: something that should be constantly real at a offered position (or points) of a method; generally utilised to explain the point out (set of values) of an item or perhaps the condition of the loop before entry into your recurring statement.

Regular types which include vector is often modified to execute bounds-checks underneath the bounds profile Full Article (in a suitable way, like by including contracts), or utilized with at().
