Write the definition of the constructor in Line 7 so that the instance variables are initialized according to the parameters. Instance variables quantitiesInStock, price.and discount must be nonnegative.

Explanation / Answer

a)
i)Line 4//default constructor will be executed
ii)Line 7//that was the only constructor which has 6 parameters
iii)Line 6// this was the only constructor that has match
iv)Line 5
b)
ProductType::ProductType()
{
productname="";
id="";
manufacturer="";
quantitiesInStock=0;
price=0.0;
discount=0.0;
}
c)
ProductType::ProductType(int i,double d,double e)
{
productname="";
id="";
manufacturer="";
if(i<0)
quantitiesInStock=0;
else
quantitiesInStock=i;
if(d<0)
price=0.0;
else
price = d;
if(e<0)
discount=0.0;
else
discount=e;
}
d)
ProductType::ProductType(string s,int i,double d,double e)
{
productname="";
id=s;
manufacturer="";
if(i<0)
quantitiesInStock=0;
else
quantitiesInStock=i;
if(d<0)
price=0.0;
else
price = d;
if(e<0)
discount=0.0;
else
discount=e;
}
e)
ProductType::ProductType(string s1,string s2,string s3,int i,double d,double e)
{
productname=s11;
id=s2;
manufacturer=s3;
if(i<0)
quantitiesInStock=0;
else
quantitiesInStock=i;
if(d<0)
price=0.0;
else
price = d;
if(e<0)
discount=0.0;
else
discount=e;
}
