Data type is an important concept in programming. Data type specifies the size and type of variable values.
Go is statically typed, meaning that once a variable type is defined, it can only store data of that type.
Go has three basic data types
- bool : represents a boolean value and is either true or false
- Numeric : represents integer types, floating point values, and complex types
- string : represents a string value
Example
package main
import ("fmt")
func main() {
var a bool = true
// Boolean var b int = 5 // Integer var c float32 = 3.14 // Floating point number var d string = "Hi!" // String fmt.Println("Boolean: ", a) fmt.Println("Integer: ", b) fmt.Println("Float: ", c) fmt.Println("String: ", d)
}
