why visual studio 2022 can't compile it

Question

why visual studio 2022 can't compile it

alaamer 1

I found a code in a book for the C++ language. The important thing is that I ran this code on Visual studio 2022. It didn't work.
I tried it on codeblocks. it didnt work
I tried it on any online (compilers) on Google, it worked
so whats the problem?
Note: I am not the one who wrote it, I just copied it from the book

Don't you get list of errors ...

As we don't know your source code there it's impossible to guide you other but look the errors compiler gives first and if there aren't errors reported then post the code as Castorix31 suggests.

Hi @alaamer ,

I tried it on any online (compilers) on Google, it worked.

The cause of this phenomenon may be that the compiler lacks necessary components. I suggest you install the C++ compilation environment in visual studio installer.

Hi alaamer,

Since I don't have code, I couldn't give an exact answer. I guess it may be because VS automatically turned on -permissive, you could turn it off and try to run the code.

Another issue may be that the Microsoft C++ compiler uses switches to determine which version of the language standard to compile. For example, if the code you are trying to compile uses C++ 20 language features, you need to pass /std:c++20 to the compiler if you are using the command line compiler. If you are using Visual Studio, then you right click your project in solution explorer > properties > C/C++ > Language and set the C++ Language Standard dropdown to ISO C++20 Standard (/std:c++20).

As others have said, w/o knowing what you are trying to compile, there is little additional help we can offer.
