Enhance features

[miniedattu]

Hi Team/@Mrinank-Bhowmick ,

"I'm always frustrated when a program stops working without the user's permission. It is happening with this program."
"I can see repeated lines in the program. "
"I am getting some error messages when I give some input values."

Describe the solution you'd like
I would like to solve the issues, make a smart coding in the healthmanagement program.

Describe alternatives you've considered
Also I would like to add a personal information file for each individual.

Can you please assign this to me ? I will assure you that I will meet the community guidelines for contributor's.

Thank you for the consideration.
