What do switch statements do and How do you use them? I tried the w3schools page on it but didn't understand it very well.

switch statements are almost the same as if statements, they're just designed to be larger.
for example:


is much faster than doing the same thing with if statements.
the "default" will be done if none of the cases return true.

switch statements are more than if statements. switch statement is more efficient than if else statements in terms of efficiency (number of cpu cycles will be less) , code looks clean as well.

Welcome to the Ranch

The disadvantage of switch is that the values must be compile-time constants.
