I am not sure if it is the version but had to change the following lines to eliminate the errors:
float cash = 2.32f;
const char* sandwich = "ham";

[andyroo]

my school basically gave us a textbook and a link to your channel to teach us c++. glad you are actually good.

[Alexander-xoho]

6:55 in visual studio 2017 you dont need to have the star or double quote to do a string you can just do: char sandwitch = 'ham';
just wanted to say

[leechatt]

Thankyou for this! I finally got VS2015 up running and am following your tutorials. Would love to see some tutorials on pixmaps and direct access to pixels as pitch etc.. Keep up your teaching style! I havent got bored one second!

[pangde]

Gotta say Trevor you are awesome with explaining each technicality. My teacher just reads from a power point so I am practically stuck learning everything in terms of implementing it into a compiler to run. Keep up the work.

[kidsparty]

Can you please guide me on How to print in standalone output window instead of console in visual studio?

[kintarios]

Hello there. I wanted to ask is it advisable to avoid using auto? Does it affect performance? When would we use auto and when would we not?

[Freebird]

Note to noob-self: When wondering why the little CMD window will not show up? --Remember to check if it is HIDDEN behind the VS 17 app. DUH! Thanks for a great video Trevor.

[mathiashale]

Is the first challenge to accept input and display the output of the five variables? I have to say I don’t really understand the second challenge. I would be very grateful if you help me.

[odgreat]

Trevor!!!
'<' is called the less than sign ;)

[Ran-wmlt]

Great series that everyone wanting to learn c++ should watch.

As far as Visual Studio 2017 is concerned there is an error in your code related to:
char* sandwich = "ham";
error: a value of type "const char *" cannot be used to initialize an entity of type "char *"
alas, the answer was within the error. changed char" to const char* and problem resolved.

[knifenuturban]

int x;
x = 3;

works fine too right?

[zeynepaydogan]

Great videos! Very detailed and certainly not boring .

[Snail]

thank you from Korea, for all those lectures! One thing I want to check is,
I found out that when using vs2017, you can put the limit of value after the variable name like 'a[10]' so that the error doesn't occur
but still not sure if I can completely replace char* declare this way, can I get an advice about this?

[bend.]

for some reason I could only get the code to work by changing char* to const char*, not sure why though

[BlathoPlay]

(challange), unsigned doesn't work with double, does it?

[phantasmmasquerade]

Question!! spot in video 18:34, why are the positive number off by one...??

[hijackedpickle]

I am getting a error when I press "Local Windows Debugger"
its says "Could not find
was build with /DEBUGFASTLINK which requires object files for debugging. Subsequent failures will be logged to the Debug pane of the output window"

Any help?

[adrianb]

your voice, the cat, and video structure is pretty fun and interesting. thanks
