C Program to Print Natural Numbers From N to 1 in Reverse Order

C program to print all natural numbers from n to 1; Through this tutorial, we will learn how to c program to print all natural numbers from n (10, 100, 500, 1000, etc) to 1 using for loop, while loop and recursion function.

Programs to Print Natural Numbers from N to 1 in C

• C Program to Print Natural Numbers From N to 1 in Reverse Order using While Loop
• C Program to Print Natural Numbers From N to 1 in Reverse Order using For Loop
• C Program to Print Natural Numbers From N to 1 in Reverse Order using Recursion

C Program to Print Natural Numbers From N to 1 in Reverse Order using While Loop

/* C Program to Print Natural Numbers in reverse using While Loop */

#include<stdio.h>

int main()
{
  	int Number, i;

    printf("\n Please Enter any Integer Value  : ");
  	scanf("%d", &Number);

  	i = Number;
  	printf("\n List of Natural Numbers from %d to 1 are \n", Number);

	while(i >= 1)
  	{
    	printf(" %d \t", i);
    	i--;
  	}

  	return 0;
}

The output of the above c program; as follows:

Please Enter any Integer Value  : 10
List of Natural Numbers from 10 to 1 are
 10 	 9 	 8 	 7 	 6 	 5 	 4 	 3 	 2 	 1 	

C Program to Print Natural Numbers From N to 1 in Reverse Order using For Loop

/* C Program to Print Natural Numbers from 1 to N using For Loop */

#include<stdio.h>

int main()
{
  	int Number, i;

  	printf("\n Please Enter any Integer Value  : ");
  	scanf("%d", &Number);

  	printf("\n List of Natural Numbers from %d to 1 are \n", Number);
	for(i=Number; i>=1; i--)
  	{
    	printf(" %d \t", i);
  	}

  	return 0;
}

The output of the above c program; as follows:

Please Enter any Integer Value  : 10
List of Natural Numbers from 10 to 1 are
 10 	 9 	 8 	 7 	 6 	 5 	 4 	 3 	 2 	 1 	

C Program to Print Natural Numbers From N to 1 in Reverse Order using Recursion

#include<stdio.h>

void display(int);

int main()
{
    int limit;

    printf("Please Enter any Integer Value  : ");
    scanf("%d", &limit);

    printf("\nNatural Numbers from 1 To %d are:", limit);
    display(limit);

    return 0;
}

void display(int num)
{
    if(num <= 0)
        return;
    else
      printf(" %d ", num);
      display(num-1);


}  

The output of the above c program; as follows:

Please Enter any Integer Value  : 10
Natural Numbers from 1 To 10 are: 10  9  8  7  6  5  4  3  2  1
