    Study Notes

    Syntax

    Variables

    • Declared using the var keyword
    • Can be declared at the package or function level
    • Must be initialized before use
    • Example: var x int = 10

    Data Types

    • Integers: int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64
    • Floats: float32, float64
    • Complex: complex64, complex128
    • Boolean: bool
    • String: string
    • Arrays: []T, where T is the type of the elements
    • Slices: []T, similar to arrays, but dynamic size
    • Structs: struct { field1 T1; field2 T2; ... }
    • Pointers: *T, where T is the type of the variable

    Control Flow

    • If: if condition { code }
    • If-Else: if condition { code } else { code }
    • Switch: switch expression { case value1: code; case value2: code; ... }
    • For: for init; condition; post { code } or for range := range expression { code }
    • Range: range keyword used to iterate over arrays, slices, or strings
    • Break: break statement used to exit a loop or switch
    • Continue: continue statement used to skip to the next iteration of a loop

    Functions

    • Declaration: func name(param1 type1, param2 type2, ...) return_type { code }
    • Function Calls: name(arg1, arg2, ...)
    • Return: return statement used to return values from a function
    • Multiple Return Values: return val1, val2, ...

    Error Handling

    • Error Type: error type used to represent errors
    • Error Values: nil represents no error
    • Panic: panic function used to stop the execution of the program and return an error
    • Recover: recover function used to regain control of a panicking program

    Variables

    • Declared using the var keyword
    • Can be declared at the package or function level
    • Must be initialized before use
    • Example: var x int = 10

    Switch Statements

    • switch expression { case value1: code; case value2: code;...}

    Loops

    • for init; condition; post { code }
    • for range := range expression { code }
    • range keyword used to iterate over arrays, slices, or strings

    Break and Continue

    • break statement used to exit a loop or switch
    • continue statement used to skip to the next iteration of a loop

    Functions

    Function Declaration

    • func name(param1 type1, param2 type2,...) return_type { code }

    Function Calls

    • name(arg1, arg2,...)

    Error Handling

    Error Type

    • error type used to represent errors

    Error Values

    • nil represents no error

    Panic and Recover

    • panic function used to stop the execution of the program and return an error
    • recover function used to regain control of a panicking program

    Occurrence and Habitat of Algae

    • Algae can be found in various habitats, including:
      • Hydrophytes: submerged or free-floating on the surface of water
      • Epiphytes: growing on other plants
      • Epizoophytes: growing on animals such as mollusks, shells, fish, and turtles

    Five Kingdom Classification

    • The five kingdoms of classification are:
      • Monera
      • Protista
      • Fungi
      • Plantae
      • Animalia

    Modern Classification of Algae

    • Modern classification of algae is based on:
      • Pigments: kinds and relative amounts
      • Other criteria, including:
        • Physiological and biochemical characteristics (thanks to modern techniques)
        • Electron microscopy (EM) observations
        • Laboratory culturing of algae

    Distribution of Algae

    • Algae can be found in:
      • Fresh water: abundantly in ponds, lakes, slow-running streams, and water reservoirs
      • Salt water: in marine environments
