. How to Compare Two Sets in ...
Read MoreWhat are the differences between JTextField and JTextArea in Java?
The main difference between JTextField and JTextArea in Java is that a JTextField allows entering a single line of text in a GUI application while the JTextArea allows entering multiple lines of text in a GUI application. JTextField The following are the key characteristics of JTextField in Java: A JTextFeld is one of the most important components that allow the user to an input text value in a single line format. A JTextField will generate an ActionListener interface when we trying to enter some input inside it. The JTextComponent is a superclass of JTextField that provides a common set ...
Read MoreConvert a C++ String to Upper Case
In C++, converting a string into uppercase means changing all the characters into uppercase. This is a common requirement in many applications, such as formatting output, standard data input, and case sensitivity. Following is the table that shows the conversion of string to uppercase: String Case Characters Uppercase Characters ...
Read MoreC++ Program to Convert Octal Number to Binary Number
In a computer system, the binary number is expressed in the binary numeral system while the octal number is in the octal numeral system. The binary number is in base 2 while the octal number is in base 8. Here, we provide the tabular data to understand binary numbers and their corresponding octal numbers as follows: Octal Number ...
Read MoreUnderstanding cin.clear() and cin.ignore() in C++
When we attempt to work with user input in C++, unwanted behavior may be caused by errors or leftover characters in the input buffer. So, in that case cin.clear() and cin.ignore() are functions that can help in dealing with this kind of problem. cin.clear() cin.ignore() cin.clear and cin.ignore() cin.clear() The cin.clear() resets the error flags on the cin stream and is used when an input operation fails (e.g., entering a non-numeric value for an integer variable). Without clearing the error flags, further input operations will not work. ...
