Thread: C++ and C#

I try to learn C# and it said that it is a good practice to limit 25 lines of code in one function. If it is more than that, you have to break into another function. What about C++? Do we have such advice? What is the limit to put lines of code in one function in C++?

In C#, code like this:

Code:

int main() {

     Detroit_Pistons() {
   
     }

}

is bad. The good one is like this:

Code:

int main()
{

      Detroit_Pistons()
      {

      }


}

But if I were not mistaken, in C++ both style are good. So I just wonder why C# developers are such weird people?

Sorry it should be:

Code:

int main() {

}

Detroit_Pistrons() {

}

and:

Code:

int main()
{
    
}

Detroit_Pistrons() 
{

}

I'm pretty sure it's a matter of taste which way you do it. Personally I prefer this way:

Code:

int main()
{
    return 0;
}

As opposed to this way:

Code:

int
main() {
    return 0;
}

But other people are different.

I don't think any language limits it as such - the limit is imposed by programmer discipline in terms of producing readable code.

It basically boils down to this - if you can't see the whole function on one screen / page, then it may be too complicated.
There are however exceptions - for example a command decoder may be many hundreds of lines long, yet perfectly clear to any reader.

The compiler won't care whether a function is 10 or 1000 lines long, but your maintainer might.
