JShell is a REPL (Read-Eval-Print-Loop) interactive tool introduced in Java 9 that takes input, evaluates it, and returns output to a user.java.util.LocalDate class provides a number of methods to retrieve Date information: Day/Month/Year and related attributes Date meta-information: Classification-related information such as whether a leap year, etc. LocalDate class is immutable, and we can use different methods provided to add and subtract days, months, and years. Each of these returns a new instance of LocalDate.In the below two code snippets, we can able to print different operations using LocalDate class.Snippet-1jshell> import java.time.*; jshell> LocalDate today = LocalDate.now() today ==> 2020-04-22 jshell> today.getYear() $3 ==> ...

A Publisher is a provider of an unbounded number of sequenced elements publishing them according to demand received from its Subscribers. Publisher interface is responsible for publishing elements of type T and provides a subscribe() method for subscribers to connect to it.public interface Publisher { public void subscribe(Subscriber
In this article, we will be discussing the raw string literal in C++, its meaning, and examples.There are escape characters in C++ like “” or “\t”. When we try to print the escape characters, it will not display on the output. To show the escape characters on the output screen we use a raw string literal by using R”(String with escape characters)”. After using R in the front of the string the escape character will be displayed on the output.ExampleLet’s understand this with the help of an example Live Demo#include using namespace std; int main(){ string str = "tutorialspoint" ...

In this article, we will be discussing the working, syntax, and examples of modulus functions in C++.What is modulus function C++?modulus function object class in C++, which is defined in header file. modulus function is a binary function object class used to get the result of the modulus operation of the two arguments. This function works the same as the operator ‘% ‘.Syntax of modulus functionTemplate struct modulus : binary_function { T operator() (const T& a, const T& b) const {return a%b; } };Template parametersThe function accepts the following parameter(s) −T − This is the type of the ...

In this article, we will be discussing the working, syntax, and examples of ilogb() function in C++.What is ilogb()?ilogb() function is an inbuilt function in C++ STL, which is defined in iostream> using namespace std; int main(){ int output, var = 2; output = ilogb(var); cout
In this article, we will be discussing the working, syntax, and examples of imag() function in C++.What is imag()?imag() function is an inbuilt function in C++ STL, which is defined in header file. imag() is used to find the imaginary part of the complex number.A complex number is a number which is made by the combination of a real number and an imaginary number. Real numbers are any number except the infinity and imaginary numbers.Imaginary numbers are those numbers whose square is a negative number. The function returns the imaginary part, the imaginary part which is the factor by which ... Read More
In this article, we will be discussing the working, syntax, and examples of remainder() function in C++.What is remainder()?remainder() function is an inbuilt function in C++ STL, which is defined in header file. remainder() is used to find the remainder of the parameters.This function takes two arguments, one for the numerator and second for the and computes its remainder and returns a floating-point which is rounded to the nearest.This function computes −remainder = numerator – roundquot * denominator;In which “remainder” is the resulting numerator being the first argument and denominator is the second argument and roundquot is the rounded ...

In this article, we will be discussing the working, syntax, and examples of rand() and srand() function in C++ STL.What is rand()?rand() function is an inbuilt function in C++ STL, which is defined in header file. rand() is used to generate a series of random numbers. We use this function when we want to generate a random number in our code.Like we are making a game of ludo in C++ and we have to generate any random number between 1 and 6 so we can use rand() to generate a random number.The random number is generated by using an ...

In this article, we will be discussing the working, syntax, and examples of ratio_not_equal template in C++ STL.What is ratio_not_equal template?ratio_not_equal template is inbuilt in C++ STL, which is defined in header file. ratio_not_equal is used to compare the two ratios that are unequal. This template accepts two parameters and check whether the given ratios should not be equal. Like we have two ratios, 1/2 and 3/9 which are not equal so it stands true for the given template. This function returns true when the two ratios are unequal.So, when we want to check for the inequality of the ... Read More
