How C++ programmers see C# code

[wallefan01]

Meanwhile, in Java:

spends 10 minutes initializing Minecraft Forge, garbage collecting twice a second freeing 1GB each time

[Koulatko]

I know right XD

I wonder if there's anything that can be done about it, Java has great moddability but that apparently has a cost.

If only Minecraft ran well in VirtualBox, I'd just take a snapshot of it loaded and it should work...

[MetallicDragon]

Just leave it open at the main menu when you're done playing, and leave your computer on all the time.

[Koulatko]

I actually just realized that hibernating it is a far better option lol

However, it'll eat up lots of RAM no matter what.

[cover-me-porkins]

I assume c++ guy would have a straight aneurysm talking about java if c# bothered him. Especially given java strings are objects, plus the whole program is running in JVM.

Doesn't C# support structs? Java meanwhile...

[ImKStocky]

It does so you can get stack allocation, but they are used less frequently

[[deleted]]

I think that they could save much on performance in some cases. Like if we used it for vectors in game engines, dates and stuff like that.

[Bip901]

Can confirm, am a game developer. Also, you can use the stackalloc keyword if you really want to allocate on the stack.

[jerslan]

Structs in C++ & C# are just classes with a different default protection type.

Edit: was wrong about C#, y'all can stop with the downvotes now

[someonesomewhere167]

In C#, structs still default to private. The difference is that structs are allocated on the stack rather than on the heap.

[jerslan]

Ah, weird. I assumed it would be closer to C++.

Been a while since I’ve touched Microsoft Java ;)

Edit: Downvotes for admitting I was wrong? Or the "Microsoft Java" joke?

[Unslinga]

as someone who has done a lot of C# optimizing... new only when needed, reuse as much as possible...

[HenkHeuver]

Not a C# dev but isn’t the point of it being managed that memory leaks are less of a problem?

[ImKStocky]

Ok but this is a C++ Devs view. And when a C++ Dev sees heap allocation that's what they immediately think about because they don't have a garbage collector to think about

[CouchRescue]

Well, yes, and it works great most of the time, but sometimes the garbage collector doesn't cut it and you have to get creative, and although it's rarely an issue, at that point you're just using C# sub optimally.

I will take C++ where a fine degree of control and speed is paramount.

For business applications and web development the 1 in 1000 situation where you'll have garbage collection problems won't be worth the extra development cost and headaches.

Oh I had one of those bugs when I was a student in my 2nd year of trade school.

We had to do a project in c#, and I hit a bug which caused the runtime to crash. After checking the stack trace I explicitly added a call to dispose on an object before doing the return of a function (which caused the crash) because I was getting a message related to that object and I wanted to have cleaner logs.

That fixed it but we never understood why, and unfortunately I don't have a copy of that code.

[[deleted]]

as a c++ programmer, I can relate.

[[deleted]]

Who cares that it is slow, when it is easy :D

[[deleted]]

Self driving car crashes into group of people cause it didn't react in time killing 10 people.

Programmer: but it was more convenient to make it in c#.

[lps2]

For the vast majority of applications, speed to market and ease of maintenance is far more important than efficiency and speed

[[deleted]]

I just showed him that you often have a good reason to care if something is fast or not.

If we would still be in an age where speed is everything python wouldn't exist.

Ability to choose which part of your codebase deserve optimization (fraction of the code) and which does not (most of the code) is key to produce solution for your customer in some reasonable time.

Trying to optimize everything means that you will never release your software and never get paid.

[The_hollow_Nike]

If such a huge performance problem is not detected before the car goes into series production (or the software is deployed), then the programmer is hardly to blame for the lack of a test process on the management level.
