Use K&R-derived layout

Reason

This is the original C and C++ layout. It preserves vertical space well. It distinguishes different language constructs (such as functions and classes) well.

Note

In the context of C++, this style is often called "Stroustrup".

This is a recommendation for when you have no constraints or better ideas. This rule was added after many requests for guidance.

Example

struct Cable {
    int x;
    // ...
};

double foo(int x)
{
    if (0 < x) {
        // ...
    }

    switch (x) {
    case 0:
        // ...
        break;
    case amazing:
        // ...
        break;
    default:
        // ...
        break;
    }

    if (0 < x)
        ++x;

    if (x < 0)
        something();
    else
        something_else();

    return some_value;
}

Note the space between if and (

Note

Use separate lines for each statement, the branches of an if, and the body of a for.

Note

The { for a class and a struct is not on a separate line, but the { for a function is.

Note

Capitalize the names of your user-defined types to distinguish them from standards-library types.

Note

Do not capitalize function names.

Enforcement

If you want enforcement, use an IDE to reformat.
