C/C++：vector中存放结构体类型变量
1、设结构体类型变量为：
typedef struct student
{
char school_name[100];
char gender;
int age;
bool is_absent;
} StudentInfo;
2、vector存放结构体类型变量的副本：
#include <iostream>
#include <string>
#include <vector>
//struct
typedef struct student
{
char school_name[100];
char gender;//xing bie
int age;
bool is_absent;
} StudentInfo;
typedef std::vector<StudentInfo> StudentInfoVec;//sheng ming
void print(StudentInfoVec *stduentinfovec)
{
for (int j=0;j<(*stduentinfovec).size();j++)//bian li vector
{
std::cout<<(*stduentinfovec)[j].school_name<<"\t"
<<(*stduentinfovec)[j].gender<<"\t"
<<(*stduentinfovec)[j].age<<"\t"
<<(*stduentinfovec)[j].is_absent<<"\t"
<<std::endl;
}
}
int main()
{
StudentInfo micheal={"Micheal",'m',18,false};
StudentInfo cherry={"Cherry",'f',16,true};
StudentInfoVec studentinfovec;//dui xiang
studentinfovec.push_back(micheal);
studentinfovec.push_back(cherry);
print(&studentinfovec);
system("pause");
return 0;
}
3、vector存放指向结构体类型变量的指针：
#include <iostream>
#include <string>
#include <vector>
//struct
typedef struct student
{
char* school_name;
char gender;
int age;
bool is_absent;
} StudentInfo;
typedef std::vector<StudentInfo*> StudentInfoPtrVec;
void print(StudentInfoPtrVec*stduentinfoptrvec)
{
for (int j=0;j<(*stduentinfoptrvec).size();j++)
{
std::cout<<(*stduentinfoptrvec)[j]->school_name<<"\t"
<<(*stduentinfoptrvec)[j]->gender<<"\t"
<<(*stduentinfoptrvec)[j]->age<<"\t"
<<(*stduentinfoptrvec)[j]->is_absent<<"\t"
<<std::endl;
}
}
int main()
{
StudentInfoPtrVec studentinfoptrvec; //dui xiang
char* p_char_1=NULL;
p_char_1=new char[100];
strcpy(p_char_1,"Micheal");
StudentInfo* p_student_1=new StudentInfo;
p_student_1->school_name=p_char_1;
p_student_1->gender='m';
p_student_1->age=18;
p_student_1->is_absent=false;
studentinfoptrvec.push_back(p_student_1);
char* p_char_2=NULL;
p_char_2=new char[100];
strcpy(p_char_2,"Cherry");
StudentInfo* p_student_2=new StudentInfo;
p_student_2->school_name=p_char_2;
p_student_2->gender='f';
p_student_2->age=16;
p_student_2->is_absent=false;
studentinfoptrvec.push_back(p_student_2);
print(&studentinfoptrvec);
delete p_char_1;
delete p_student_1;
delete p_char_2;
delete p_student_2;
system("pause");
return 0;
}
