c++ - Class array with multiple types? How to access one type in the array? -

here's small portion of code:

class student {     private:         string id, fname, lname, level;         double gpa; } 

so let's make array a[] of type student, there way access double 'gpa' of each array element? not sure how this. appreciated. need learn how google better because feel shouldn't hard still couldn't find looking for.

if have array

std::array<student, 10> students; 

you say

for (auto const& student : students) {     std::cout << student.gpa << " "; } 

you can arbitrary element well

students[i].gpa = 4.0; 

of course have make sure have public methods access these members if specified private

class student { public     student() = default;     student(double _gpa) : gpa(_gpa) {}      double get_gpa() const { return gpa; }     void set_gpa(double _gpa) { gpa = _gpa; }  private:     double gpa = 0.0; } 

then

students[i].set_gpa(4.0);
