将结构向量推入结构中？

Question

i need to create a structure student that will nest another structure called course. and then fill the structure "course" with how many the student is enrolled in along with their id and name

I am not sure how can i pushback the structure "course" attributes into the structure student which already have the structure course as a vector in it

    #include <iostream>
    #include <string>
    #include<vector>
    using namespace std;

    struct course{

        int ID;
        string name;

    };
    struct student{
        int ID;
        string name;
        vector <course> ofcourses;


    };

    void studentDeclare(student &B1){

        int coursecount;
        cout <<" Student ID: " <<endl;
        cin>>B1.ID;
        cout <<" Student name: " <<endl;
        cin>>B1.name;
        cout <<" How many courses?: " <<endl;
        cin >> coursecount;

        int TempID;
        string TempName;
        for(int i = 0; i<coursecount;i++)
        {
            cout <<" Enter course ID: " <<endl;
            cin >> TempID;
            B1.ofcourses.ID.push_back[TempID];
            cout <<" Enter course name: " <<endl;
            string TempName;
            cin>>TempName;
            B1.ofcourses.name.push_back[TempName];
        }

    };

    int main()
{
    student boy;
    studentDeclare(boy);
    print(boy);

    system("pause");
}

Answer 1

B1.ofcourses.ID.push_back[TempID];
B1.ofcourses.name.push_back[TempName];

are not right.

B1.ofcourses is a std::vector<course> . It does not have a member named ID or name .

You need to construct a course object and push it to B1.ofourses .

for(int i = 0; i<coursecount;i++)
{
    course c;
    cout <<" Enter course ID: " <<endl;
    cin >> c.ID;
    cout <<" Enter course name: " <<endl;
    cin >> c.name;

    B1.ofcourses.push_back(c);
}
