Go by Example:functions

function is the core of go, and we will learn about functions through a number of different examples.

Package Mainimport "FMT"    //This function inputs two int data, calculates and returns the int type and the Func plus (a int, b int) int {    //GO need to return the value    explicitly using the return statement It does not automatically return the value of the last expression in the function.    return a + b}func main () {    //As you would think, call the function res through "name (args)"    : = Plus (1, 2)    FMT. Println ("1+2 =", res)}

Output

$ go Run functions.go 1+2 = 3

The functions of the go language also have some other functions. One of these is the multi-valued return that will be learned in the next section.
