Make a Class Cricket_Team with following attributes:
– Team Name
– Player Name
– Batting Average
Read the details various players from different team in random.
Now print the team wise list of players in the sorted order of their batting averages.

Use functions:
– To read the player detail
– To arrange the players team wise
– To sort the batting average
– To Print the details

Q7. Program Matrix manipulation (menu based):

Make a structure Student with following fields:
– Name
– Roll No.
– Result (Structure)
– – Total Marks Obtained
– – Max_Marks
– – Percentage

Read the list of students (At least 3) in a class.
Now compare the results of all the students and Rank top 3 students in the whole class.
