Golang hello Examples

Example #1

File: sum_hello.go Project: jemoonkim/golangbook

func main() {
	var a, b int = 1, 2
	r := C.sum(C.int(a), C.int(b)) // C 언어 함수 sum 호출
	fmt.Println(r)                 // 3

	C.hello() // Hello, world!
}

Example #2

File: rand.go Project: kangaukju/golang

func main() {
	r := C.rand()
	fmt.Println(r)

	var a, b int = 10, 20
	r = C.sum(C.int(a), C.int(b))
	fmt.Println(r)

	r = C.sum(C.int(20), C.int(30))
	fmt.Println(r)

	C.hello()
}

	Seed(1000)

	fmt.Println(int(C.random()))
