Learn C++ With Me #12 - Switch Statement

[@satvikreddy8662]

Just a note for this video that I think is important to point out. Apart from the switch statement being more elegant, it is also more efficient, especially when you have lots of cases. The reason being, a switch statement is generally implemented with a hash table or a similar data structure, giving you (ideally) an O(1) time complexity to get through the switch. With an if statement, worst-case scenario, you have to compare your variable to every single case, leaving you with an O(n) time complexity, n being the number of cases, which can be slow.

Hence why I'm here. Someone I loathe refuses to use these, and has pages of if/else. I want to be nothing like him, so I'm doubling down.

Can’t wait for the more advanced stuff! Amazing series so far, probably the best 👀 Keep it up, Tim!

[@paulzupan3732]

There's one drawback to the switch statement that's quite important, and that is the fact that the cases in the statement must be compile-time constants. So if you get errors that a variable is not usable in a constant expression or the compiler complains about a call to a non-constexpr function, that's why.

Finally, the tutorial YandereDev need to watch the most LMAO XDD

[@thatdude8368]

Like how you go very in depth to everything em explain everything all the way through

[@aaravgp1332]

I have finally got ther confirmation for vectors, pointers and refferences, which is what I was waiting for in the series

[@mariustrelea5132]

I was waiting for new c++ lesson 😁😁😁

[@Gilmore_Coding]

Nice this one is just like the match case in python

[@Jordan4Ibanez]

Switch statements create jump tables when they are compiled into machine code, for a huge list that, let's say is running 165 times a second in a list of 1000 items, this performance improvement can be EXTREME

Thanks for you content Tim ;)

[@user-sy3ny1sz2w]

Switch statement can't use string a.k.a "std::string" and C string a.k.a "const char*" as expression.

What chair are you using dude?

My education system failed, this youtube man excelled

[@yourdadsbestfriend7101]

yes tim!

[@mbmeweg293]

Thank ya)

[@pravachanpatra4012]

Can you make more pygame and tutorials please in python.

[@keshav.mishra]

Tim! Which degree are you doing Bsc (computer science) or Btech (computer science)

[@bobdeath5]

How much focus will you be putting on creating graphics or seperate windows in future videos?

[@lemahtab]

So, this is similar to SQL's CASE statement, right? Don't need it but is better than IF ELSE in some cases.

[@snknoid]

pls make video 5 ideas for game in pygame

[@JimPageGD]

Cool
