My current commenting style, although it needs work. You'll have to excuse it's JavaScript-iness, that's all I have handy.
// ========================================================
// COUNT OCCURRENCES (
// STR, // String to search through
// SUB // String to search for
// )
// --------------------------------------------------------
// Counts the instances of SUB in STR. Counts overlapping
// occurrences. Count_Occurrences( 'rrrrr', 'rr') = 4.
// --------------------------------------------------------
function Count_Occurrences ( STR, SUB ) {
var last = 0;
var count = 0;
while ((last = STR.indexOf(SUB, last + 1)) > -1) { count++ }
return count;
}
Update: If you ever spend a year in a country where they don't speak your language, keep a spell checker handy. Alternatively, if my code is used it will only be by non-english speakers, who wouldn't know how to spell 'occurrence' anyway. ;)
