C# Program to order array elements
Use ThenBy() method to order array elements. Let’s say we have the following string array.string[] str = { "Sandler", "Jack", "Tom", "Matt", "Henry", "Johnny" };Now, use Lambda Expressions and set a condition inside the ThenBy() method to sort the strings according to the number of characters they have.IEnumerable res = str.AsQueryable().OrderBy(alp => alp.Length).ThenBy(alp => alp);Here is the entire example to order array elements using ThenBy() method.Exampleusing System; using System.Linq; using System.Collections.Generic; public class Demo { public static void Main() { string[] str = { "Sandler", "Jack", "Tom", "Matt", "Henry", "Johnny" }; IEnumerable res ...
Read MoreDifference between strlen() and sizeof() for string in C
strlen()The function strlen() is a predefined function in C language. This is declared in “string.h” header file. It is used to get the length of array or string.Here is the syntax of strlen() in C language, size_t strlen(const char *string);Here, string − The string whose length is to be calculated.Here is an example of strlen() in C language, Example#include #include int main () { char s1[10] = "Hello"; int len ; len = strlen(s1); printf("Length of string s1 : %d", len ); return 0; }OutputLength of string s1 : 10In the above example, ...
Read MoreThe # format flag in Java
Apply the # flag to the %o, %x, %e, and %f format specifiers. If you want to display the hexadecimal number with a 0x prefix, then precede the %x specifier with #.Preceding the %x specifier with a #, the hexadecimal number will be printed with a 0x prefix.Let us see an example wherein $e is used. It includes a decimal point, even if the decimal digits are not present −Exampleimport java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); System.out.println(f.format("%#e", 5F)); } }Output5.000000e+00
Read Moreatexit() function in C/C++
The function atexit() is used to call the function after the normal exit of program. The program is called without any parameters. The function atexit() is called after exit(). The termination function can be called anywhere in the program. This function is declared in “stdlib.h” header file.Here is the syntax of atexit() in C language, int atexit(void (*function_name)(void))Here, function_name − The function is to be called at the time of termination of program.Here is an example of atexit() in C language, Example#include #include void func1 (void) { printf("Exit of function 1"); } void func2 (void) { ...

Perform Union on two sequences using the Queryable Union method.The following are our arrays.int[] arr1 = { 29, 40, 15, 55, 70, 30, 90 }; int[] arr2 = { 30, 36, 40, 18, 15, 55, 75 };Now, get the Union of the arrays using the Union method.arr1.AsQueryable().Union(arr2);Exampleusing System; using System.Linq; using System.Collections.Generic; public class Demo { public static void Main() { int[] arr1 = { 29, 40, 15, 55, 70, 30, 90 }; int[] arr2 = { 30, 36, 40, 18, 15, 55, 75 }; IEnumerable res = arr1.AsQueryable().Union(arr2); foreach (int a in res) Console.WriteLine("{0} ", a); } }Output29 40 15 55 70 30 90 36 18 75
Read MoreOperator Functions in Python
In Python there are some additional standard library methods for mathematical operations, like arithmetic, logical, relational, bitwise etc. operations. These methods can be found under the operator module. To use it at first we need to import it the operator standard library module. import operator In this section we will see some operator functions for bitwise operations and container operations. Arithmetic Operations At first we will see the arithmetic operating functions. These are like below. Sr.No Functions & Description 1 add(x, y) The add() method is used to add two numbers x and y. ...
Read MoreGet the width and height of a three-dimensional array
Let’s say our three-dimensional array is −int[,,] arr = new int[3,4,5];To get the height and width i.e. the rows and columns.Array.GetLength(0) – for rows Array.GetLength(1) – for columnsExampleusing System; class Program { static void Main() { int[,,] arr = new int[3,4,5]; Console.WriteLine(arr.GetLength(0)); Console.WriteLine(arr.GetLength(1)); Console.WriteLine(arr.GetLength(2)); } }Output3 4 5
Read MoreJava Program to shift bits in a BigInteger
To shift bits in a BigInteger, use the shiftLeft() or shiftRight() method.shiftLeft() methodThe java.math.BigInteger.shiftLeft(int n) returns a BigInteger whose value is (this > n). Sign extension is performed. The shift distance, n, may be negative, in which case this method performs a left shift. It computes floor(this / 2n).Exampleimport java.math.*; public class Demo { public static void main(String[] args) { BigInteger one; one = new BigInteger("25"); one = one.shiftRight(3); System.out.println("Result: " +one); } }OutputResult: 3
Read MoreC# Program to convert a Double value to an Int64 value
To convert a Double value to an Int64 value, use the Convert.ToInt64() method.Int64 represents a 64-bit signed integer.Let’s say the following is our double value.double val = 23.951213e12;Now to convert it to Int64.long longVal = Convert.ToInt64(val);Let us see the complete example.Exampleusing System; public class Demo { public static void Main() { double val = 23.951213e12; long longVal = Convert.ToInt64(val); Console.WriteLine("Converted double {0:E} to Int64 {1:N0} value ", val, longVal); } }OutputConverted double 2.395121E+013 to Int64 23,951,213,000,000 value
Read MoreHow do you use ‘foreach’ statement for accessing array elements in C#
To access Array elements in a foreach statement, use the numeric index.Let’s say the following is our code.Exampleusing System; namespace ArrayApplication { class MyArray { static void Main(string[] args) { int [] n = new int[10]; /* n is an array of 10 integers */ /* initialize elements of array n */ for ( int i = 0; i < 10; i++ ) { n[i] = i + 100; } ...
