What is Selection Structure? How It will be use in CPP?

 Practice # 9.1

Here we discuss about selection structure where in use if else-if  else ladder. And we make a small program of a theme park entry system to use the if else-if else ladder in selection structure. I have given the output image below. Probably it will be cool for you. I have also given the full program source code down there. You can check the previous practices, if you will don't understand anything on this blog for getting knowledge. And also you can contact me any further knowledge.

#include<iomanip>
