Conditional statements are used to perform different actions based on different conditions.
Use the switch statement to select one of many blocks of code to be executed.
execute code block 1
execute code block 2
code to be executed if n is different from case 1 and 2
This is how it works: First we have a single expression n (most often a variable), that is evaluated once. The value of the expression is then compared with the values for each case in the structure. If there is a match, the block of code associated with that case is executed. Use break to prevent the code from running into the next case automatically.
