Selection with switch

Many languages provide you with a switch or case statement that can be used to choose between different paths based upon matching values.

Switch statements …

• will select the path where the case matches the value in the switch
• do not have visible conditions, but they are behind the scenes.
• use a condition that checks if the switch’s value equals each case.

Tip

You will use the if statement much more than switch/case, but switch/case can be useful when you have a known list of values to choose between.

Example

using static SplashKitSDK.SplashKit;

// You can create boolean variables to store true/false values.
// There are also keywords for true and false
bool ready = false;


WriteLine(" a - say hello");
WriteLine(" b - say bye");
WriteLine(" c - say Ni!");
WriteLine();
Write("Enter option: ");
string line = ReadLine();

// Switch to the case that matches the value in line
switch(line)
{
  case "A":
  case "a":
    WriteLine("Hello");
    break;
  case "B":
  case "b":
    WriteLine("Bye");
    break;
  case "C":
  case "c":
    WriteLine("Ni!");
    break;
  case "D":
  case "d":
    WriteLine("Superpowers unlocked!");
    break;
  default:
    WriteLine("Please choose one of the indicated options");
    break;
}
