Answer:
18
Explanation:
lets go step by step.
the function called tryIt has a value, a variable named "a". this "a" variable will be whatever the user enters when the program says, Enter a number.
ok so if we enter "a" as 2, and b in the function will always be 7, and 2 + 7 equals 9,
and the ans variable (short for answer) will take the result of the function (9) and multiply it by 2,
then the answer is 18
Yes wizard function allows you to modify records
Answer:
#include <iostream>
using namespace std;
class ProblemSolution {
private:
int num1, num2;
public:
ProblemSolution(int n1, int n2) {
num1 = n1;
num2 = n2;
}
int calculateSum() {
int sum = 0;
sum = num1 + num2;
return sum;
}
void printSum() {
// calculateSum will return sum value that will be printed here
cout <<"Sum = "<< calculateSum();
}
~ProblemSolution() {
cout << "\nDestructor is called " << endl;
};
};
int main() {
int a, b;
cout << "Enter a: ";
cin >> a;
cout << "Enter b: ";
cin >> b;
// Initiallizing object pointer of type ProblemSolution
ProblemSolution *objPtr = new ProblemSolution(a,b);
// printing Sum
objPtr->printSum();
// delete objPtr to relaease heap memory :important
delete objPtr;
return 0;
}
Explanation:
we will initialize a pointer "objPtr" and initallize the constructor by passing 2 values a and b followed by the keyword "new". the keyword "new" allocates memory in the heap. we can access class member functions using arrow "->". it is important to delete objPtr at the end of the program so that the heap memory can be freed to avoid memory leakage problems.
Terence is involved in the <u>design phase</u> of software development life cycle (SDLC).
<h3>What is SDLC?</h3>
SDLC is an acronym for software development life cycle and it can be defined as a strategic process (methodology) that defines the key steps, phases, and stages for the development and implementation of high quality software applications.
<h3>The phases of SDLC</h3>
Generally, there are six (6) main phases involved in the development of a software application and these include;
In this scenario, Terence is creating software requirements specification (SRS) documents and as such is involved in the design phase of software development life cycle (SDLC).

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.
