Read MoreHow to access array elements using a pointer in C#?
In C#, an array name and a pointer to a data type same as the array data, are not the same variable type. For example, int *p and int[] p, are not the same type. You can increment the pointer variable p because it is not fixed in memory but an array address is fixed in memory, and you can't increment that.Here is an example −Exampleusing System; namespace UnsafeCodeApplication { class TestPointer { public unsafe static void Main() { int[] list = {5, 25}; fixed(int *ptr = ...
Read MoreJava program to calculate the GCD of a given number using recursion
You can calculate the GCD of given two numbers, using recursion as shown in the following program.Exampleimport java.util.Scanner; public class GCDUsingRecursion { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Enter first number :: "); int firstNum = sc.nextInt(); System.out.println("Enter second number :: "); int secondNum = sc.nextInt(); System.out.println("GCD of given two numbers is ::"+gcd(firstNum, secondNum)); } public static int gcd(int num1, int num2) { if (num2 != 0){ return gcd(num2, num1 % num2); } else{ return num1; } } }OutputEnter first number :: 625 Enter second number :: 125 GCD of given two numbers is ::125
