Print total odd numbers from 1 to n

C Program

1. For Loop

#include <stdio.h>
#include <stdlib.h>
int main()
{
   int n,i;
   printf("Enter any number:");
   scanf("%d",&n);
   printf("Total odd number from 1 to %d is:\n",n);
   for(i=1;i <=n;i++)
   {
       if(i%2!=0)
        printf("%d ",i);
   }
}

2. While Loop

#include <stdio.h>
#include <stdlib.h>

int main()
{
   int n,i;
   printf("Enter any number:");
   scanf("%d",&n);
   printf("Total odd number from 1 to %d is:\n",n);
   i=1;
  while(i <=n)
  {
      if(i%2!=0)
         printf("%d ",i);
      i++;
  }
}

3. Do While Loop

#include <stdio.h>
#include <stdlib.h>

int main()
{
   int n,i;
   printf("Enter any number:");
   scanf("%d",&n);
   printf("Total odd number from 1 to %d is:\n",n);
   i=1;
  do
  {
       if(i%2!=0)
         printf("%d ",i);
      i++;
  }while(i<=n);
}
