C++ program

Hello, I would be very grateful if you help me complete this program. The task is as follows:
Sports Federation of the office with information about the teams: team number. The name, played games, to win the match number, lose the match number, position.
Create a menu that lets you choose the action:
• displaying data on a computer screen
• Data Entry
• Data correction
• Data emissions
• List of sorting
• Search by location and occupied the team no.
• Program completion
Find loses a percentage of the number of matches played. Print a list sorted by the number of matches played.

I'm sorry, but English is little understood, so for any errors.
Here is my program code.

I want to see these two paragraphs code:
• List of sorting
• Search by location, and the team occupied No.
