C语言编程 有100个学生,试编程出按总分排名的名次表,打印出形式为:名次,学号,总分.

#include <iostream>
#include <algorithm>
#include <iomanip>

using namespace std;

const int Size = 100; // 学生人数

struct Student
{
int score;
int num;
inline friend bool operator < ( const Student &s1, const Student &s2 )
{
return s1.score > s2.score;
}
};

Student Stu[ Size ];

void init( )
{
int i;
for ( i = 0; i < Size; i++ )
{
cout << "请输入第" << i + 1 << "个学生的学号和成绩：";
cin >> Stu[ i ].num >> Stu[ i ].score;
}
}

void print( )
{
int i;
cout << setw( 6 ) << "名次" << setw( 6 ) << "学号" << setw( 6 ) << "总分" << endl;
for ( i = 0; i < Size; i++ )
cout << setw( 6 ) << i + 1
<< setw( 6 ) << Stu[ i ].num
