Selection

Selection uses if statements and switch statements.

• if statements work by performing an action only if a condition is reached.

1  if (a > b)
2             { Console.WriteLine("A is greater than B"); }

I can also be paired with else, which will perform an action if the "if" condition is not met.

• switch is basically a combined if and if else statement, and is used for a lot of different options.

1 switch(x)
2   { case 1:
3          x++
4         break;
5     case 2:
6          x--
7         break;
8   }

Default is an optional part of the switch method, which is used in case none of the other conditions are met.

 1 switch(x)
 2   { case 1:
 3          x++
 4         break;
 5     case 2:
 6          x--
 7         break;
 8      default:
 9           x*= x
10         break;
11 }
