This document discusses primitive data types in programming including numerical types like integers and floats which have defined value ranges, Booleans to represent true/false values, and characters which are single characters represented by strings. It provides examples of declaring and assigning values to variables of each type, showing integers can be 8, 16, 32 or 64 bits, floats allow decimal values, and characters are single characters between quotes rather than numbers.
Primitive types
- 1. PRIMITIVE TYPES -Primitive types -Ranges of values that each type can represent -Where each type would be used best
- 2. Numerical types: Ints, Floats, Doubles Let int1 : Int = 0 Let int2 : Int8 = 127 Let int3 : Int Let int4 = 54 Let int3: Uint = -2 cannot assign negative value to Uint Let float1 : Float = 54.5 Let double1 : Double = 54.6 Let double2 : Double = 5
- 3. Boolean : true/false Let bool1 : Bool = false Let bool2 : Bool = 5 > 3 *testing condition
- 4. Character One digit in length, between Let char1 : Character = ? Let char2 : Character = 息 Let char3 : Character = 5 just a character, not number Let char4 : Character = not allowed
