# Go Program to find Sum of Odd Numbers

This Go program to find the Sum of Odd Numbers from 1 to n uses the for loop to iterate between 1 and n. Inside the loop, if statement filters the odd numbers and adds total to odd total.

```package main

import "fmt"

func main() {

var oddnum, Oddtotal int

fmt.Print("Enter the Number to find Odd Sum = ")
fmt.Scanln(&oddnum)

Oddtotal = 0
fmt.Println("List of Odd Numbers from 1 to ", oddnum, " are = ")
for x := 1; x <= oddnum; x++ {
if x%2 != 0 {
fmt.Print(x, "\t")
Oddtotal = Oddtotal + x
}
}
fmt.Println("\nSum of Odd Numbers from 1 to ", oddnum, " = ", Oddtotal)
}```
``````Enter the Number to find Odd Sum = 10
List of Odd Numbers from 1 to  10  are =
1       3       5       7       9
Sum of Odd Numbers from 1 to  10  =  25``````

## Golang Program to find Sum of Odd Numbers.

In this Golang program, we altered the for loop to start from 1 and increment by 2 to calculate the sum of odd numbers.

```package main

import "fmt"

func main() {

var oddnum, Oddtotal int

fmt.Print("Enter the Number to find Odd Sum = ")
fmt.Scanln(&oddnum)

Oddtotal = 0
fmt.Println("List of Odd Numbers from 1 to ", oddnum, " are = ")
for x := 1; x <= oddnum; x = x + 2 {
fmt.Print(x, "\t")
Oddtotal = Oddtotal + x
}
fmt.Println("\nSum of Odd Numbers from 1 to ", oddnum, " = ", Oddtotal)
}```
``````Enter the Number to find Odd Sum = 25
List of Odd Numbers from 1 to  25  are =
1       3       5       7       9       11      13      15      17      19      21  23       25
Sum of Odd Numbers from 1 to  25  =  169``````

This Go program calculates the sum of odd numbers from min to max. Here, we used an extra if statement to hold the user-entered value as odd by increment the even value (if any).

```package main

import "fmt"

func main() {

var Oddmin, Oddmax, Oddtotal int

fmt.Print("Enter the Minimum Odd Number = ")
fmt.Scanln(&Oddmin)
fmt.Print("Enter the Maximum Odd Number = ")
fmt.Scanln(&Oddmax)

if Oddmin%2 == 0 {
Oddmin++
}

Oddtotal = 0
fmt.Println("Odd Numbers from ", Oddmin, " to ", Oddmax, " = ")
for x := Oddmin; x <= Oddmax; x = x + 2 {
fmt.Print(x, "\t")
Oddtotal = Oddtotal + x
}
fmt.Println("\nSum of Odd Numbers from ", Oddmin, " to ", Oddmax, " = ", Oddtotal)
}```
``````Enter the Minimum Odd Number = 10
Enter the Maximum Odd Number = 50
Odd Numbers from  11  to  50  =
11      13      15      17      19      21      23      25      27      29      31  33       35      37      39      41      43      45      47      49
Sum of Odd Numbers from  11  to  50  =  600``````

It is identical to the first sum of odd Numbers example. However, it calculates the odd sum between the minimum and maximum limit.

```package main

import "fmt"

func main() {

var Oddmin, Oddmax, Oddtotal int

fmt.Print("Enter the Minimum Odd Number = ")
fmt.Scanln(&Oddmin)
fmt.Print("Enter the Maximum Odd Number = ")
fmt.Scanln(&Oddmax)

Oddtotal = 0
fmt.Println("Odd Numbers from ", Oddmin, " to ", Oddmax, " = ")
for x := Oddmin; x <= Oddmax; x++ {
if x%2 != 0 {
fmt.Print(x, "\t")
Oddtotal = Oddtotal + x
}
}
fmt.Println("\nSum of Odd Numbers from ", Oddmin, " to ", Oddmax, " = ", Oddtotal)
