Use of C program to subtraction of two numbers using recursion

In this tutorial, we will discuss the Use of C program to subtraction of two numbers using the recursion

In this topic, we are going to learn how to subtract two numbers (integer )using the recusive function in C language

already we are learned the same concept using the operator

if you want to remember click here, C program to subtract two numbers

program to subtraction of two numbers using recursion

The program allows to enter two integer numbers and then it calculates the subtraction of the given numbers using recursive function of C language

Program 1

#include <stdio.h>
#include <stdlib.h>
 int sub(int,int);//function prototype
int main()
{
    int num1,num2;//declare te variables
    printf("Enter two numbers: \n");
    scanf("%d%d",&num1,&num2);//read te value input from user
     printf("Subtraction of two numbers : %d",sub(num1,num2));//call the function
     getch();
    return 0;
}
int sub(int num1, int num2)//define the recursive function
{
    if(num2==0)
        return num1;
    else
        return sub((num1-1),(num2-1));

}

When the above code is executed, it produces the following result

Enter two numbers:
1200
500
Subtraction of two numbers : 700

Approach

Declare three int type variables num1,num2. num1,num2 are used to received input from the user
Receive input from the user for num1,num2 to perform subtraction
Define a recursive function to subtract two numbers
When the function is called, two numbers will be passed as argument subsequently the subtract of two numbers will be found
display the result on the screen
