C#, switch, statement Switch statement in c sharp(Creating calculator in c#) A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each switch case. The following rules apply to a switch statement − The expression used in a switch statement must have an integral or enumerated type, or be of a class type in which the class has a single conversion function to an integral or enumerated type. You can have any number of case statements within a switch. Each case is followed by the value to be compared to and a colon. The constant-expression for a case must be the same data type as the variable in the switch, and it must be a constant or a literal. When the variable being switched on is equal to a case, the statements following that case will execute until a break statement is reached. When a break statement is reached, the switch terminates, and the flow of control jumps to the next line following the switch statement. Not every case needs to contain a break. If no break appears, the flow of control will fall through to subsequent cases until a break is reached. A switch statement can have an optional default case, which must appear at the end of the switch. The default case can be used for performing a task when none of the cases is true. No break is needed in the default case. using System; namespace DecisionMaking { class Program { static void Main(string[] args) { /* local variable definition */ char grade = 'B'; switch (grade) { case 'A': Console.WriteLine("Excellent!"); break; case 'B': case 'C': Console.WriteLine("Well done"); break; case 'D': Console.WriteLine("You passed"); break; case 'F': Console.WriteLine("Better try again"); break; default: Console.WriteLine("Invalid grade"); break; } Console.WriteLine("Your grade is {0}", grade); Console.ReadLine(); } } } ...................................................................................................
