The Dictionary.Clear() method in C# removes all key/value pairs from the Dictionary.Syntaxpublic void Clear();Let us now see an example to implement the Dictionary.Clear() method −Exampleusing System; using System.Collections.Generic; public class Demo {    public static void Main(){       Dictionary dict =       new Dictionary();       dict.Add("One", "John");       dict.Add("Two", "Tom");       dict.Add("Three", "Jacob");       dict.Add("Four", "Kevin");       dict.Add("Five", "Nathan");       Console.WriteLine("Count of elements = "+dict.Count);       Console.WriteLine("Key/value pairs...");       foreach(KeyValuePair res in dict){          Console.WriteLine("Key = {0}, ...

Consider we have few elements in a linked list. We have to find the multiplication result of last n number of elements. The value of n is also given. So if the list is like [5, 7, 3, 5, 6, 9], and n = 3, then result will be 5 * 6 * 9 = 270.The process is straight forward. We simply read the current element starting from left side, then add the elements into stack. After filling up the stack, remove n elements and multiply them with the prod. (initially prod is 1), when n number of elements are ... Read More

The CharEnumerator.Dispose() method in C# is used to release all resources used by the current instance of the CharEnumerator class.Syntaxpublic void Dispose ();Let us now see an example to implement the CharEnumerator.Dispose() method −Exampleusing System; public class Demo {    public static void Main(){       string strNum = "356";       CharEnumerator ch = strNum.GetEnumerator();       while (ch.MoveNext())          Console.Write(ch.Current + " ");       // disposed       ch.Dispose();       // this will show an error since we disposed the object above       // Console.WriteLine(ch.Current);    } }OutputThis will produce the following output −3 5 6

The CharEnumerator.Clone() method in C# is used to create a copy of the current CharEnumerator object.Syntaxpublic object Clone();Let us now see an example to implement the CharEnumerator.Clone() method −Exampleusing System; public class Demo {    public static void Main(){       string strNum = "356";       CharEnumerator ch = strNum.GetEnumerator();       while (ch.MoveNext()){          Console.Write(ch.Current + " ");          CharEnumerator enumClone = (CharEnumerator)ch.Clone();          while (enumClone.MoveNext())             Console.Write(enumClone.Current + " ");          Console.WriteLine();       }    } }OutputThis will produce the following output −3 5 6 5 6 6

The Char.IsUpper() method in C# indicates whether the specified Unicode character is categorized as an uppercase letter.Syntaxpublic static bool IsUpper (char ch);Above, the parameter ch is the Unicode character to evaluate.Let us now see an example to implement the Char.IsUpper() method −Exampleusing System; public class Demo {    public static void Main(){       bool res;       char val = 'H';       Console.WriteLine("Value = "+val);       res = Char.IsUpper(val);       Console.WriteLine("Is the value an uppercae letter? = "+res);    } }OutputThis will produce the following output −Value = H Is the ...

Consider we have few elements in a linked list. We have to find the multiplication result of first k number of elements. The value of k is also given. So if the list is like [5, 7, 3, 5, 6, 9], and k = 3, then result will be 5 * 7 * 3 = 105.The processes is straight forward. We simply read the current element starting from left side, then multiply it with the prod. (initially prod is 1), when k number of elements are traversed, then stop.Example#include #include using namespace std;    class Node{       public: ... Read More

The Char.IsSymbol() method in C# is indicating whether the character at the specified position in a specified string is categorized as a symbol character.Syntaxpublic static bool IsSymbol (string str, int index);Above, str is a string, whereas the position of the character to evaluate in str.Let us now see an example to implement the Char.IsSymbol() method −Exampleusing System; public class Demo {    public static void Main(){       bool res;       char val = 'P';       Console.WriteLine("Value = "+val);       res = Char.IsSymbol(val);       Console.WriteLine("Is the value a symbol? = "+res); ...

Suppose we have the diameter and the height of the cylinder, we have to find the perimeter of the cylinder. As the perimeter is the outline of two dimensional object, then we cannot find the perimeter of one three dimensional object directly. We can make a cross section of the cylinder, and convert it as rectangle, then find the perimeter. The two sides of the rectangular cross section are the diameter, and the height. So perimeter is −p=(2*d)+(2*h)Example#include using namespace std; int getCylinderPerimeter(int d, int h) {    return (2*d) + (2*h); } int main() {    int diameter = ... Read More
