QString, QStringLiteral, Value Types

Comment: Maybe this could be more general as well: String handling and value types

Back to Week 1

Objective: Basic String manipulation

Comment: There is no String type in Qt, so should be written on lower-case

Comment: This is a huge topic and I'd try to avoid losing attendees' interest at the beginning. The minimum: QString + QChar + QCodec, creating, concatenation + light-weight use with QLatin1String or QStringView (the latter can be omitted). String literals could be already another topic. And QByteArray is relevant in cases, where coding is not needed. I'm afraid this is too much for one section, isn't it.
