Scope problems

[CoopDH]

Im having a problem with scope errors. Im trying to use a function from my class and even with including the class file it isnt working.
proj1.cc

#include "food.h"
#include <iostream>
#include <iomanip>
#include <string>

int main () {
do{
    menu();
    cout << "Enter a number between 0 and 8";
    cin >>  loop;
    
        switch (loop){
        case 1:
            print (lunch);
            cout << endl << endl;
            break;
   ..........
    return 0;
    }

food.h

using namespace std;
#ifndef _FOOD_H_
#define _FOOD_H_
#include <string>
#include <iostream>
class food
{
    public:
       void print(const food& a);
        food choose (food& f1, food& f2, food& f3, food& f4, food& f5, food& f6);
    private:
	    string name;
	    double protein;
	    double fiber;
	    double fat;
	    double calories;
}
#endif // _FOOD_H_ 

food.cc

#include "food.h"
#include <string>
#include <iostream>

 // *******************************************************************************
 print (food& a){
    cout<< a.name << endl;
	cout << "protein: " << a.protein << endl;
	cout << "fiber:" << a.fiber << endl;
	cout << "fat:" << a.fat << endl;
	cout << "calories:" << a.calories << endl;
	}
// *******************************************************************************
 choose (food& f1, food& f2, food& f3, food& f4, food& f5, food& f6){
 int temp;
 cout << "choose a food" << endl << endl << "1";
 print (f1);
 cout << endl << endl << "2";
 print (f2);
 cout << endl << endl << "3";
 print (f3);
 cout << endl << endl << "4";
 print (f4);
 cout << endl << endl << "5";
 print (f5);
 cout << endl << endl << "6";
 print (f6);
 cout << endl << endl;
 cin >> "enter a number from 1-6" >> temp;
 switch (temp){
        case 1:
            return f1;
        case 2:
            return f2;
        case 3:
            return f3;
        case 4:
            return f4;
        case 5:
            return f5;
        case 6:
            return f6;
     }
  }

the errors specifically i am getting is
error: ‘print’ was not declared in this scope
error: ‘choose’ was not declared in this scope

It looks like you want to include food.cc not food.h in your main file...

//proj1.cc (1)
#include "food.cc" //food.h is included in food.cc already, so you don't need both here  

FYI: classes end with a ;

//food.h (17)
}; // <- need the ; here 
#endif // _FOOD_H_

No, that isn't necessary and in fact it's generally not a good thing to do...

First, you do need a ; at the end of your class as stated above.
Second, your functions are missing their scope operators...
e.g.:
food::print(food& a)
Third, your functions seem like they are supposed to be global functions, not members anyway.

Thanks guys,
After getting this bug solved now im getting another one in multiple areas.
error: expected initializer before ‘operator’
