Problem Description
The n schools participating in the sports meeting are numbered 1~n. The competition is divided into m men's events and w women's events, and the event numbers are 1~m and m+1~m+w respectively. Due to the large difference in the number of participants in each project, some projects only take the top five, and the scoring order is 7, 5, 3, 2, 1; some projects only take the top three, and the scoring order is 5, 3, 2. Write a statistical program to generate various transcripts and score reports.
basic requirements
Generate transcripts for each school, including the item number, ranking (score), name, and score of each achievement obtained by each school; generate a team total score report, including the school number, total score of the men's team, and total score of the women's team. and total team score.
Test Data
For n=4, m=3, w=2, the top five items with odd numbers are selected, and the top three items with even numbers are selected. Design a set of example data.
Implementation tips
It can be assumed that n<=20, m<=30, w<=20, and the name length does not exceed 20 characters. At the end of each event, enter its number and type (differentiate between the top five or the top three), and enter the athlete's name, school name (and results) in order of ranking.
Selected content
Allows users to specify other ranking methods for a certain project.
The sports meeting score statistics system menu is as follows:
Tips：
Enter nmw as the number of schools, the number of men's/women's events, then enter the name of each school, and then enter the event name, athlete name, school name and results in order.
Can support using file input instead of manual to facilitate testing
It can record the scores of all students in each school within a certain range. Although the student's score is 0, his scores can be recorded and output.
Target file name: sport.txt (It is recommended to read from the file first to prevent the program from crashing and re-entering the data)
Some personal thoughts:
Personally, I think this question is quite simple. I just thought about how to input the data for a long time. I originally wanted to classify and collect statistics by school, but there are many problems in operation and data storage, so I still ranked according to the requirements of the question. Sequential input, final data storage problem, and then traversal output.
The complete code is as follows:

#include <iomanip>
#include <conio.h>
#include <stdio.h>
#include <process.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
