Read Moreexpm1() in C++
The function expm1() is used to calculate the exponential raised to the power of any number minus one. It returns the value of (exponential raised to the power of a) - 1.Here is the mathematical expression of expm1(),expm1(a) = (e^a) - 1Here is the syntax of expm1() in C++ language,float expm1(variable_name);Here,variable_name − Any name given to the variable whose value is calculated.Here is an example of expm1() in C++ language,Example#include #include using namespace std; int main() { int x = 10; float y = 8.28; cout
Read MoreC# DateTime Max Value
To set the max value for a Date, use the DateTime property MaxValue.DateTime max = DateTime.MaxValue;Now, display the value of max to get the maximum value of a date as shown below.Exampleusing System; using System.Linq; public class Demo { public static void Main() { DateTime max = DateTime.MaxValue; Console.WriteLine(max); } }Output12/31/9999 11:59:59 PM

Use the BufferHeight gets or sets the height of the buffer area.Use the property like this −Console.BufferHeightLet us see the complete example.Exampleusing System; class Demo { static void Main() { Console.WriteLine("Buffer height (rows) = "+Console.BufferHeight); } }OutputBuffer height (rows) = 0
Read MoreWhat is the scope of a private member variable of a class in C#?
Only functions of the same class can access its private members. Private access specifier allows a class to hide its member variables and member functions from other functions and objects.Exampleusing System; namespace RectangleApplication { class Rectangle { //member variables private double length; private double width; public void Acceptdetails() { length = 10; width = 14; } public double GetArea() { return length * width; } ...
Read MorePassing and Returning Objects in Java
As we know it is core concept that in Java there is always pass by value and not by pass by reference.So in this post we will focus on that how this concept get validated in case of passing primitive and passing reference to a method.In case when a primitive type is passed to a method as argument then the value assigned to this primitive is get passed to the method and that value becomes local to that method, which means that any change to that value by the method would not change the value of primitive that you have ...
Read MoreConvert.ToChar Method in C#
The Convert.ToChar method is used to convert a specified value to a Unicode integer.We have declared an sbyte variable.sbyte byteVal = 200;Now, use the Convert.ToChar() method to convert the sbyte value to a Unicode integer.charVal = Convert.ToChar(b);Let us see another example.Exampleusing System; public class Demo { public static void Main() { sbyte[] byteVal = { 92, 111, 115 }; char charVal; foreach (sbyte b in byteVal) { charVal = Convert.ToChar(b); Console.WriteLine("{0} converted to '{1}'", b, charVal); } } }Output92 converted to '' 111 converted to 'o' 115 converted to 's'

Read MoreC# Program to return a collection with repeated elements
To return a collection with repeated elements in C#, use Enumerable.Repeat method.It is part of System.Linq namespace.Let’s say you need to repeat a number twice, for that set the number and the frequency of repetition.Enumerable.Repeat(50, 2);Now assign it to a variable and display it.Exampleusing System; using System.Linq; class Demo { static void Main() { // repeating element 50, two times var num = Enumerable.Repeat(50, 2); // displayig repeating elements foreach (int ele in num) { Console.WriteLine(ele); } } }Output50 50
Read MoreHow to format message with integer fillers in Java
To format message with integer fillers in Java, we use the MessageFormat class. The MessageFormat class gives us a way to produce concatenated messages which are not dependent on the language. The MessageFormat class extends the Serializable and Cloneable interfaces.Declaration − The java.text.MessageFormat class is declared as follows −public class MessageFormat extends FormatThe MessageFormat.format(pattern, params) method formats the message and fills in the missing parts using the objects in the params array matching up the argument numbers and the array indices.The format method has two arguments, a pattern and an array of arguments. The pattern contains placeholder in {} curly ...
