Avoid `do`-statements

Reason

Readability, avoidance of errors. The termination condition is at the end (where it can be overlooked) and the condition is not checked the first time through.

Example

int x;
do {
    cin >> x;
    // ...
} while (x < 0);

Note

Yes, there are genuine examples where a do-statement is a clear statement of a solution, but also many bugs.

Enforcement

Flag do-statements.
