Instructions

Write a function that takes two numbers and adds them together if they are both positive.

• If either number is negative or one of them is negative and the other is positive return 0.

Expected function

func AddIfPositive(a int, b int) int {
    // your code here
}

Usage

Here is a possible program to test your function:

package main

import "fmt"

func main() {
    fmt.Println(AddIfPositive(1, 2))
    fmt.Println(AddIfPositive(1, -2))
    fmt.Println(AddIfPositive(-1, 2))
    fmt.Println(AddIfPositive(-1, -2))
    fmt.Println(AddIfPositive(10,20))
    fmt.Println(AddIfPositive(0,20))
}

and the output should be:

$ go run .
3
0
0
0
30
