Coupling refers to the usage of an object by another object. It can also be termed as collaboration. This dependency of one object on another object to get some task done can be classified into the following two types −Tight coupling - When an object creates the object to be used, then it is a tight coupling situation. As the main object creates the object itself, this object can not be changed from outside world easily marked it as tightly coupled objects.Loose coupling - When an object gets the object to be used from the outside, then it is a loose coupling ...

To check for all vowels, firstly set the condition to check −string res = str.Where(chk =< "aeiouAEIOU".Contains(chk)).Distinct();Above, we have used the string −string str = "the quick brown fox jumps over the lazy dog";Now, using the Any() method checks whether the string has any vowels or not −if(!res.Any()) Console.WriteLine("No vowels!");Loop through the string to get the vowels −Exampleusing System; using System.Linq; public class Program { public static void Main() { string str = "the quick brown fox jumps over the lazy dog"; var res = str.Where(chk =< "aeiouAEIOU".Contains(chk)).Distinct(); ...

To get the binary of Decimal, using recursion, firstly set the decimal number −int dec = 30;Now pass the value to a function −public int displayBinary(int dec) { }Now, check the condition until the decimal value is 0 and using recursion get the mod 2 of the decimal num as shown below. The recursive call will call the function again with the dec/2 value −public int displayBinary(int dec) { int res; if (dec != 0) { res = (dec % 2) + 10 * displayBinary(dec / 2); Console.Write(res); return ...

Read MoreC# program to check whether a given string is Heterogram or not
Heterogram for a string means the string isn’t having duplicate letters. For example −Mobile Cry LaptopLoop through each word of the string until the length of the string −for (int i = 0; i < len; i++) { if (val[str[i] - 'a'] == 0) val[str[i] - 'a'] = 1; else return false; }Above, len is the length of the string.Let us see the complete code −Exampleusing System; public class GFG { static bool checkHeterogram(string str, int len) { int []val = new int[26]; for (int i = ...
