Video Description
Master the fundamental building blocks of C#! Every piece of data has a type, and understanding types is crucial.
What you'll learn: • What variables are (named storage locations) • Declaring variables with types • Common built-in types (string, int, double, bool, DateTime) • Choosing the right type (decimal for money!) • Type inference with 'var' • Constants with 'const' • Preview of value vs reference types • Nullable types with ? • Type conversion and casting
Key insight: C# is strongly typed - this catches errors before your program runs!
Common types covered: • Text: string, char • Numbers: int, double, decimal • Logic: bool • Dates: DateTime
