Kategori : descending function order recursive
Write a program in which a function takes input from user and print numbers in descending order using recursion. Make proper prototype with one integer as argument and return an integer.
hint: int decrement(int);
Program Logic Explanation
C++ Source Code
Example input output
It is recommended to change the code, dry run on a paper and examine the output.

hint: int decrement(int);
Program Logic Explanation
- In this program we have a function having an if-else statement
- If and else both have return on the basis of certain conditions.
- If condition has the base case which means that program output will not return result
until the base case is true - As we know function returns from where it has called so if user enters 5 then function will be
called 5 times one from the outside and 4 times form else statement when base case becomes
true it returns in else to 4 times and finally 5th time to main body
C++ Source Code
#include<iostream>
using namespace std;
int decrement(int);
int main()
{
int number;
cout<<"Enter number to get decrement using recursion";
cin>>number;
cout<<decrement(number);
cout<<" "<<endl;
return 0;
}
int decrement(int num)
{
if(num==1)
{
return 1;
}
else
{
cout<<num<<" ";
return decrement(num-1);
}
}
