Program to print N natural number

Input - Output

Input
Enter range to print natural number: 9

Output
First 9 natural number are:1 2 3 4 5 6 7 8 9

Algorithm

Step 1: START

Step 2: Enter range to print natural number

Step 3: Apply Condition: for(i=1;i<=num;i++)

        print i;

Step 4: END

CODE


/* Print N natural number */

#include<stdio.h>
int main()
{
      int num;
      printf(" Enter a number : ");
      scanf("%d",&num);
      printf(" First %d natural numbers are : ",num);
      for(int i=1;i<=num;i++)
      printf(" %d",i);
    return 0;
}


/* Print N natural number */

#include<iostream>
using namespace std;
int main()
{
      int num;
      cout<<" Enter a number : ";
      cin>>num;
      cout<<" First "<<num<<" natural numbers are : ";

      cout<<i<<" ";
    return 0;
}

OutPut

Enter range to print natural number: 9

First 9 natural number are:1 2 3 4 5 6 7 8 9
