Thanks
you need a constructor without parameter:
1
2

|
Food()
{
water=0;
chicken=0;
}
|
or default parameter:
1
2
3
4
5
|
Food(int w = 0,int c = 0)
{
water=w;
chicken=c;
}

YOU ARE FUCKING PERFECT.THAAAAAAAAAAAANKS.
That was fantastic explanation.
But can exaplain me why i need put as first value the zero?
It was an example. You can use whatever value you prefer.

Food operator+(const Food &c1, const Food &c2)
{
return Food(
c1.water+c2.water,
c1.chicken+c2.chicken,
);
}
int main(){
Food ce1(6,3),ce2(8,4);
Food cCentsSum = ce1 + ce2;
cCentsSum.GetCents();
return 0;
}

You were trying to construct a Food object without providing its values.
That's like going to the electronic store and ask for an integrated circuit.
