Write code to allow the user to enter a positive integer. Compute and display the sum of the odd integers from $1$ to the entered integer, including the entered integer if it is odd.

For example, if the user enters $11,$ then $1+3+5+7+9+11$ is computed.

If the user enters $12,$ then $1+3+5+7+9+11$ is computed.

For example:

Input Result

$11$

Enter an integer: $11$

Sum of the odds is $36$

$12$

Enter an integer: $12$

Sum of the odds is $36$
