- 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.
Enter the number of elements to be in the list: 4 Element: -12 Element: 34 Element: 35 Element: 89 Sum of all positive even numbers: 34 Sum of all positive odd numbers: 124 Sum of all negative numbers: -12 | Enter the number of elements to be in the list: 5 Element: -45 Element: -23 Element: 56 Element: 23 Element: 7 Sum of all positive even numbers: 56 Sum of all positive odd numbers: 30 Sum of all negative numbers: -68 |
Example
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 1 2 3 Sum of all positive even numbers: 34 Sum of all positive odd numbers: 124 Sum of all negative numbers: -12
