Problem statement:- Program to Find subtraction of two numbers using recursion.

Data requirement:-

   Input Data:- num1, num2

  Output Data:-Subtraction(num1,num2)

Program in C

Here is the source code of the C Program to Find subtraction of two numbers using recursion.

Code:

#include<stdio.h>
int Subtraction(int num1, int num2)
{
   if(num2==0)
    return num1;
   return Subtraction(num1-1, num2-1);
}
int main()
{
    int num1, num2;
    printf("Enter the two Number:");
    scanf("%d%d",&num1,&num2);
    printf("Subtraction of Two Number Using Recursion is:%d",Subtraction(num1,num2));
}

Input/Output:
Enter the two Number:50
10
Subtraction of Two Number Using Recursion is:40

Program in C++

Here is the source code of the C++ Program to Find subtraction of two numbers using recursion.

Code:

#include<iostream>
using namespace std;
int Subtraction(int num1, int num2)
{
   if(num2==0)
    return num1;
   return Subtraction(num1-1, num2-1);
}
int main()
{
    int num1, num2;
    cout<<"Enter the two Number:";
    cin>>num1>>num2;
   cout<<"Subtraction of Two Number Using Recursion is:"<<Subtraction(num1,num2);
}

Input/Output:
Enter the two Number:100
300
Subtraction of Two Number Using Recursion is:-200

Program in Java

Here is the source code of the Java Program to Find subtraction of two numbers using recursion.

Code:

import java.util.Scanner;
public class SubtractionOfTwoNumberUsingRecursion {
static int Subtraction(int num1, int num2)
{
   if(num2==0)
    return num1;
   return Subtraction(num1-1, num2-1);
}
public static void main(String[] args) {
Scanner cs=new Scanner(System.in);
int num1, num2;
    System.out.print("Enter the two Number:");
    num1=cs.nextInt();
    num2=cs.nextInt();
System.out.print("Subtraction of Two Number Using Recursion is: "+Subtraction(num1,num2));
        cs.close();
}
}

Input/Output:
Enter the two Number:41
32
Subtraction of Two Number Using Recursion is: 9

Program in Python
