Golang Program to Print the Sum of all the Positive Numbers and Negative Numbers in a List

Steps

• Read a number of elements to be in a list.
• Take the elements from the user using a for loop and append to a list.
• Using a for loop, get the elements one by one from the list and check if it is positive or negative.
• If it is positive, check if it is odd or even and find the individual sum.
• Find the individual sum of negative numbers.
• Print all the sums.

Example

 Live Demo

package main
import "fmt"
func main() {
   fmt.Printf("Enter the number of elements to be in the list:")
   var size int
   fmt.Scanln(&size)
   var arr = make([]int, size)
   for i:=0; i<size; i++ {
      fmt.Printf("Enter %d element: ", i)
      fmt.Scanf("%d", &arr[i])
   }
   sum1:=0
   sum2:=0
   sum3:=0
   for i:=0; i<size; i++{
      fmt.Println(i)
      if arr[i] > 0{
         if arr[i]%2==0 {
            sum1=sum1+arr[i]
         }else{
            sum2=sum2+arr[i]
         }
      } else {
         sum3=sum3+arr[i]
      }
   }
   fmt.Println("Sum of all positive even numbers:", sum1)
   fmt.Println("Sum of all positive odd numbers:", sum2)
   fmt.Println("Sum of all negative numbers:", sum3)
}

Output

Enter the number of elements to be in the list:4
Enter 0th element: -12
Enter 1 element: 34
Enter 2 element: 35
Enter 3 element: 89
0
