Basic Syntax and Data Types in Go 📝

Go features a straightforward syntax resembling C but with modern enhancements. Here are some foundational elements:

• Variables: Declared using var or shorthand :=
• Constants: Declared with const
• Data Types: int, float64, string, bool, arrays, slices, maps, structs

Example: Variable Declaration

package main

import "fmt"

func main() {
    var age int = 30
    name := "Alice"
    const Pi float64 = 3.1415
    fmt.Println("Name:", name, ", Age:", age, ", Pi:", Pi)
}

Data Types Overview:

| Type                           | Description                        |
|--------------------------------|------------------------------------|
| int, int8, int16, int32, int64 | Integer types of varying sizes     |
| float32, float64               | Floating point numbers             |
| string                         | Text data                          |
| bool                           | Boolean values (true/false)        |
| arrays                         | Fixed-length sequences of elements |
| slices                         | Dynamic arrays                     |
| maps                           | Key-value pairs                    |
| struct                         | Composite data types for objects   |

Mastering syntax allows you to write clear, efficient, and idiomatic Go code.
