Functions in Go
In Go, functions are blocks of code that perform specific tasks, which can be reused throughout the program to save memory, improve readability, and save time. Golang functions may or may not return a value to the caller.
Things to know about functions in Golang
For example:
package main
import "fmt"
// multiply() nhân 2 số nguyên và trả về kết quả
func multiply(a, b int) int {
return a * b
}
func main() {
result := multiply(5, 10)
fmt.Printf("multiplication: %d", result)
}
Result:
multiplication: 50Function syntax in Golang
func function_name(Parameter-list)(Return_type) {
// function body...
}Function declaration
In Go, a function is declared with the func keyword, followed by a name, parameters, and optional return type.
Syntax
func function_name(Parameter-list)(Return_type) {
// function body...
}Multiply function example
func multiply(a, b int) int {
return a * b
}func: Keyword to declare a function.
function_name: Name of the function, for example: multiply.
Parameter-list: a, b int—the parameters along with their types.
Return_type: int specifies the return type.
Call function
To use a function, simply call it by its name with any necessary arguments. Here, multiply(5, 10) calls the function with 5 and 10 as arguments.
For example
result := multiply(5, 10)
fmt.Printf("Result of multiplication: %d", result)Function arguments
Go supports two ways to pass parameters to a function: Call by value and Call by reference. By default, Go uses call by value, which means that values are copied and changes inside the function do not affect the caller's variables.
Call by value
In call by value, the values of the arguments are copied into the function parameters, so changes in the function do not affect the original variables.
For example:
package main
import "fmt"
func multiply(a, b int) int {
a = a * 2 // chỉnh sửa bên trong hàm này
return a * b
}
func main() {
x := 5
y := 10
fmt.Printf("Before: x = %d, y = %d\n", x, y)
result := multiply(x, y)
fmt.Printf("multiplication: %d\n", result)
fmt.Printf("After: x = %d, y = %d\n", x, y)
}
Result:
Before: x = 5, y = 10
multiplication: 100
After: x = 5, y = 10Call by reference
In call by reference, pointers are used so that changes inside the function are reflected in the caller's variables.
For example:
package main
import "fmt"
func multiply(a, b *int) int {
*a = *a * 2 // chỉnh sửa giá trị của a ở địa chỉ bộ nhớ của nó
return *a * *b
}
func main() {
x := 5
y := 10
fmt.Printf("Before: x = %d, y = %d\n", x, y)
result := multiply(&x, &y)
fmt.Printf("multiplication: %d\n", result)
fmt.Printf("After: x = %d, y = %d\n", x, y)
}
Result
Before: x = 5, y = 10
multiplication: 100
After: x = 10, y = 10How to Fix Microsoft Teams Update Error 0x80070002
