How to insert the function on this program>
#include<iostream>
using namespace std;

struct Student_Record{
int id_num;
int assignment;
int quiz;
int test;
char grade;
};
void get_data(Student_Record &p);
int calc_mark(Student_Record p);
Student_Record read_data();
void print_all(const struct Student_Record p{});

int main()
{
Student_Record amir,naim, amirNaim[2];
int amirtotal_mark, naimtotal_mark;

get_data (amir);
amirtotal_mark=calc_mark(amir);
if (amirtotal_mark>=60)
amir.grade ='p';
else
amir.grade='F';

naim= read_data();
amirNaim[0]=amir;
amirNaim[1]=naim;

naimtotal_mark=calc_mark(amirNaim[1]);
if (naimtotal_mark>=60)
amirNaim[1].grade='P';
else
amirNaim[1].grade='F';

print_all(amirNaim);

system("pause");
return 0;
}

no people knowing this

What do you meant by "insert the function"?

[rezonk]

this question is complete the program.The program ask the user to enter mark for assignment,quiz and test for amir and naim,the calculates the total mark using simple formula (assignment+quiz+test)/3.Finally the program print report card for both students and the report display all content of the structure.You required to write definitions for the given 4 function performing task in the program.

So you want us to do your homework for you?

[rezonk]

want to ask how to solve this i try but nothing happen...

[rezonk]

want to ask who expert ....about this program

[Zhuge]

Start by considering what you need each method to do. The assignment has given you descriptions for each; how would you translate that into code?

[rezonk]

i not expert about c++ can you guide me...

[Zhuge]

Not if you don't even look like you've made an attempt.

i know

int calc_mark(Student_Record p);
{
int assignment;
int quiz;
int test;
amirtotal_mark=(assignment+quiz+test)/3;

return amirtotal_mark;
}

[rezonk]

void get_data(Student_Record &p);
{
int id_num;
int assignment;
int quiz;
int test;

cout<<"ID num: ";
cin>>id_num;
cout<<"Assingment: "
cin>>id_num
cout<<"Quiz: "
cin>>quiz;
cout<<"Test";
cin>>test;
}

[rezonk]

this what i done

void get_data(Student_Record &p);
{
int id_num,assignment,quiz,test;

cout<<"Put id num : ";
cin>>id_num;
cout<<"Assignment mark:";
cin>>assingment;
cout<<"Quiz mark: "
cin>>quiz;
cout<<"Test Mark: "
cin>>mark;
}
int calc_mark(Student_Record p)
{
int assignment,quiz,test;
amirtotal_mark=(assignment+quiz+test)/3
return amirtotal_mark;
}
Student_Record read_data()
{
cout<<id_num;
cout<<assignment;
cout<<quiz;
cout<<test;
}
void print_all(const struct Student_Record p{})
{
cout<<Student_Record.id_num;
cout<<Student_Record.assigment;
cout<<Student_Record.quiz;
cout<<Student_Record.test;
cout<<Student_Record.grade;
}

This not correct
