Answer:
Check the explanation
Explanation:
bool oneSale(string item){
for(int i=0;i<capacity;i++){ // iterate till the capcity of array
if(item==grocerryList[i].name()){ // if name matches
if(grocerryList[i].getStock()>0){ // and stock is greater than 0
grocerryList[i].setStock(grocerryList[i].getStock()-1); // subtract 1 from the stock
// or alternate is grocerryList[i].stock= grocerryList[i].stock-1;
return true; // return true
}
}
else if(item==grocerryList[i].name()){ // if name matches
if(grocerryList.getStock()==0){ // but stock is empty
return false; // return falsse
}
}
else{ // means item is not available so there is no need to check stock
return false; // return false
}
}
}
computers got smaller because one of its main components the valve – was replaced by the much smaller transistor.
Passing by reference is used if a parameter's data flow is two-way, into and out of the function.
C. two-way, into and out of the function.
<u>Explanation:</u>
If a function in programming language passing the parameter by reference means it only sending the address of parameter to a function. If any value is changed on reference parameter it will changed original value.
If parameter passed by value means it is one way, where value been send to the function.
Whereas by reference means it two-way, in and out of the function. Mostly it called as pointer.
It is available in c , c++, where declare of variable “*” or “&” address off.

Answer:
This will result in a compilation error.
Here's the inheritance hierarchy:
Meg -> Lois -> Brian -> Stewie
Now Meg has 2 public Fxns, a() and toString().
Lois inherits from Meg and all its public functions as well but, overrides the a() fxn of its super class.
So finally Lois has fxns a(), b() and toString().
Brian extends Lois and inherits all the above listed fxns of Lois, but overrides the b() and toString() fxns.
Stewie extends Brian and inherits all the fxns of Brian, but overrides the a() and toString() fxns.
In the Main driver fxn, we call a() and b() methods of all these classes but, the base class Meg has no b() and it is not extending any class so its not available in its scope.
This results in a compilation error.
