实验5(1) 参考答案

char * GetName( ) { return name; } int GetScore( ) { return score; } Date GetDate( ) { return birthday; } private: char name[20]; int score; Date birthday; };

int CompareDate( Date d1, Date d2 ); void SortByName( Student *, int num ); void SortByScore( Student *, int num ); void SortByBirthday( Student *, int num ); void PrintStudent( Student *, int num );

int main( ) {

Student st[5] = {Student(1990,2,5,99,\

Student(1989,12,25,62,\ Student(1990,3,14,88,\Student(1989,10,15,74,\Student(1990,5,22,92,\

PrintStudent( st,5); cout<

int CompareDate( Date d1, Date d2 ) { //int t;

if (d1.GetYear()

else if(d1.GetYear()==d2.GetYear()) if(d1.GetMonth()

void SortByName( Student *st, int num ) { Student t; int k; for(int i=0;ist[j].GetName()) if(strcmp(st[k].GetName(),st[j].GetName() )>0) k=j; t=st[k]; st[k]=st[i]; st[i]=t; } }

void SortByScore( Student *st, int num ) { Student t; int k; for(int i=0;i

st[i]=t; } }

void SortByBirthday( Student *st, int num ) { Student t; int k; for(int i=0;i

void PrintStudent( Student *st, int num ) { for (int i=0;i

运行结果为： Jack 99 1990-2-5 Mike 62 1989-12-25 Tom 88 1990-3-14 Kate 74 1989-10-15 Rowen 92 1990-5-22

三、实验指导

题目1指导：

① 程序的主要代码如下，在横线上补充相应的语句。

#include using namespace std; class Member1 { public: };

class Member2 { public:

Member2( （1） ): （2） { }

~Member2( ) { }

void show( ) { }

cout << \cout << \y = c;

cout << \Member1(int a) { }

~Member1( ) { }

void show( ) { } int x;

cout << \cout << \x = a;

cout << \
