n的值>=2时为什么输出的值有空格等错误，求解。#include<iostream>#include<string>using namespace std;class Student{public: string id; string name; float score[3]; float sum_m;};Student* fun(float p[],int n,Student *student){ float temp; Student demp; for(int i=0;i<n;i++) for (int j = 0;j < i - j;j++) { if (p[j] < p[j + 1]) { temp = p[j+1]; p[j+1] = p[j ]; p[j] = temp; demp = student[j+1]; student[j + 1] = student[i]; student[j] = demp; } } for (int i=0;i < n;i++, student++) { cout << student->id << " "<< student->name << " " << student->sum_m <<" "<< endl; } return student;}int main(){ int n; cin >> n; Student *student =new Student[n]; float* p = new float[n]; for (int i = 0;i < n;i++) { student->sum_m = 0; cin >> student->id; cin >> student->name; for (int j = 0;j < 3;j++) { cin >> student->score[j]; student->sum_m += student->score[j]; cout << " "; } p[i] = student->sum_m; } fun(p, n, student); return 0;}
