What are decision making statements in C#?

Csharp Programming Server Side Programming

Decision making statements requires the programmer to specify one or more conditions to be evaluated or tested by the program, along with a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false.

The following are the types of decision making statements −

Sr.No	Statement & Description
1	if statement An if statement consists of a boolean expression followed by one or more statements.
2	if...else statement An if statement can be followed by an optional else statement, which executes when the boolean expression is false.
3	nested if statements You can use one if or else if statement inside another if or else if statement(s).
4	switch statement A switch statement allows a variable to be tested for equality against a list of values.
5	nested switch statements You can use one switch statement inside another switch statement(s).

Let us see an example of if-else decision making statement in C#.

using System;

namespace Demo {
   class Program {
      static void Main(string[] args) {
         int a = 50;

         if (a < 10) {
            Console.WriteLine("a is less than 10");
         } else {
            Console.WriteLine("a is not less than 10");
         }
         Console.WriteLine("a = {0}", a);
         Console.ReadLine();
