C++ Solving problems

Hello, i'm a begginer in C++ and in programming, and i was thinking if anyone can help me solve some problems that my professor gave me.

The First Homework:

On the following program complete(Fullfill) the implementation everywhere where the sentence (be implemented) is : //Be implemented : ....

// Programi struct3

#include <iostream>

using namespace std;

struct person

{

char name[8],city[10];

int year;

int Nr_I_Exams;

int Grades[30];

int Grade_Average()

{

//Implement the method witch tells(sets) the average grade.

}

int Grade_Minimal()

{

//Implement the method witch tells(sets) the minimal grade.

}

int Grade_Max()

{

//Implement the method witch tells(sets) the maximal grade.

}

};

int main()

{

person student[4];

//Implement : For every student insert the following informations,where you – present iteratorin of rings…

cout << "\nInformations from Keyboard\n\n";

cout << "Name .....: ";

cin >> student[i].name;

cout << "City ...: ";

cin >> student[i].city;

cout << "Year.....: ";

cin >> student[i].year;

//Implement: Tell the grades number that is given
/ Implement: Put every grade on the structure list

// Implement: Enter the number of grades given

// Implement:Write the code where for student for example with number 1, 2 , 3 or 4, written Name, Surname,The number of grades given,minimal grade also average grade.

// Implement: Write the code where the notes are given for the student with highest average grade.
