Find the sum of odd numbers using recursion

Problem statement:- Program to find the sum of odd numbers using recursion.

Data requirement:-

   Input Data:- num2

  Output Data:-
SumOdd(num1,num2)

Program in C

Here is the source code of the C Program to find the sum of odd numbers using recursion.

Code:

#include<stdio.h>
int SumOdd(int num1, int num2)
{
   if(num1>num2)
    return 0;
return num1+SumOdd(num1+2,num2);
}
int main()
{
    int num1=1,num2;
    printf("Enter your Limit:");
    scanf("%d",&num2);
    printf("Sum of all odd numbers in the given range is: %d",SumOdd(num1,num2));
}

Input/Output:
Enter your Limit:12
Sum of all odd numbers in the given range is: 36

Program in C++

Here is the source code of the C++ Program to find the sum of odd numbers using recursion.

Code:

#include<iostream>
using namespace std;
int SumOdd(int num1, int num2)
{
   if(num1>num2)
    return 0;
return num1+SumOdd(num1+2,num2);
}
int main()
{
    int num1=1,num2;
    cout<<"Enter your Limit:";
    cin>>num2;
    cout<<"Sum of all odd numbers in the given range is:"<<SumOdd(num1,num2);
}

Input/Output:
Enter your Limit:5
Sum of all odd numbers in the given range is:9

Program in Java

Here is the source code of the Java Program to find the sum of odd numbers using recursion.

Code:

import java.util.Scanner;
public class FindSumOfOddNumber {
static int SumOdd(int num1, int num2)
{
   if(num1>num2)
    return 0;
return num1+SumOdd(num1+2,num2);
}
public static void main(String[] args) {
           Scanner cs=new Scanner(System.in);
    int num1=1,num2;
    System.out.print("Enter your Limit:");
    num2=cs.nextInt();
System.out.print("Sum of all odd numbers in the given range is:"+SumOdd(num1,num2));
        cs.close();
}
}

Input/Output:
Enter your Limit:25
Sum of all odd numbers in the given range is:169

Program in Python

Here is the source code of the Python program to find the sum of odd numbers using recursion.

Code:

def SumOdd(num1,num2):
    if num1>num2:
        return 0

    return num1+SumOdd(num1+2,num2)
num1=1
print("Enter your Limit:")
num2=int(input())
print("Sum of all odd numbers in the given range is:",SumOdd(num1,num2))

Input/Output:
