Other real life examples for macros would be to target different platforms. You write a conditional to decide between using Windows API or POSIX API. Or you want to do different stuff for an ARM build compared to x86. In open source projects macros are often used for optional features which might be enabled during configuration, like building ffmpeg with lots of optional third party libraries enabled. You can use macros to enable compiler specific stuff, like telling msvc right in the code to link against a library, but you want that part to be "excluded" for other compilers that don't understand or need this. Macros may also play a role when you build static libraries and DLLs for Windows, as the symbols in a header file need to be declared as either importing or exporting code or none of that.
#define true Aladdin
#define false Aladdin
You would have made an excellent Unreal Engine C++ trainer. Please do consider making a course on UE C++

Hi, your videos are very good in terms of content, but will be nice if you improve the audio quality.
Nice explaination 👍🏻
Define macros are easy, the difficult is to read, most of the time you don't know where they are and what they do. Some code depend of some macros to be defined and the docs sometimes don't put so much effort in explain it, and that's really confusing.
Can i use macros to code in another language? By language i mean other than English.
Never mind, apparently I broke my ten beer limit, so this one is on me.
Good tutorial but if you use #define LOG(x), without anything, it compiles and works fine but the error code i get is weird? not 0 or 1.
For people having issues for ifdef DEBUG not showing correctly.
Use #Ifdef _DEBUG
I think the visual studio 2019 changed something for the debug 🙂
Awesome.
You are an excellent teacher.
OMG thank you.This is exactly what i was looking for. OPEN_CURLY it is. No.. WAIT
actually the
LOG(…);
in release mode would become
;
because the semicolon was not defined in the macro.
Let's make Python with #define 😂
if Anyone is watching this in 2020. If your Debug Code is not recognized after checking for PR_DEBUG you just need _DEBUG now. Hope this helps.
#define __m__func_t_ int main() opencurly WAIT semicolon closecurly
These have got to be the most concise and clear programming videos I've seen thus far.
#define true rand()>10
@3:02
Damn,
That was useful
Because I don't like to type
"std::cout<<"
all the time
so i define it as macro.
So he finally defines std::cin.get() at video 55.Well good job
Just a joke.
This video was quite helpful.
Could you please make a similar video but using VSCode? Thank you in advance!
Elegancko
Thanks
#define true (rand()%100 > 5)
The thought of seeing an “OPEN_CURLY” macro in real life cracked me up…at that point you know you’re dealing with a high-effort troll lmao
The worst one I have ever seen is:
#define private public
Awesome!
I am learning SOOOO much more than what i did i uni!
why is this so funny to me. I need to grow up and get my big boy coder pants.
So in Release mode even if you have LOG("Hello") it will not call it? or will call it and not do anything? Because LOG(Hello) is in the int main()
you are right at 6:13 but we can do the //comment and say that std::cin.get() called here etc..
std::string Cherno[1000000]={" Thank You 🙂 "};
3:50 you're welcome
Wouldn't it be usually better to use inline functions instead? They are safer and the performance difference is negligible. I know function calls use more cpu cycles but from my understanding inline functions are very optimized. I remember this from Effective C++ book
Do you do any consulting?
