What is the difference between if statement and switch?

Answer 1

If u have many cases u should use switch case instead of writing else if many times

Answer 2

Switch is if you have a list of different options for outcomes but all of the same type. Often, days of the week are used, but it could be something like animals or a sequence of numbers.
"If" or "else if" could handle this too but would take more coding, as Muhammad said.
E.g. (forgive the basic/sloppy psuedo-code)
Switch(animals)
Case 1: cat
//code
Case 2: snake
// code
Case n: other animal
//code

Or
Switch(number sequence)
Case 1: 1357
//code
Case 2: 14159
//code
Case n: other sequence of numbers
//code

Is similar to:
If(animal == cat)
//code
Else if(animal == snake)
//code
Else if(animal == other animal)
//code

And so on... I hope that helps!

Answer 3

In switch statement you can't use the relational operators like '<' and '>'

But, you can use in if statement.
