Editing Software bug (section)

=== Techniques ===

Programming techniques such as [[programming style]] and [[defensive programming]] are intended to prevent typos.

For example, a bug may be caused by a relatively minor typographical error (typo) in the code. For example, this code executes function {{code|foo}} only if {{code|condition}}is true.

 if (condition) foo();

But this code always executes {{code|foo}}:

 if (condition); foo();

A convention that tends to prevent this particular issue is to require braces for a block even if it has just one line.

 if (condition) {
   foo();
 }

Enforcement of conventions may be manual (i.e. via [[code review]]) or via automated tools.
