Thread: How to write a program for...

How to write a program for printing all odd numbers between 1 and 100 using while loop?

I know the logic but I am not able to put it into the while loop and get an output.

Please help. Thanks in advance.

Yup I can print all integers between 1 and 100. here is the program for that.

Code:

void main()
{
     
     int n=1; 
          
     while (n<=100)
           {
           
           printf ("%d\t",n);
           n++; 
                   
           }
           
     
     getch();
}

But now how do i print only odd nos now

if i use n=n+2 i am getting an output.

but isn't there any way to use the n%2 logic within this while loop.

Yes it is, but skipping the numbers in this case is faster...
If you insist on using n%2, you can use the loop that prints the first 100 integers and just before calling printf() check if n is odd like this...

Code:

// Only prints n it's odd (if n modulo 2 is not zero)
if (n%2) printf ("%d\t", n);
